多视图应用程序-使用多个nib

创建的项目是基于windows应用的,在AppDelegate.m中的application加入[self.window  addSubview:switchViewController.view],师程序运行时,加载switchViewController中的视图;

switchViewController作为视图控制类,向其中加入需要切换的视图,构建视图元素.在viewDidLoad中初始化一个视图作为启动程序时显示的视图

[UIView beginAnimations:@"View Flip" context:nil];

[UIView setAnimationDuration:1.25];

[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];

if(self.yellowViewController.view.superview == nil)

{

if(self.yellowViewController == nil)

{

YellowViewController *yellowController = [[YellowViewController alloc]

  initWithNibName:@"YellowView" bundle:nil];

self.yellowViewController = yellowController;

[yellowController release];

}

[UIView setAnimationTransition:

UIViewAnimationTransitionFlipFromRight

  forView:self.view cache:YES];

[blueViewController viewWillAppear:YES];

[yellowViewController viewWillAppear:YES];

[blueViewController.view removeFromSuperview];

[self.view insertSubview:yellowViewController.view atIndex:0];

[yellowViewController viewDidDisappear:YES];

[blueViewController viewDidAppear:YES];

}

视图切换,以及视图切换时的动画效果
