通过删除一个UIView创建幻灯片动画，然后添加另一个UIView

Question

我有视图，有一个webview和一个UIToolbar。

我想创建一个动画，执行“kCATransitionFromTop”转换，方法是首先删除先前的webview，然后将新的webView添加到superView。 在此过渡期间，我希望工具栏保留现在的位置，而不是移动。

代码： 添加工具栏

toolbar = [[UIToolbar alloc] init]; 
toolbar.barStyle = UIBarStyleDefault; 
toolbar.tintColor = [UIColor blackColor]; 
[toolbar setFrame:CGRectMake(0, 480 - 88 - 20, 320.0, 44)]; 
//Add the toolbar as a subview to the navigation controller. 
[self.view addSubview:toolbar]; 

动画：

UIView *currentView = webView; 
UIView *theWindow = [currentView superview]; 

UIView *newView = [[UIWebView alloc] initWithFrame: CGRectMake(0, 0, 320, self.view.bounds.size.height - self.navigationController.toolbar.frame.size.height)]; 
newView.backgroundColor = [UIColor whiteColor]; 

// remove the current view and replace with new view 
[currentView removeFromSuperview]; 
[theWindow insertSubview:newView belowSubview:toolbar]; 

// set up the animation 
CATransition *animation = [CATransition animation]; 
[animation setDuration:0.4]; 
[animation setType:kCATransitionPush]; 
[animation setSubtype:kCATransitionFromTop]; 
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; 

[[theWindow layer] addAnimation:animation forKey:@"PushNextArticleView"]; 

一切似乎摸出OK，工具栏除了与web视图移动，以及... 我是怎么做错了，我该如何解决这个问题？

Answer 1

难道你不是故意只适用于的转换newView？

[[newView layer] addAnimation:animation forKey:@"PushNextArticleView"];
