Assertion failure in -[UIApplication _runWithMainScene:transitionContext:completion:],

Question

I am getting the following error in iOS9 only.

Here is my code:-

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDi         


        

Answer 1

here i got the solution by checking if navigationController is nil or not:-

if (self.navigationController== nil)
{
    self.navigationController = [[BufferedNavigationController alloc] initWithRootViewController:self.firstViewController];
}
else
{
    [self.navigationController setViewControllers:@[self.firstViewController] animated:NO];
}
