在应用程序启动结束时，应用程序窗口应具有一个根视图控制器(Iphone App) [英] Application windows are expected to have a root view controller at the end of application launch (Iphone App)

问题描述

我正在尝试为我的课程制作一个Iphone应用程序，并且收到错误消息

Im trying to make an Iphone app for my coursework and im getting the error

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

我目前正在运行Xcode 6.3.2(6D2105)

Im currently running off Xcode 6.3.2 (6D2105)

这是我的AppDelegate.m完成启动选项部分的样子

This is what my AppDelegate.m finish launching options section looks like

- (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;

推荐答案

不要将navcontroller添加为子视图. 替换为

Don't add the navcontroller as a subview. Replace that with

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