changed didselectrow method following:

- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath{ moviepath = [[item objectatindex:indexpath.row]objectforkey:@"link"]; nslog(@"moviepath has %@", moviepath); movieurl = [nsurl urlwithstring:moviepath]; nslog(@"movieurl has %@", movieurl); viewcontroller = [[mpmovieplayerviewcontroller alloc]initwithcontenturl:movieurl]; [self presentmovieplayerviewcontrolleranimated:viewcontroller]; viewcontroller.movieplayer.moviesourcetype = mpmoviesourcetypestreaming; [playercontroller play]; viewcontroller = nil; [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(movieplaybackdidfinish:) name:mpmovieplayerplaybackdidfinishnotification object:viewcontroller]; } - (void) movieplaybackdidfinish:(nsnotification*)notification { viewcontroller = [notification object]; [[nsnotificationcenter defaultcenter] removeobserver:self name:mpmovieplayerplaybackdidfinishnotification object:viewcontroller]; if ([viewcontroller respondstoselector:@selector(setfullscreen:animated:)]) { [viewcontroller.view removefromsuperview]; } }

now, on selecting row blank screen coming , application gets stuck there. video not played

any help in regard appreciated.

thanks in advance.

by looking @ code can tell you dont have reallocate item object.

if have allocated item object somewhere in class , stored values in not reallocate 1 time again did here:

item = [[nsmutablearray alloc]init]; nsstring *moviepath = [item objectatindex:indexpath.row];

by reallocating allocating new memory , in new memory there no objects present.
