I'm getting the following runtime warning due to multiple simultaneous UIAlertControllers presenting at the same time:
Warning: Attempt to present <UIAlertController: 0x1835c000> on <MyViewController: 0x17d26e70> which is already presenting <UIAlertController: 0x18381400>
I know only one alert view controller can be presenting at a time, so the way I thought to serialize execution of each -presentViewController:: is:
dispatch_async( dispatch_get_main_queue(), ^{
[ self presentViewController: alert
animated: YES
completion: nil ];
});
Why isn't dispatch_get_main_queue() enforcing serialized execution? Is there another way to do this?
-Carl
