I have a strange visual bug that only affects iOS 9 devices:
My app’s login
I faced this problem about 30 minutes ago.
The UIAlertView has been deprecated since iOS9 was released.
We solved this issue by using the UIAlertController, like this:
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Alert Title!" message:@"This is an alert message." preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]; [alertController addAction:ok]; [self presentViewController:alertController animated:NO completion:nil];
This should fix your problem.
If animated = YES, you may get the same issue as before. This is a bug with iOS9.
Let me know how it goes, and if this fixes your problem.
