Controller 之间的切换

new_gist_file

DetailController *detailController=[[DetailController alloc] initWithNibName:@"DetailController" bundle:nil];
self.view.window.rootViewController=detailController;

//another:
TwoViewController *tempTwoViewController = [[TwoViewController alloc] initWithNibName:@"TwoViewController"   bundle:nil];
[self.view.superview addSubview:tempTwoViewController.view];
[self.view removeFromSuperview];
[tempTwoViewController release]; 

//方法一右侧进入
[self.navigationController pushViewController:fvc animated:YES];
//返回到上一个
[self.navigationController popViewControllerAnimated:YES];

//另一种方法从下面切入
SecondViewController* svc=[[SecondViewController alloc]init];
[self.navigationController presentModalViewController:svc animated:YES];
[svc release];

//返回到上一个UIViewController
[self.navigationController dismissModalViewControllerAnimated:YES];

//2.如果没有导航栏NavigationController的话 也是可以切换的
SecondViewController* svc=[[SecondViewController alloc]init];
svc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
[self presentModalViewController:svc animated:YES];
[svc release];
//返回到上一个UIViewController
[self dismissModalViewControllerAnimated:YES];

//也可以隐藏导航条，实际有一个 NavigatioController
TRYViewController *controller = [[TRYViewController alloc]init];
    
    UINavigationController *nav = [[TRYNavViewController alloc] initWithRootViewController:controller];
    
    self.window.rootViewController = nav;
    
    //在自定义的 NavigationController 的viewDidLoad 中：
    [self setNavigationBarHidden:YES];
