UIDynamicAnimator - 不会UIView的工作，但将与Self.View？

问题描述

我使用苹果的示例应用程序这个code和它调整到我的。我想要的UIImageView gameOverFalling 运行此方法（反弹的下跌及实物为准）。它应该与UIView的 finalScoreView 碰撞，你可以在网上看到2

   - （无效）{gameOverFallingMethod
    UIDynamicAnimator *动画= [[UIDynamicAnimator页头​​] initWithReferenceView：finalScoreView];    UIGravityBehavior * gravityBeahvior = [[UIGravityBehavior页头] initWithItems：@ self.gameOverFalling]];
    [动画addBehavior给：gravityBeahvior];    UICollisionBehavior * collisionBehavior = [[UICollisionBehavior页头] initWithItems：@ self.gameOverFalling]];
    //苹果说：从创建动态动画的的边界碰撞边界
    //引用视图（self.view）。
    collisionBehavior.translatesReferenceBoundsIntoBoundary = YES;
    collisionBehavior.collisionDelegate =自我;
    [动画addBehavior给：collisionBehavior];    self.animator =动画师;
}
 

然而，当我跑我的应用程序，它返回一个线程1：SIGABRT错误。在控制台：

It works when I replace 'finalScoreView' on line 2 with 'self.view', but then it falls to the bottom of the whole screen.

Any ideas what I did wrong? I would love to know, thanks!

解决方案

It appears from the exception that self.gameOverFalling does not descend from finalScoreView in your view hierarchy. See the quote from UIDynamicAnimator class reference:
