關於iOS uinavigationcontroller及Uitabbarcontroller知識的梳理

一、導航UINavigationController

導航到一個controller：

 [navigateController pushViewController:loginView animated:YES];

返回到上頁的代碼：

 [self.navigationController
popViewControllerAnimated:YES];

返回到根的代碼：

 [self.navigationController popToRootViewControllerAnimated:<#(BOOL)#>]

返回固定view的代碼：

   [self.navigationController popToViewController:<#(UIViewController *)#> animated:<#(BOOL)#>:<#(BOOL)#>]

範例程式碼：

 代碼例子一

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions

{

    self.window = [[[UIWindow
alloc] initWithFrame:[[UIScreen
mainScreen] bounds]]
autorelease];

    // Override point for customization after application launch.

    LoginViewController  *loginView=[[LoginViewController
alloc] init];

    loginView.title=@"使用者登陸";

    UINavigationController* navigateController=[[UINavigationController
alloc]init];

    [navigateController
pushViewController:loginView
animated:YES];

    [self.window
addSubview:navigateController.view];

    self.window.backgroundColor = [UIColor
whiteColor];

    [self.window
makeKeyAndVisible];

    return
YES;

}

二、Uitabbarcontroller知識的梳理

代碼例子二

-(void) onLogin:(id)sender

{

   

    UITabBarController* tabController=[[UITabBarController
alloc]init];

    InfoViewController* info=[[InfoViewController
alloc]init];

    info.title=@"話費查詢";

    UINavigationController* infoNav=[[UINavigationController
alloc]init];

    [infoNav pushViewController:info
animated:YES];

    

    

    UINavigationController* indexNav=[[UINavigationController
alloc]init];

    indexViewController* indexController=[[indexViewController
alloc]init];

    indexController.title=@"拜佛系統";

    [indexNav
pushViewController:indexController
animated:YES];

    

    tabController.viewControllers=[NSArray
arrayWithObjects:indexNav,infoNav,
nil];

    [self
presentModalViewController:tabController
animated:YES];

            

}

代碼例子一二的如下：
