Mediaplayer framework crashing

AlanR917 · September 2012

Here is my code for a movie player, I have about 20 of these:

//
//  TurnerViewController.m
//  LYWAM Tour
//
//  Created by Alan Raff on 9/13/12.
//
//

#import "TurnerViewController.h"
#import <MediaPlayer/MediaPlayer.h>

@interface TurnerViewController ()

@end

@implementation TurnerViewController
@synthesize biaPlayer16;

-(void)biaVideo16
{
    NSURL *url11 = [NSURL fileURLWithPath:[[NSBundle mainBundle]
                                           pathForResource:@"Turner" ofType:@"mp4"]];
    biaPlayer16 =  [[MPMoviePlayerController alloc]
                    initWithContentURL:url11];
    
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(moviePlayBackDidFinish:)
                                                 name:MPMoviePlayerPlaybackDidFinishNotification
                                               object:nil];
    
    biaPlayer16.controlStyle = MPMovieControlStyleDefault;
    biaPlayer16.shouldAutoplay = YES;
    [self.view addSubview:biaPlayer16.view];
    [biaPlayer16 setFullscreen:YES animated:YES];
}

-(void) moviePlayBackDidFinish:(NSNotification *)aNotification{
    [biaPlayer16.view removeFromSuperview];
    biaPlayer16 = nil;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
	// Do any additional setup after loading the view.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

@end

But every other time I press the "watch" button the app crashes, it doesnt do this on the simulator, only on the actual device. Any ideas?

What's the crash log in the console when it happens? And you may want to unregister from the MPMoviePlayer notification once it's done playing. And how do you initialize and get rid of this controller? Also, why do you have 20 of them?

I have 20 of them because I am playing different videos in different views, I have a tableview that performs a segue to another view, then you have the option to press "watch" and it plays a video. It doesnt have a crash log in the output window, it just goes back to the home screen.

I haven't worked with segues so I'm not sure, but there must be some code that's loading/presenting this view controller and removing it. Are these different videos playing at the same time? If not, you need only one view controller, just don't hardcode the video path/filename in it but feed it from the view controller that's creating it, based on the tableview selection.

Would it be easier if I uploaded the app so you could take a look at it? the videos arent playing at the same time, but I need different viewcontrollers, because they are all different. Here is the code I am using to present the view controller after you press a button on the tableview:

 if(indexPath.row==15){
        [self performSegueWithIdentifier:@"Turner" sender:self];
    }

In what way are they different?

They all display different information, different labels, pictures, and videos

Howdy, Stranger!
