尽管资料很多，但初学，有点看不懂，以下是我自己的实现方法。
我实现的目标是从testOneViewcontroller.xib点机按钮跳转到界面TwoViewController.xib界面。首先是testOneAppDelegate（即MainWindwo.xib界面）委托给testOneViewcontroller.xib界面显示，testOneViewcontroller.xib中有按钮，按钮方法如下
- (IBAction)button1:(id)sender{ TwoViewController *tempTwoViewController = [[TwoViewController alloc] initWithNibName:@"TwoViewController" bundle:nil]; [self.view.superview addSubview:tempTwoViewController.view];[self.view removeFromSuperview]; [tempTwoViewController release];}
