Hello,
In few words, my application is doing that :
1) My main view (MovieListController) has some video thumbnails and when I tap on one, it displays the moviePlayer (MoviePlayerViewController) :
MovieListController.h :
@interface MoviePlayerViewController : UIViewController <UITableViewDelegate>{
UIView *viewForMovie;
MPMoviePlayerController *player;
}
@property (nonatomic, retain) IBOutlet UIView *viewForMovie;
@property (nonatomic, retain) MPMoviePlayerController *player;
- (NSURL *)movieURL;
@end
MovieListController.m :
MoviePlayerViewController *controllerTV = [[MoviePlayerViewController alloc] initWithNibName:@"MoviePlayerViewController" bundle:nil];
controllerTV.delegate = self;
controllerTV.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: controllerTV animated: YES];
[controllerTV release];
2) In my moviePlayer, I initialize the video I want to play
MoviePlayerViewController.m :
@implementation MoviePlayerViewController
@synthesize player;
@synthesize viewForMovie;
- (void)viewDidLoad {
NSLog(@"start");
[super viewDidLoad];
self.player = [[MPMoviePlayerController alloc] init];
self.player.view.frame = self.viewForMovie.bounds;
self.player.view.autoresizingMask =
UIViewAutoresizingFlexibleWidth |
UIViewAutoresizingFlexibleHeight;
[self.viewForMovie addSubview:player.view];
self.player.contentURL = [self movieURL];
}
- (void)dealloc {
NSLog(@"dealloc TV");
[player release];
[viewForMovie release];
[super dealloc];
}
-(NSURL *)movieURL
{
NSBundle *bundle = [NSBundle mainBundle];
NSString *moviePath =
[bundle
pathForResource:@"FR_Tribord_Surf camp_100204"
ofType:@"mp4"];
if (moviePath) {
return [NSURL fileURLWithPath:moviePath];
} else {
return nil;
}
}
-> It's working good, my movie is display
My problem :
When I go back to my main view :
- (void) returnToMap: (MoviePlayerViewController *) controller {
[self dismissModalViewControllerAnimated: YES];
}
And I tap in a thumbnail to display again the moviePlayer (MoviePlayerViewController), I get a *Program received signal: “EXC_BAD_ACCESS”.*
In my debugger I saw that it's stopping on the thread "main" :
//
// main.m
// MoviePlayer
//
// Created by Eric Freeman on 3/27/10.
// Copyright Apple Inc 2010. All rights reserved.
//
#import <UIKit/UIKit.h>
int main(int argc, char *argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
int retVal = UIApplicationMain(argc, argv, nil, nil); //EXC_BAD_ACCESS
[pool release];
return retVal;
}
If I comment self.player.contentURL = [self movieURL];
it's working, but when I let it, iI have this problem.
I read that it's due to null pointer or memory problem but I don't understand why it's working the first time and not the second time. I release my object in dealloc method.
Thanks for your help !
Bruno.
