iPhone開發 No IB 跳轉頁面

1.在AppDelegate.m實現的事件代碼，用UINavigationController來進行頁面之間的切換

 

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

{

    self.window =[[UIWindowalloc] initWithFrame:[[UIScreenmainScreen]bounds]];

    self.window.backgroundColor=[UIColorwhiteColor];

    rootView * r=[[rootViewalloc]init];

    UINavigationController * nav=[[UINavigationControlleralloc]initWithRootViewController:r];

    self.window.rootViewController=nav;

    [self.windowmakeKeyAndVisible];

returnYES;

}

2.用tab bar 來切換view

對應的按鈕事件

-(IBAction)btnTab

{

    UITabBarController* tabBarController = [[UITabBarControlleralloc] init];

first *firstViewController = [[first alloc] initWithNibName:nil bundle:nil];

UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController:firstViewController];

    [firstNavigationController setNavigationBarHidden:YES animated:YES];

    [firstNavigationController setTitle:@"第一視圖"];

 

second *secondViewController = [[second alloc] initWithNibName:nil bundle:nil];

UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:secondViewController];

    [secondNavigationController setNavigationBarHidden:YES animated:YES];

    [secondNavigationController setTitle:@"第二視圖"];

   

    third *thirdViewController = [[third alloc] initWithNibName:nil bundle:nil];

UINavigationController *thirdNavigationController = [[UINavigationController alloc] initWithRootViewController:thirdViewController];

    [thirdNavigationController setNavigationBarHidden:YES animated:YES];

    [thirdNavigationController setTitle:@"第三視圖"];

   

    forth *forthViewController = [[forth alloc] initWithNibName:nil bundle:nil];

UINavigationController *forthNavigationController = [[UINavigationController alloc] initWithRootViewController:forthViewController];

    [forthNavigationController setNavigationBarHidden:YES animated:YES];

    [forthNavigationController setTitle:@"第四視圖"];

 

tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigationController,secondNavigationController,thirdNavigationController,forthNavigationController,nil];

tabBarController.modalTransitionStyle=UIModalTransitionStyleCoverVertical;      

   

    [selfpresentModalViewController:tabBarController animated:YES];

    }
