Warning msg

When I cancel the camera:

Warning: Attempt to present <UIImagePickerController: 0x16dcc590> on <TabBarController: 0x16e96a10> while a presentation is in progress!

Code:

  • (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{ [self dismissViewControllerAnimated:NO completion:nil]; [self.tabBarController setSelectedIndex:0]; }

This message is typically caused when you are trying to display a view controller when a view controller is already in the process of being displayed. You see this when you add code to dismiss or add a view controller, but at the same time it's being handled via the storyboard and a segue tied to a button. Try deleting [self dismissViewControllerAnimated:NO completion:nil]; and see if it gives you the error. If it does, replace it and try deleting [self.tabBarController setSelectedIndex:0]; and see if that's the offending code. You might not need either of those statements.
