ios - Call MPMoviePlayerViewController in app delegate -

i using story board in app. using storyboard views connected new thing want is,

when splash screen goes down, want show 3 sec video every time user opens app.

i know how load video viewcontroller, following code used launch video.

- (void)showvideo {     [super viewdidload];     // additional setup after loading view.      nsstring *path = [[nsbundle mainbundle] pathforresource:@"video" oftype:@"mp4"];     nsurl *url = [nsurl fileurlwithpath:path];     nslog(@"video path :- %@",url);     videocontroller = [[mpmovieplayerviewcontroller alloc] initwithcontenturl:url];     videocontroller.movieplayer.controlstyle = mpmoviecontrolstylenone;     [self presentmovieplayerviewcontrolleranimated:videocontroller];     [videocontroller.movieplayer play];     [[nsnotificationcenter defaultcenter] addobserver:self                                              selector:@selector(movieplaybackdidfinish:)                                                  name:mpmovieplayerplaybackdidfinishnotification                                                object:videocontroller]; }  - (void) movieplaybackdidfinish:(nsnotification*)_notification {     [[nsnotificationcenter defaultcenter] removeobserver:self                                                     name:mpmovieplayerplaybackdidfinishnotification                                                   object:nil];      [videocontroller.view removefromsuperview];     [videocontroller.movieplayer stop];     videocontroller = nil;     [self.view removefromsuperview]; } 

but when use code in rootviewcontroller app crashes saying

attempt present <mpmovieplayerviewcontroller:> on <dashbaordvc:> view not in window hierarchy 

but when use same code in other demo app using navigation controller (no storyboard) works fine. in app story board used, crashes.

also tried

[self.navigationcontroller pushviewcontroller:self.videocontroller animated:no]; 

then thought of adding code in appdelegate file , calling method applicationdidfinishlaunching

but didn't help. can guide me.... same how add mpmovieplayerviewcontroller in app delegate.

i think can mpmovieplayercontroller. try following code

         nsstring *path = [[nsbundle mainbundle] pathforresource:@"video" oftype:@"mp4"];          nsurl *url = [nsurl fileurlwithpath:path];          videoplayer = [[mpmovieplayercontroller alloc] init];         [videoplayer.view setframe:cgrectmake(0.0, viewtopbar.frame.size.height,[uiscreen mainscreen].bounds.size.width, [uiscreen mainscreen].bounds.size.height - (viewtopbar.frame.size.height + 50.0))];                 [videoplayer setmoviesourcetype:mpmoviesourcetypefile];          [videoplayer setcontenturl:url];         [videoplayer setcontrolstyle:mpmoviecontrolstyleembedded];         [videoplayer setscalingmode:mpmoviescalingmodenone];         [videoplayer preparetoplay];         [[nsnotificationcenter defaultcenter] addobserver:self                                              selector:@selector(movieplaybackdidfinish:)                                                  name:mpmovieplayerplaybackdidfinishnotification                                                object:videoplayer];         [self.view addsubview:videoplayer.view];        [videoplayer play]; 

and if dont want full screen used this

[videoplayer setcontrolstyle:mpmoviecontrolstylenone];
