Question

I have this function to write NSData to document dictionary –

- (void)writeData
{
    NSString *str = @"http://labs.widespace.com/resources/banner/ikea/verkligheten/video.m4v";

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:str];
    NSLog(@"%@",path);
    NSLog(@"About to Write Data");
    NSData* data0 = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:str]];
    [data0 writeToFile:path atomically:YES];
    NSLog(@"Writting  Data Completed");
}

Later i read this data and try to play the video using MPMoviePlayerController, but unfortunately this
does not play-

- (void)readData
{
    NSString *str = @"http://labs.widespace.com/resources/banner/ikea/verkligheten/video.m4v";
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,     NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:str];
    NSURL* url = [[NSURL alloc] initFileURLWithPath:path];    
    NSLog(@"url:%@",url);

    NSError *error = nil;
    BOOL isReacahble = [url checkResourceIsReachableAndReturnError:&error];
    NSLog(@"isReachable :%i,%@",isReacahble,error);

    BOOL fileExist =  [[NSFileManager defaultManager] fileExistsAtPath:path];

    if(fileExist)
    {
        NSLog(@"File Exist in path");
    }
    else
    {
        NSLog(@"NO File Exist");
    }

    MPMoviePlayerController *moviePlayer=[[MPMoviePlayerController alloc] initWithContentURL:url];
    [moviePlayer prepareToPlay];
    NSLog(@"movie player:%@",moviePlayer);
    [moviePlayer setControlStyle: MPMovieControlStyleFullscreen];
    [moviePlayer.view setFrame:CGRectMake(0, 0,320, 480)];
    [self.view addSubview:moviePlayer.view];
    moviePlayer.shouldAutoplay = YES;   
    [moviePlayer play];
}

When i try to play this it shows following error-

2013-01-17 11:21:07.067 VideoCheck[338:907] [MPAVController] Autoplay: Disabling autoplay for pause

Can someone please run the code and provide some information about what’s happening here??Please someone help me. I am using iOS 6.

Answer 1

In your wrieData method, instead of giving URL name as file, give only the name of the video. Like

NSString *path = [documentsDirectory stringByAppendingPathComponent:[str lastPathComponent]];

and do the same in readData method too.
