<p>4.提交cocoa pods (这个有点耐心, 需要会时间)</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">pod trunk push EMTest.podspec</div></pre></td></tr></table></figure>

<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">pod search EMTest</div></pre></td></tr></table></figure>
<p>6.如果搜索不出来 更新下cocoapods</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">pod setup</div></pre></td></tr></table></figure>
<p>7.如果还是没有，一直显示</p>
<blockquote>
<p>[!] Unable to find a pod with name, author, summary, or description matching <code>EMTest</code></p>
</blockquote>
<p>执行</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">rm ~/Library/Caches/CocoaPods/search_index.json</div></pre></td></tr></table></figure>

<p>2.创建仓库<br><img src="/img/2018:02:08_145301.jpg" alt="outputScreen"></p>
<h2 id="二-制作SSH-KEY"><a href="#二-制作SSH-KEY" class="headerlink" title="二.制作SSH-KEY"></a>二.制作SSH-KEY</h2><p>1.生成SSH-Key<br>打开终端查看是否已经存在SSH密钥：<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">cd ~/.ssh</div></pre></td></tr></table></figure></p>
<p>如果没有密钥则不会有此文件夹，有则备份删除, 也可以直接删除；</p>
<p>2.生成新的秘钥, 命令如下</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">ssh-keygen -t rsa -C "1441699953@qq.com"</div></pre></td></tr></table></figure>
<p>你需要把邮件地址换成你自己的邮件地址，然后一路回车，使用默认值即可，因为这个Key仅仅用于简单的服务，所以也无需设置密码。</p>
<p>3.自定义生成key的名字(直接回车)<br><img src="/img/2018:02:08_134804.jpg" alt="outputScreen"></p>
<p>4.设置密码(直接回车)<br><img src="/img/2018:02:08_135005.jpg" alt="outputScreen"></p>
<p>5.成功生成SSH-Key<br><img src="/img/2018:02:08_135106.jpg" alt="outputScreen"></p>
<p>6.在~/.ssh/目录下会生成id_rsa和id_rsa.pub私钥和公钥。我们将id_rsa_emeet.pub中的内容粘帖到服务器的SSH-key的配置中。<br>可以用查看命令</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">cat id_rsa.pub</div></pre></td></tr></table></figure>

<content type="html"><![CDATA[<h2 id="工程创建"><a href="#工程创建" class="headerlink" title="工程创建"></a>工程创建</h2><p>1.打开Xcode -> Create a new Xcode project,然后选择如图的Cocoa Touch Framework, 选择语言、填好包名，组织名<br><img src="/img/2018:01:19_164701.jpg" alt="outputScreen"></p>
<p>2.工程的Targets下的配置General -> Deployment Info下的Deplayment Target 设置使用的最低版本，我们就设置成9.0便于说明</p>
<p>3.工程的Targets下的配置Build Settings -> Linking下的Mach-O type 设置为Static Library<br><img src="/img/2018:01:20_101602.png" alt="outputScreen"></p>
<h2 id="代码示例"><a href="#代码示例" class="headerlink" title="代码示例"></a>代码示例</h2><p>1.新建三个类test1、test2、test3<br>代码基本如下：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">@interface Test1 : NSObject</div><div class="line"></div><div class="line">- (void)print;</div><div class="line"></div><div class="line">@end</div></pre></td></tr></table></figure>
<p>test2、test3同理</p>
<p>2.然后设置test1.h和test1.m完全对外公开、Test2.h公开，test2.m隐蔽、test3.h和test3.m不对外公开</p>
<p>3.工程的Targets下的配置Build Phases -> Headers下的文件根据上面所示，如下设置，<br>注意：新建一个类的时候，默认Project会默认对应该类的头文件，如果需要完全公开，.m也要对外的话，点击下面的“+”,添加.m，然后将其拖到Public之中,要对外的都放入Public，不对外的放入Project；<br><img src="/img/2018:01:20_153303.png" alt="outputScreen"></p>
<h2 id="生成真机和模拟器合并framework"><a href="#生成真机和模拟器合并framework" class="headerlink" title="生成真机和模拟器合并framework"></a>生成真机和模拟器合并framework</h2><p>问题：framework如果选择真机运行Products会生成真机framework，只能在真机运行，不能再模拟器运行，同理如果选择模拟器运行Products会生成模拟器framework，只能在模拟器运行，不能在真机运行；</p>
<p>为了解决以上问题，我们可以通过脚本生成生成真机和模拟器合并framework</p>
<p>1.Xcode -> File -> Target -> Cross-platform 下面的 other 点击 Aggregate 然后输入了脚本名EMAggregate<br><img src="/img/2018:01:20_154804.png" alt="outputScreen"></p>
<p>2.工程的Targets下EMAggregate 的 Build Phases 点击左上角“+”，选择New Run Script Phase;<br><img src="/img/2018:01:20_155205.png" alt="outputScreen"></p>
<p>3.添加如下代码：</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div><div class="line">11</div><div class="line">12</div><div class="line">13</div><div class="line">14</div><div class="line">15</div><div class="line">16</div><div class="line">17</div><div class="line">18</div><div class="line">19</div><div class="line">20</div><div class="line">21</div><div class="line">22</div><div class="line">23</div><div class="line">24</div><div class="line">25</div><div class="line">26</div><div class="line">27</div><div class="line">28</div><div class="line">29</div><div class="line">30</div><div class="line">31</div><div class="line">32</div><div class="line">33</div><div class="line">34</div><div class="line">35</div><div class="line">36</div><div class="line">37</div><div class="line">38</div><div class="line">39</div><div class="line">40</div><div class="line">41</div><div class="line">42</div><div class="line">43</div><div class="line">44</div><div class="line">45</div><div class="line">46</div><div class="line">47</div><div class="line">48</div><div class="line">49</div><div class="line">50</div><div class="line">51</div></pre></td><td class="code"><pre><div class="line"># Sets the target folders and the final framework product.</div><div class="line"></div><div class="line"># 如果工程名称和Framework的Target名称不一样的话，要自定义FMKNAME</div><div class="line"></div><div class="line"># 例如: FMK_NAME = "MyFramework"</div><div class="line"></div><div class="line">FMK_NAME=${PROJECT_NAME}</div><div class="line"></div><div class="line"># Install dir will be the final output to the framework.</div><div class="line"></div><div class="line"># The following line create it in the root folder of the current project.</div><div class="line"></div><div class="line">INSTALL_DIR=${SRCROOT}/Products/${FMK_NAME}.framework</div><div class="line"></div><div class="line"># Working dir will be deleted after the framework creation.</div><div class="line"></div><div class="line">WRK_DIR=build</div><div class="line"></div><div class="line">DEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.framework</div><div class="line"></div><div class="line">SIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework</div><div class="line"></div><div class="line"># -configuration ${CONFIGURATION}</div><div class="line"></div><div class="line"># Clean and Building both architectures.</div><div class="line"></div><div class="line">xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos clean build</div><div class="line"></div><div class="line">xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator clean build</div><div class="line"></div><div class="line"># Cleaning the oldest.</div><div class="line"></div><div class="line">if [ -d "${INSTALL_DIR}" ]</div><div class="line"></div><div class="line">then</div><div class="line"></div><div class="line">rm -rf "${INSTALL_DIR}"</div><div class="line"></div><div class="line">fi</div><div class="line"></div><div class="line">mkdir -p "${INSTALL_DIR}"</div><div class="line"></div><div class="line">cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/"</div><div class="line"></div><div class="line"># Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product.</div><div class="line"></div><div class="line">lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}"</div><div class="line"></div><div class="line">rm -r "${WRK_DIR}"</div><div class="line"></div><div class="line">open "${INSTALL_DIR}"</div></pre></td></tr></table></figure>

<content type="html"><![CDATA[<h2 id="问题"><a href="#问题" class="headerlink" title="问题"></a>问题</h2><p>最近在工程使用到了第三方提供的SDK，有的第三方提供的是framework的是动态库，只提供真机和模拟器，如果的想同时支持真机和模拟，一想到就是合并，输出一个通用framework</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">lipo -create 【模拟器打包path】 【真机打包path】 -output 【导出兼容版本path】</div></pre></td></tr></table></figure>
<p>可惜一般得出结果是<br><img src="/img/2017:11:22_094601.jpeg" alt="outputScreen"><br><strong>分析</strong>：这个命令是静态库使用，动态库并不适用</p>
<h2 id="测试Framework"><a href="#测试Framework" class="headerlink" title="测试Framework"></a>测试Framework</h2><p>使用XCode新建一个动态库<br><img src="/img/2017:11:22_094701.jpeg" alt="newFrameWork"></p>
<p>在 Build Settings 的 Linking 下设置 Mach-O type 为 Dynamic Library<br><img src="/img/2017:11:22_094801.jpeg" alt="settingFrame"></p>
<p>代码也简单加一方法，给外部调用</p>
<p><strong>Test.h</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div></pre></td><td class="code"><pre><div class="line">@interface Test : NSObject</div><div class="line">- (void)helloWorld;</div><div class="line">@end</div></pre></td></tr></table></figure>
<p><strong>Test.m</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div></pre></td><td class="code"><pre><div class="line">- (void)helloWorld {</div><div class="line">NSLog(@"%@", @"Hello, world!");</div><div class="line">}</div></pre></td></tr></table></figure>
<p>通过xcode编译出真机和模拟器的framework<br>这里我把真机的framework文件夹名字命名为iphoneos、模拟器的framework文件夹名字命名为iphonesimulator，注意：这一步很重要；</p>
<h2 id="测试工程"><a href="#测试工程" class="headerlink" title="测试工程"></a>测试工程</h2><p>随便新建一个工程，把两个framework拖入工程，然后删除<strong>LinkFrame works and Librarues</strong>, 然后<strong>Embedded Binaries</strong>再添加两个动态库<br><img src="/img/2017:11:22_094901.jpeg" width="300"></p>
<p>设置如下图设置<br><img src="/img/2017:11:22_095202.jpeg" alt="settingProject2"></p>
<p>最后导入库<br><figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div></pre></td><td class="code"><pre><div class="line">#import <TestFrame/Test.h></div></pre></td></tr></table></figure></p>
<p>调用方法</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div></pre></td><td class="code"><pre><div class="line">Test *test = [[Test alloc] init];</div><div class="line">[test helloWorld];</div></pre></td></tr></table></figure>
<p>编译看看，是不是编译不过，没错，两个库冲突了</p>
<h2 id="冲突处理"><a href="#冲突处理" class="headerlink" title="冲突处理"></a>冲突处理</h2><p>1.删掉其中一个（>-<），废话中的废话</p>
<p>2.共存处理（下面重点介绍）</p>
<h2 id="共存处理"><a href="#共存处理" class="headerlink" title="共存处理"></a>共存处理</h2><p>1.在两个framework的文件夹下建立一个新文件夹，命名为$PLATFORM_NAME,随便将一个framework复制进去<br><img src="/img/2017:11:22_101345.jpeg" alt="settingProject7"></p>
<p>2.将两个framework从工程中删除（逻辑删除），随便讲其中一个拖入工程，注意是拖framework，不是文件夹</p>
<p>3.点击拖入的framework，如图所示，配置路径<br><img src="/img/2017:11:22_095701.jpeg" alt="settingProject3"></p>
<p>4.然后配置<strong>Build Settings</strong>下的Framework Search Paths设置为$PLATFORM_NAME文件夹的路径（路径为红色不要紧）<br><img src="/img/2017:11:22_095801.jpeg" alt="settingProject4"></p>
<p>5.更改选择为$PLATFORM_NAME文件夹下的framework,然后找到改文件夹去改删去该文件夹（你没有看错），是物理删除该文件夹<br><img src="/img/2017:11:22_101645.jpeg" alt="settingProject8"></p>
<p>6.<strong>Embedded Binaries</strong>再添加回$PLATFORM_NAME的framework（路径为浅色不要紧）<br><img src="/img/2017:11:22_095845.jpeg" width="300"></p>
<p>7.基本到这里就可以<br><img src="/img/2017:11:22_095901.jpeg" alt="settingProject6"></p>

<p><strong>1）GCD里面的block</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div></pre></td><td class="code"><pre><div class="line">dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{</div><div class="line">self.name = @"test";</div><div class="line">});</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：GCD是一次性派发的任务，当执行完block,会释放block，GCD本身也释放</p>
<p><strong>2) 属性的block</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">self.propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">self.propertyTest.block = ^{</div><div class="line">self.name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：self->self.propertyTest->block->self.name(self),此情况就是最典型的循环引用了，形成保留环无法释放</p>
<p><strong>3) 属性的block, 增加__weak声明</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div></pre></td><td class="code"><pre><div class="line">self.propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">__weak typeof (self) wealSelf = self;</div><div class="line">self.propertyTest.block = ^{</div><div class="line">typeof(wealSelf) strongSelf = wealSelf;</div><div class="line">strongSelf.name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：self->self.propertyTest->block->self.name(self),但是weak打破了循环，后面那个strongSelf和原来的self并没有直接关系，因为strongSelf是通过weakSelf得来的，而weakSelf又没有强引用原来的self</p>
<p><strong>4) 成员的block</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">self.propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">self.propertyTest.block = ^{</div><div class="line">_name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：self->self.propertyTest->block->_name(self),跟2）上述同理</p>
<p><strong>5) 成员的block,增加__weak声明，但还是用成员</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div></pre></td><td class="code"><pre><div class="line">self.propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">__weak typeof (self) weakSelf = self;</div><div class="line">self.propertyTest.block = ^{</div><div class="line">typeof(weakSelf) strongSelf = weakSelf;</div><div class="line">_name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：self->self.propertyTest->block->_name(self),虽然被weak打破，还是用了self的成员name</p>
<p><strong>6) 属性的block,结束后重置为nil</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div></pre></td><td class="code"><pre><div class="line">self.propertyTest.block = ^{</div><div class="line">self.name = @"test";</div><div class="line">self.propertyTest.block = nil;</div><div class="line">self.propertyTest = nil;</div><div class="line">NSLog(@"%@", self.propertyTest);</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：self->self.propertyTest->block->self.name(self),self.propertyTest = nil,self.propertyTest.block = nil;虽然强制为空，应该是拷贝到堆上的block还没有释放；</p>
<p><strong>7) 临时生成类</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">PropertyTest *propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">propertyTest.block = ^{</div><div class="line">self.name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：propertyTest->block->self.name(self),未形成环,注意：在ARC中，在被拷贝的 block 中无论是直接引用self 还是通过引用self的成员变量间接引用self，该block都会retain self。但是block执行完会释放一次，临时生成的类释放也会在释放一次；</p>
<p><strong>8) 单例持有</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div></pre></td><td class="code"><pre><div class="line">[Singleton sharedSingleton].testBlock = ^{</div><div class="line">self.name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：Singleton 执行完释放一次block, 但是Singleton是单例, 并没有释放;</p>
<p><strong>9) 单例持有,__weak声明</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div></pre></td><td class="code"><pre><div class="line">__weak typeof (self) weakSelf = self;</div><div class="line">[Singleton sharedSingleton].testBlock = ^{</div><div class="line">typeof(weakSelf) strongSelf = weakSelf;</div><div class="line">strongSelf.name = @"test";</div><div class="line">};</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：__weak声明使该block不retain self,Singleton 执行完释放一次block,self也释放了；</p>
<p><strong>10) 单例持有，手动释放</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div></pre></td><td class="code"><pre><div class="line">[Singleton sharedSingleton].testBlock = ^{</div><div class="line">self.name = @"test";</div><div class="line">};</div><div class="line">[Singleton sharedSingleton].testBlock = nil;</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：在ARC中，在被拷贝的 block 中无论是直接引用self 还是通过引用self的成员变量间接引用self，该block都会retain self。但是block执行完会释放一次，然后被手动释放了一次，self也释放了；</p>
<p><strong>11) 数组包含block</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div></pre></td><td class="code"><pre><div class="line">PropertyTest *propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">propertyTest.block = ^{</div><div class="line">self.name = @"test";</div><div class="line">};</div><div class="line"></div><div class="line">self.dataArray = [NSMutableArray array];</div><div class="line">[self.dataArray addObject:propertyTest];</div></pre></td></tr></table></figure>
<p>结果：不执行了dealloc <br><br>分析：self.dataArray -> propertyTest -> block -> self.name ,这是间接持有</p>
<p><strong>12) 数组包含block, __weak声明</strong></p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><div class="line">1</div><div class="line">2</div><div class="line">3</div><div class="line">4</div><div class="line">5</div><div class="line">6</div><div class="line">7</div><div class="line">8</div><div class="line">9</div><div class="line">10</div></pre></td><td class="code"><pre><div class="line">PropertyTest *propertyTest = [[PropertyTest alloc] init];</div><div class="line"></div><div class="line">__weak typeof (self) weakSelf = self;</div><div class="line">propertyTest.block = ^{</div><div class="line">typeof(weakSelf) strongSelf = weakSelf;</div><div class="line">strongSelf.name = @"test";</div><div class="line">};</div><div class="line"></div><div class="line">self.dataArray = [NSMutableArray array];</div><div class="line">[self.dataArray addObject:propertyTest];</div></pre></td></tr></table></figure>
<p>结果：执行了dealloc <br><br>分析：self.dataArray -> propertyTest -> block -> self.name ,这是间接持有, 但被 weak 打破循环</p>

<content type="html"><![CDATA[<h2 id="CABasicAnimation-内存不释放问题"><a href="#CABasicAnimation-内存不释放问题" class="headerlink" title="CABasicAnimation 内存不释放问题"></a>CABasicAnimation 内存不释放问题</h2><p>最近在项目遇到一个问题就是，在页面dismissViewController后发现该页面没有被释放，仔细查阅后，发现页面用了CABasicAnimation的removedOnCompletion = NO会导致不被释放，应该在dismissViewController之前调用removeAnimationForKey</p>
<hr>
<p><strong>原因</strong>：<br>removedOnCompletion 默认为YES，代表动画执行完毕后就从图层上移除，图形会恢复到动画执行前的状态。如果想让图层保持显示动画执行后的状态,那就设置为NO，也就是说图层一直在从而导致图层未释放。</p>
<p><strong>解决</strong>：<br>在界面结束之前先手动调用removeAnimationForKey</p>
