Answer 1

試試這個刪除導航欄。

(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; 
} 

Answer 2

設置navigationBarHidden屬性以隱藏導航條。有關參考，請參閱UINavigationController文檔。

將以下語句添加到您的didFinishLaunchingWithOptions方法中。

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