CATransition的ios代碼僅在第一次使用？

Question

我使用此代碼在ios sdk中進行從一個視圖到另一個視圖的轉換，但它僅在第一次工作時，當我返回到之前的視圖時，雖然代碼被觸發，但它不起作用...

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"]; 

任何幫助讚賞！

Answer 1

我發現這裏的答案是代碼...

//獲取viewcontroller1視圖

的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"];
