[self.window makeKeyAndVisible]; exception

Question

我的应用程序抛出异常[self.window-makeKeyAndVisible]；应用内委派。

   //获取信息
   [PHTBannerManager getBannerdataWithSuccess:nil];
    //设置window
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.masterVC = [PHTMasterViewController new];
    self.window.rootViewController = _masterVC;
    //启动视频
    [self showMoviePlayer];
    [self.window makeKeyAndVisible];

如果使用XIB ，请替换此行

self.masterVC = [PHTMasterViewController new];

带有

self.masterVC  =  [[PHTMasterViewController alloc] initWithNibName:@"PHTMasterViewController" bundle:nil];
