自定義Segue動畫顯示黑屏

Question

我遇到了一個新問題，在使用自定義界面顯示destinationViewController ，在過渡期間將源ViewController更改為黑屏，我需要屏幕保持原樣（我的設計）。

UIViewController *sourceViewController = (UIViewController*)[self sourceViewController];
UIViewController *destinationController = (UIViewController*)[self destinationViewController][screenshot][1]

CATransition* transition = [CATransition animation];
transition.duration = 0.1;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
transition.subtype = kCATransitionFromRight; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom


[destinationController.view.layer addAnimation:transition forKey:kCATransition];
[sourceViewController presentViewController:destinationController animated:NO completion:nil];

我認為您需要保留上下文，請嘗試以下操作：

    UIViewController *rootViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
    rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
    UIViewController *destinationController = (UIViewController*)[self destinationViewController]
    [sourceViewController presentViewController:destinationController animated:NO completion:nil];
