應用程序窗口預計將有在應用程序啓動的結束（iPhone應用程序）根視圖控制器

Question

我試着做一個iPhone應用程序爲我的課程，並即時得到錯誤

2015-06-26 00:41:31.721 My Movies[3313:6954045] Application windows are expected to have a root view controller at the end of application launch 

即時通訊目前流失的Xcode 6.3.2（6D2105）

這是我的AppDelegate.m完成啓動選項部分看起來像

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    self.window = [[UIWindow alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; 
    // Override point for customization after application launch. 
    self.window.backgroundColor = [UIColor blackColor]; 

    // Create Film TableView and add it to Navigation Controller, then add Nav'Controller to Window 
    FilmTableTableViewController *vc = [[FilmTableTableViewController alloc] initWithStyle:UITableViewStylePlain]; 
    navController = [[UINavigationController alloc] initWithRootViewController:vc]; 
    [[self window] addSubview:[navController view]]; 

    [self.window makeKeyAndVisible]; 
    return YES; 

Answer 1

不要添加navcontroller作爲一個子視圖。 用

代替

// [[self window] addSubview:[navController view]]; 
[self.window setRootViewController:navController];
