I have a very weird problem with the UINavigationController on iOS 8, maybe someone encountered this already and can shed some light. I have 2 views: let's say view A and view B I am using it like this:
view A [self.navigationController pushViewController:vc animated:YES];
push to a new view B [self.navigationController pushViewController:vc animated:YES];
push to a new view B [self.navigationController pushViewController:vc animated:YES];
push to a new view B [self.navigationController pushViewController:vc animated:YES];
push to a new view B [self.navigationController pushViewController:vc animated:YES];
push to a new view B [self.navigationController pushViewController:vc animated:YES];
return to view A [self.navigationController popToRootViewControllerAnimated:YES];
The problem is that if I play with this for 2 min and go through this like push-push-push-push-pop and again... at some time it stops animating, for either push and pop. I checked the 1) view controllers they get deallocated on the pop to root, 2) I don't receive any memory warnings, 3) the navigation controller is the rootviewcontroller of the window so why this problem?
I can't find any explanation maybe someone has encountered this already. Also I am mentioning I am not using custom animations, just the plain native push and pop of a normal UIViewController, not even subclassing that so everything is plain native.

@ kokos8998尝试使用
@interface AnimatorPushGalleryToGallery : NSObject <UIViewControllerAnimatedTransitioning>
然后在视图A中添加此项并将控制视图B中的所有内容A-&gt; B或B-&gt; A(或者如果您需要更多自定义,则在B中添加相同的委托)
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
self.navigationController.delegate = self;
}
- (nullable id <UIViewControllerAnimatedTransitioning>)navigationController:(UINavigationController *)navigationController
animationControllerForOperation:(UINavigationControllerOperation)operation
fromViewController:(UIViewController *)fromVC
toViewController:(UIViewController *)toVC
{
if(operation == UINavigationControllerOperationPush)
return [AnimatorPushGalleryToGallery new];
else if(operation == UINavigationControllerOperationPop)
return [AnimatorPopGalleryToGallery new];
return nil;
}
