I'm trying to get a basic .mov video file to play using the code below, but when the button I have assigned the action is pressed, the only thing that shows up is the black frame, but no video is played. Any help is appreciated. Thanks.
@implementation SRViewController
-(IBAction)playMovie{
NSString *url = [[NSBundle mainBundle]
pathForResource:@"OntheTitle" ofType:@"mov"];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc]
initWithContentURL: [NSURL fileURLWithPath:url]];
// Play Partial Screen
player.view.frame = CGRectMake(10, 10, 720, 480);
[self.view addSubview:player.view];
// Play Movie
[player play];
}
@end
Assumed precondition: your project is using ARC.
Your MPMoviePlayerController
instance is local only and ARC has no way of telling that you need to retain that instance. As the controller is not retained by its view, the result is that your MPMoviePlayerController
instance will be released directly after the execution of your playMovie
method execution.
To fix that issue, simply add a property for the player instance to your SRViewController
class and assign the instance towards that property.
Header:
@instance SRViewController
[...]
@property (nonatomic,strong) MPMoviePlayerController *player;

Implementation:

-(IBAction)playMovie
{
NSString *url = [[NSBundle mainBundle]
pathForResource:@"OntheTitle" ofType:@"mov"];
self.player = [[MPMoviePlayerController alloc]
initWithContentURL: [NSURL fileURLWithPath:url]];
// Play Partial Screen
self.player.view.frame = CGRectMake(10, 10, 720, 480);
[self.view addSubview:self.player.view];
// Play Movie
[self.player play];
}
