我正在使用此代码从当前视图转换到另一个视图并且它可以工作。问题是当我尝试返回当前视图时，应用程序崩溃了。

这是我用来从当前视图传递到新视图的代码：

CATransition *transition = [CATransition animation];

transition.duration = 0.75;
// using the ease in/out timing function
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

transition.type = kCATransitionReveal;

transition.subtype = kCATransitionFromRight;

transition.delegate = self;

// Next add it to the containerView's layer. This will perform the transition based on how we change its contents.
[self.view.layer addAnimation:transition forKey:nil];

// Here we hide view1, and show view2, which will cause Core Animation to animate view1 away and view2 in.

self.view.hidden = YES;

MyMessages *info1=[[MyMessages alloc] initWithNibName:@"MyMessages" bundle:nil];
[self.view addSubview:info1.view];

info1.view.hidden = NO;
self.view.hidden = NO;

我尝试使用以下代码返回：

CATransition *transition = [CATransition animation];

transition.duration = 0.75;
// using the ease in/out timing function
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];

transition.type = kCATransitionReveal;

transition.subtype = kCATransitionFromLeft;

transition.delegate = self;

// Next add it to the containerView's layer. This will perform the transition based on how we change its contents.
[self.view.layer addAnimation:transition forKey:nil];

// Here we hide view1, and show view2, which will cause Core Animation to animate view1 away and view2 in.
self.view.hidden = YES;

FirstViewController *info1=[[  FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil];
[self.view addSubview:info1.view];

info1.view.hidden = NO;
self.view.hidden = NO;

UIView这是在aUITabBarController和 new之间进行转换所需的代码UIView。代码转到一个按钮，该按钮IBAction存在UIView于UITabBarController.

//initialize the app delegate

AppDelegate appDelegate = (AppDelegate) [[UIApplication sharedApplication] delegate];

// get the view that's currently showing

UIView *currentView = self.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 mynewView1
[currentView removeFromSuperview];

//assign the new view to the viewcontroller1. It is the first uiviewcontroller of the uitabbarcontroller. My uitabbarcontroller consists of five uiviewcontrollers in my project. The button exists in the first viewcontroller1 this is why i am assigning the new view to the viewcontroller1. If the button was pressed from the secondviewcontroller (viewcontroller2) of my uitabbarcontroller i will assign the new view to the secondviewcontroller (viewcontroller2) and so on...
appDelegate.viewController1=[[MyMessages alloc] initWithNibName:@"MyMessages" bundle:nil];

//add it to the window
[theWindow addSubview:appDelegate.viewController1.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"];

谢谢你的帮助！我已经尝试了一天多来实现它。我希望它能帮助有同样问题的人。
