视图控制器过渡

Question

我有代码：

ListViewController * listViewController = [[ListViewController alloc] initWithNibName:@"ListViewController" bundle:nil];  

[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:1.5]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; 
[self viewWillDisappear:YES]; 
[listViewController viewWillAppear:YES]; 

self.view.hidden = YES; 
listViewController.view.hidden = NO; 


[self viewDidDisappear:YES]; 
[listViewController viewDidAppear:YES]; 
[UIView commitAnimations];  

但它没有作品，listViewController不显示（请，有人可以告诉我这个问题的解决方案

Answer 1

试着这么做：

UIViewAnimationOptions ops = UIViewAnimationOptionTransitionFlipFromRight; 
NSArray *temp = [[NSBundle mainBundle] loadNibNamed:@"NameOfNib" owner:self options:nil]; 
UIView* newView = [[temp objectAtIndex:0] view]; 
[UIView transitionFromView:self.view toView:newView duration:1.5 options:ops completion:nil]; 
self.view = newView; //Lets you control the new view from the current controller (you might want to save a reference to the old one if you need to change back) 

正如meronix所说，苹果公司不鼓励非基于块的动画用于较新的iOS版本。上述方法是“批准”的方式。

就这么你知道，viewWillAppear,viewDidDisappear和类似的方法不是你调用来使视图做事情的方法。发生这些事情时会自动调用它们。

你的代码有一些误解;我在下面评论过他们

//This looks fine (depending on what is in the nib) 
ListViewController * listViewController = [[ListViewController alloc] initWithNibName:@"ListViewController" bundle:nil]; 

//Normally I use these to move things around, not change the view 
[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:1.5]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; 

[self viewWillDisappear:YES]; //These two methods aren't things that you call 
[listViewController viewWillAppear:YES]; 

self.view.hidden = YES; //If you're flipping or otherwise moving a view out of 
listViewController.view.hidden = NO; //sight then you don't need to hide/unhide views 

[self viewDidDisappear:YES]; //Same as above, you don't call these 
[listViewController viewDidAppear:YES]; 
[UIView commitAnimations];

删除不必要的代码，只是写？这...

ListViewController * listViewController = [[ListViewController alloc] initWithNibName:@"ListViewController" bundle:nil];  
[UIView beginAnimations:nil context:nil]; 
[UIView setAnimationDuration:1.5]; 
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; 
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; 
[self.view addSubview:listViewController.view]; 
[UIView commitAnimations];

它不能工作！

您只需创建并分配一个UIViewController，但绝不会将它推到任何堆栈上，或将其视图添加到可见视图中。

当您设置listViewController.view.hidden没有，你是不是神奇地显示它在屏幕上：你需要它的视图添加到视图（或窗口），这已经是在屏幕上......

PS beginAnimation已弃用：使用块动画代替...
