최근에 비슷한 문제가 발생했습니다. UITransitionView문제를 해결하기 위해 창에서 수동으로 제거한 다음 이전 루트 뷰 컨트롤러에서 dismiss를 호출하여 할당 해제되었는지 확인해야했습니다.
수정은별로 좋지는 않지만 질문을 게시 한 이후로 더 나은 방법을 찾지 못한 이상 작동하는 유일한 방법입니다! viewController단지입니다 newController원래 질문에서.
UIViewController *previousRootViewController = self.window.rootViewController;
self.window.rootViewController = viewController;
// Nasty hack to fix http://stackoverflow.com/questions/26763020/leaking-views-when-changing-rootviewcontroller-inside-transitionwithview
// The presenting view controllers view doesn't get removed from the window as its currently transistioning and presenting a view controller
for (UIView *subview in self.window.subviews) {
if ([subview isKindOfClass:NSClassFromString(@"UITransitionView")]) {
[subview removeFromSuperview];
}
}
// Allow the view controller to be deallocated
[previousRootViewController dismissViewControllerAnimated:NO completion:^{
// Remove the root view in case its still showing
[previousRootViewController.view removeFromSuperview];
}];
나는 이것이 당신의 문제를 해결하는 데 도움이되기를 바랍니다. 그것은 엉덩이에 절대적인 고통입니다!

func set(rootViewController newRootViewController: UIViewController, withTransition transition: CATransition? = nil) {
let previousViewController = rootViewController
if let transition = transition {
// Add the transition
layer.add(transition, forKey: kCATransition)
}
rootViewController = newRootViewController

if #available(iOS 13.0, *) {
// In iOS 13 we don't want to remove the transition view as it'll create a blank screen
} else {
// The presenting view controllers view doesn't get removed from the window as its currently transistioning and presenting a view controller
if let transitionViewClass = NSClassFromString("UITransitionView") {
for subview in subviews where subview.isKind(of: transitionViewClass) {
subview.removeFromSuperview()
}
}
}
if let previousViewController = previousViewController {
// Allow the view controller to be deallocated
previousViewController.dismiss(animated: false) {
// Remove the root view in case its still showing
previousViewController.view.removeFromSuperview()
}
}
}
}
용법:
window.set(rootViewController: viewController)
또는
let transition = CATransition()
transition.type = kCATransitionFade
window.set(rootViewController: viewController, withTransition: transition)
