iOS8：无法在iOS8中添加/显示子视图控制器视图

Question

I have a strange problem particularly in iOS8. I have a view controllers which shows content that came from other view controllers. This is what I am currently doing:

     ViewController *childViewController = [[ViewController alloc] initWithNibName:@"PatientDetailsView" bundle:nil];
    [childViewController setPatient:patient];

   [self.view addSubview:patientDetailsViewController.view];

This above line of code runs fine on devices prior to iOS8 but on iOS8 application got stuck on addSubView method and no exception has been thrown by the compiler.

I am not using storyboard in my project so cannot use container view controller to add a child view controller.

Answer 1

try this code

ViewController *childViewController = [[ViewController alloc] initWithNibName:@"PatientDetailsView" bundle:nil]; [self addChildViewController:childViewController]; [self.view addSubview:childViewController.view]; [childViewController didMoveToParentViewController:self];

Hope this helps.
