iPad从纵向旋转到横向

Question

我的视图最初是横向模式。当一个按钮被粘贴时，一个视图以纵向模式打开，一切都可以找到。问题是当我从该视图返回到根视图时，视图将无法正确旋转。这是我用来将视图从纵向旋转到横向的代码，

-(void)viewWillDisappear:(BOOL)animated
{
[super viewWillDisappear:animated];

//rotate the page to lansscape
CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(-90*0.0174532925);
landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);

[self.navigationController.view setTransform:landscapeTransform];

self.navigationController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth |UIViewAutoresizingFlexibleHeight;    
self.navigationController.view.frame  = CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height);
self.navigationController.view.center  = CGPointMake (384.0, 544.0);

[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeLeft;
}

这是从纵向页面返回后以横向模式显示根页面的屏幕截图

它应该是这样的样子

-(void)viewWillDisappear:(BOOL)animated
{

[super viewWillDisappear:animated];

//rotate the page to lansscape
CGAffineTransform landscapeTransform = CGAffineTransformMakeRotation(-90*0.0174532925);
landscapeTransform = CGAffineTransformTranslate (landscapeTransform, 0.0, 0.0);

[self.navigationController.view setTransform:landscapeTransform];

self.navigationController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth |UIViewAutoresizingFlexibleHeight;    
self.navigationController.view.frame  = CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height+64);
self.navigationController.view.center  = CGPointMake (384.0, 512.0);

[UIApplication sharedApplication].statusBarOrientation = UIInterfaceOrientationLandscapeLeft;

}

我必须玩的东西来调整在纵向模式下这个视图消失之后出现的横向视图是这样的，

self.navigationController.view.frame  = CGRectMake(0.0, 0.0, self.view.frame.size.width, self.view.frame.size.height+64);
self.navigationController.view.center  = CGPointMake (384.0, 512.0);

我用中心点和框架高度来调整它。
