[avplayerviewcontroller setplayer:]: unrecognized selector sent instance 0x101b91980 error.

i trying play video using avplayerviewcontroller.

@property (nonatomic) avplayer *avplayer; @property (nonatomic) avplayerviewcontroller* avplayerview;  nsstring *path = [[nsbundle mainbundle] pathforresource:@"samplevideo_1280x720_1mb" oftype:@"mp4"];  nsurl *url = [[nsurl alloc] initfileurlwithpath: path];  avasset *asset = [avurlasset urlassetwithurl:url options:nil]; avplayeritem *anitem = [avplayeritem playeritemwithasset:asset];  _avplayer = [avplayer playerwithplayeritem:anitem]; [avplayer addobserver:self forkeypath:@"status" options:0 context:nil]; self.avplayerview = [[avplayerviewcontroller alloc] init]; self.avplayerview.view.frame = self.view.bounds; [self.avplayerview setplayer:_avplayer]; [self.view addsubview:_avplayerview.view];

but crashing. if use same code in new project, video play nicely.what problem?please help.

make sure import avfoundation/avfoundation.h , avkit/avkit.h in controller , try assign player playercontroller this. 

self.avplayerview.player = self.avplayer;

instead of adding observer avplayer class add observer avplayer instance.

[avplayer addobserver:self forkeypath:@"status" options:0 context:nil];
