UIAlertController showing with delay

Question

I\'m experiencing a problem with UIAlertController on my app now migrated to iOS8 with Date Picker inside.

Below is the code.

UIAlertController *AlertVie         


        

Answer 1

I was having the same issue with a UIAlertController presented by selecting a row from a UITableView. The first time everything worked fine, and then when the user triggered the alert again there was a few seconds delay before the alert was actually presented.

As a workaround I used GCD:

    dispatch_async(dispatch_get_main_queue(), ^{
        [self presentViewController:AlertView animated:YES completion:nil];
    });

It is probably a bug since -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath is already executed on the main thread.

I submitted a bug report to Apple: rdar://19285091
