两块不同的缓存,数据粘连

[hanchenhao]

        let cache: Cache = Cache.shareInstance
        cache.set(object: "2222" as NSCoding, forKey: "2223")
        let cache2 = Cache(name: "cache2")

        cache2?.set(object: "1111" as NSCoding, forKey: "1111")
        print(cache.object(forKey: "1111") ?? "none")

输入结果为:1111

It's a good question, it's a bug definitely.
The reason of the problem is that the two cache share one memery cache.
When you call 'Cache(name: "xxx")', actually it just create another 'DiskCache'，but still use the same that 'share memory'.
'Set' and 'Get' methods will prior write and read from memory , it lead to the issue.

If you reboot your app, you will not get the value of key '1111' from share cache until you get value of key '1111' form cache named 'cache2' first time.

BTW, i like your avatar.
