ios - Get Local Document Video File but Black screen come again -

    nsarray *paths =  nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes);     nsstring *documentsdirectory = [paths objectatindex:0];     nsstring *pathvideo = [documentsdirectory stringbyappendingpathcomponent:@"myvideo.mp4"];          nsurl *movieurl = [nsurl fileurlwithpath:pathvideo];     self.movieplayer = [[mpmovieplayercontroller alloc] init];     [self.movieplayer setshouldautoplay:yes];     [self.movieplayer setcontenturl:movieurl.absoluteurl];     [self.movieplayer setmoviesourcetype:mpmoviesourcetypefile];     [self.movieplayer setcontrolstyle:mpmoviecontrolmodedefault];     [self.movieplayer setfullscreen:no];     [self.movieplayer setscalingmode:mpmoviescalingmodenone];     self.movieplayer.view.frame = cgrectmake(40, 40, 240, 350);     [self.view addsubview:self.movieplayer.view];     [self.movieplayer preparetoplay];     [self.movieplayer play]; 

let's try:

nsarray *paths =  nssearchpathfordirectoriesindomains(nsdocumentdirectory,       nsuserdomainmask, yes); nsstring *documentsdirectory = [paths objectatindex:0]; nsstring *pathvideo = [documentsdirectory stringbyappendingpathcomponent:@"myvideo.mp4"]; bool isexisted = [[nsfilemanager defaultmanager] fileexistsatpath:pathvideo]; // sure isexisted yes == file existed @ path 

i try , works, can play videos.
