我有一个非常小的动画，我想通过使用块（而不是动画标题）移动视图的框架来完成。
我的视图层次结构非常大，所以我将解释我想要动画的特定视图的所有内容。
最大的视图是占据整个屏幕的视图，因此它是 320x480 点。在这个视图中，我有另一个名为“keypadContainerView”的视图，它是 320x200 点，位于 0, 261，它出现在屏幕底部。这个keypadContainerView 有一个叫做keypadView 的子视图，它有一堆小按钮作为子视图。
最大视图 -> KeypadContainerView -> keypadView -> UIbuttons。
截图：
虽然这不言而喻，那里的键盘是 keypadContainerView，而不是 keypadView 和按钮。我需要这种层次结构，因为我的目标是在这里吸引眼球，并且每一层都有不同的背景。
我创建和处理该视图的方式在这里：
keypadViewContainer = [[[UIView alloc] initWithFrame:CGRectMake(0, 261, 320, 200)] autorelease]; //(Original is 0, 261, 320, 200)
keypadView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 200)];
[keypadViewContainer addSubview:keypadView];
//Add the buttons
[self.view addSubview:keypadViewContainer];
这就是我试图为它制作动画的方式：
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[UIView animateWithDuration:5.0 animations:^{
self.keypadViewContainer.frame = CGRectMake(0, 0, 320, 200);
} completion:NULL];
}
有趣的是，如果我 NSLog 动画中的某些内容：参数，我实际上会得到一些输出，所以该方法肯定会被调用。它根本没有动画任何东西。

我有一种小小的感觉，这可能与我处理观点的方式有关，所以这里有完整的源代码。
对此的任何帮助将不胜感激。
