Unbalanced calls to begin/end appearance transitions for

Question

I have this problem when I simulate my app, its not an error or a warning but it appears in my console, has anyone ever experienced this before?

Answer 1

In my case I was fetching NSData from NSURL inside 'viewDidLoad' method.

Answer 2

I got this issue because I was calling a UIPrintInteractionController from a viewController without UITabbar, and neither UINavigationBar. It seems that the UIPrintInteractionController didn't get the correct printInteractionControllerParentViewController. Implementing the method in the delegate and return the current rootViewController worked for me.

    - (UIViewController*)printInteractionControllerParentViewController:(UIPrintInteractionController*)printInteractionController;

Answer 3

The situation can occur if you are adding a view with a modal view controller as a sub view. Best to use:

-(void) viewDidAppear:(BOOL)animated {
    [self presentViewController:self.yourModalVC animated:YES completion:nil];
}

It is basically saying the view life cycle is not streamlined for those viewControllers you are trying to display then.

Answer 4

I have the similar problem when trying to do:

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:2] animated:YES];

in a function like - (void) popUpToLevelTwo; , and to put a return; at the end of function solves the problem

Answer 5

one solution would be,

[NSTimer scheduledTimerWithTimeInterval:0.05(or as required) target:self
selector:@selector(your_selector_method_to_push_the_view) userInfo:nil repeats:NO];

Answer 6

For what it's worth, I got this same error when not including a call to [super viewDidLoad:animated] in my viewDidLoad override.
