我使用下面的代码进行触摸结束。在移动了一些 uiview 之后，我在我的代码中调用了一个 segue，如下所示： [self performSegueWithIdentifier: @"segueToLevel2" sender: self]

segue 的过渡类型设置为“交叉溶解”。

使用下面的代码，一切正常，直到我达到第 5 级。在第 5 级，当调用 segue 时，它​​会进行角到角翻转而不是交叉溶解，从这一点开始，我的应用程序中的每个 segue 都会进行此翻转而不是什么他们打算这样做。如果我拿出我的触摸结束方法，一切都会按预期工作，所以问题一定就在这里。我只是想不通为什么这适用于 1-4 级，但在 5 级上无效。任何帮助将不胜感激......我在这里失去了理智。

我仍然不确定是什么导致了上述代码出现问题，但我找到了一种解决方案，可以重写我的代码并使用 UIPanGestureRecognizer，如下面的每个部分所附。这在整个过程中都非常有效。

- (void) dragGesture5:(UIPanGestureRecognizer *) panGesture {
CGPoint translation = [panGesture translationInView:self.view];

switch (panGesture.state) {
    case UIGestureRecognizerStateBegan:{

        originalCenter = piece5.center;
        [self.view bringSubviewToFront:piece5];


    }
        break;
    case UIGestureRecognizerStateChanged:{

        piece5.center = CGPointMake(piece5.center.x + translation.x,
                                     piece5.center.y + translation.y);
        [self checkColision];


    }
        break;
    case UIGestureRecognizerStateEnded:{            

        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDuration:1.0];
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
        piece5.center = originalCenter;
        [UIView commitAnimations];




    }
        break;
    default:
        break;
}

[panGesture setTranslation:CGPointZero inView:self.view];
}
