UINavigationController导航控制器－视图切换

越努力.越幸福.－－－－willingseal.

UINavigationController的结构组成

－－－－－－－－

（1）新建一个工程，创建3个控制器类和3个视图，并关联视图和控制器，设置第一个view为蓝绿色，第二个view为黄色，第三个view为橘色。

（2）

在AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindowalloc] initWithFrame:[[UIScreenmainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColorwhiteColor];


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

self.navController = [[UINavigationControlleralloc] initWithRootViewController:listVC];

[self.windowaddSubview:self.navController.view];


[self.windowmakeKeyAndVisible];
returnYES;
}

（3）点击第一个view中的button进入第二个页面在ListViewController.m
- (void)viewDidLoad
{
[superviewDidLoad];
// Do any additional setup after loading the view.


self.title = @"列表";


}


- (IBAction)push:(id)sender {


TwoViewController *twoVC = [[TwoViewControlleralloc] initWithNibName:@"Two_iphone"bundle:nil];


[self.navigationControllerpushViewController:twoVCanimated:YES];

}
（4）点击第二个view中的button进入第三个页面

在 TwoViewController.m

- (void)viewDidLoad
{
[superviewDidLoad];
// Do any additional setup after loading the view.

self.title = @"Two";
}

- (IBAction)toTwo:(id)sender {

ThreeViewController *threeVC = [[ThreeViewControlleralloc] initWithNibName:@"Three_iphone"bundle:nil];

[self.navigationControllerpushViewController:threeVC animated:YES];


}
