iPhone开发 No IB 跳转页面


1.在AppDelegate.m实现的事件代码，用UINavigationController来进行页面之间的切换
 
- (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 来切换view
对应的按钮事件
-(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:@"第一视图"];
 
second *secondViewController = [[second alloc] initWithNibName:nil bundle:nil];
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController:secondViewController];
    [secondNavigationController setNavigationBarHidden:YES animated:YES];
    [secondNavigationController setTitle:@"第二视图"];
   
    third *thirdViewController = [[third alloc] initWithNibName:nil bundle:nil];
UINavigationController *thirdNavigationController = [[UINavigationController alloc] initWithRootViewController:thirdViewController];
    [thirdNavigationController setNavigationBarHidden:YES animated:YES];
    [thirdNavigationController setTitle:@"第三视图"];
   
    forth *forthViewController = [[forth alloc] initWithNibName:nil bundle:nil];
UINavigationController *forthNavigationController = [[UINavigationController alloc] initWithRootViewController:forthViewController];
    [forthNavigationController setNavigationBarHidden:YES animated:YES];
    [forthNavigationController setTitle:@"第四视图"];
 
tabBarController.viewControllers = [NSArray arrayWithObjects:firstNavigationController,secondNavigationController,thirdNavigationController,forthNavigationController,nil];
tabBarController.modalTransitionStyle=UIModalTransitionStyleCoverVertical;      
   
    [selfpresentModalViewController:tabBarController animated:YES];
    }
