iOS video not playing with MPMoviePlayer - ios

Question

I'am making video player module for my app.
This is my .h file:
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
#interface SpanishViewController : UIViewController
- (IBAction)Video1Button:(id)sender;
#property (nonatomic, strong) MPMoviePlayerController *moviePlayer;
#end
This is code of event executed by button in .m file:
- (IBAction)Video1Button:(id)sender {
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"01" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
Video encoded in mp4 in accordance with the standards and runs on iOS.
Result is - here
Video does not start, the button "Done" does not work .. I can not understand what went wrong.
Please help me.

Answer 1

Yes, the problem is,
instead of using global property
#property (nonatomic, strong) MPMoviePlayerController *moviePlayer;
you have re-declared a MPMoviePlayerController in your - (IBAction)Video1Button:(id)sender; method.
Because of that, life of the moviePlayer ends with the end of Video1Button method.
correct way,
- (IBAction)Video1Button:(id)sender {
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"01" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
_moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[self.view addSubview:_moviePlayerController.view];
_moviePlayerController.fullscreen = YES;
[_moviePlayerController play];
}

Answer 2

Change your video1Button method like this.
- (IBAction)Video1Button:(id)sender {
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"01" ofType:#"mp4"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[self.view addSubview:self.moviePlayerController.view];
self.moviePlayerController.fullscreen = YES;
[self.moviePlayerController play];
}
