objective-c - CATransition 的 ios 代码仅在第一次工作？

Question

我使用此代码在 ios sdk 中从一个视图转换到另一个视图，但它只在第一次工作，当我返回到前一个视图时它不起作用，尽管代码被触发......

UIView *currentView = self.viewController1.view;

// get the the underlying UIWindow, or the view containing the current view view
UIView *theWindow = [currentView superview];

// remove the current view and replace with myView1
[currentView setHidden:TRUE];//hide previous view diladi to tabviewcontroller
self.viewController1=[[MyFriendProfile alloc] initWithNibName:@"MyFriendProfile" bundle:nil];
[theWindow addSubview:self.viewController1.view];
[currentView setHidden:FALSE]; 
// set up an animation for the transition between the views
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

[[theWindow layer] addAnimation:animation forKey:@"SwitchToView2"];

任何帮助表示赞赏！

我在这里找到了答案是代码...

//获取viewcontroller1视图

UIView *currentView = self.viewController1.view;

// get the the underlying UIWindow, or the view containing the current view view
UIView *theWindow = [currentView superview];

// remove the current view and replace with myView1
[currentView setHidden:TRUE];//hide previous view diladi to tabviewcontroller


MyFriendProfile *test1=[[MyFriendProfile alloc] initWithNibName:@"MyFriendProfile" bundle:nil];


[theWindow addSubview:test1.view];


// set up an animation for the transition between the views
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

[[theWindow layer] addAnimation:animation forKey:@"SwitchToView1"];
