Need to stop reading

[Parkyprg]

Good job with this reader.

However, there only a method to start reading, but not to stop.
I am using it in a UITabBarController and if I change the tab, it will still read. I need to stop it when the view disappears.

Thank you

Thank you for using my framework.

You need to remove [qrCodeView startReading]; method from "M2" QRCodeReaderDelegate method.

i.e.
`- (void)getQRCodeData:(id)qRCodeData {
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"QR Code" message:qRCodeData preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"Close" style:UIAlertActionStyleDefault handler:nil];
[alertController addAction:cancel];

UIAlertAction *reScan = [UIAlertAction actionWithTitle:@"Rescan" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {

[qrCodeView startReading]; // Remove this line

}];
[alertController addAction:reScan];
[self presentViewController:alertController animated:YES completion:nil];
}`

When the view disappears you need to put this code
qrCodeView = nil;

If you still facing any issue or any scenario please let me know,
Thank you.

Thank you for your reply. However, this is not helping too much.
Consider this scenario:
I have a UITabBarController and one of the UIViewControllers have this QRCode reader.
If I switch between controllers, I have to stop reading codes, otherwise, even if the page is not active, the codes are still scanned.

I got this working by destroying the component when the view will disappear.

But unfortunately I had to use a different framework, because this was build only for arm64 architecture and I needed for armv7 and armv7s too and there was no reply from your side for some time.
