Answer 1

试试这个删除导航栏。

(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 
{ 
    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; 
    // Override point for customization after application launch. 
    MasterViewController *masterViewController = [[[MasterViewController alloc] initWithNibName:@"MasterViewController" bundle:nil] autorelease]; 
    self.window.rootViewController = masterViewController; 
    [self.window makeKeyAndVisible]; return YES; 
}

设置navigationBarHidden属性以隐藏导航条。有关参考，请参阅UINavigationController文档。

将以下语句添加到您的didFinishLaunchingWithOptions方法中。

[self.navigationController setNavigationBarHidden:YES animated:YES];
