Question

In a project I’m writing I get this error when I present a new view controller:

Attempt to present…. while a presentation is in progress!

I think it happens because I first present a new view controller, and then in that view I present another view controller.

- (void)loadLabelSettings {
    LabelSettingsViewController *labelSettings = 
      [[LabelSettingsViewController alloc] init];
    labelSettings.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentViewController:labelSettings animated:YES completion:nil];
}

The program doesn’t crash or anything it runs just fine, and there is no errors or warnings in my code. So my question is: Is it something I should be concerned with and if yes how do I solve it?

Thanks in advance 🙂

Answer 1

It is, like you said, probably caused by presenting two view controllers at the same time. Wait with presenting the second view controller until the first one has been fully presented. A good location would be to do this in viewDidAppear.
