我有一個問題，MPMoviePlayerController [iPhone SDK]

Question

我想創建一個應用程序與電影簡介就像gameloft遊戲。所以當應用程序已經發布時，電影播放良好，但在播放之前..我的FirstViewController xib文件首先顯示電影開始播放！爲什麼？這裏是我的代碼：

- (void)applicationDidFinishLaunching:(UIApplication *)application {  
NSBundle *bundle = [NSBundle mainBundle]; 
    NSString *moviePath = [bundle pathForResource:@"movie" ofType:@"m4v"]; 

    NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; 

    MPMoviePlayerController *IntroMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; 

    IntroMovie.movieControlMode = MPMovieControlModeHidden; 
    [IntroMovie play]; 
}

另一種方法是添加不同的視圖（例如簡單的黑色背景），然後替換它在視頻播放完畢：

- (void)applicationDidFinishLaunching:(UIApplication *)application {  

    NSBundle *bundle = [NSBundle mainBundle]; 
    NSString *moviePath = [bundle pathForResource:@"Hafez-2" ofType:@"mov"]; 
    NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; 


    MPMoviePlayerController *IntroMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; 
    [IntroMovie setOrientation:UIDeviceOrientationPortrait animated:NO]; 
    [IntroMovie play]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlaybackDidFinish:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:nil]; 
    // Create an initial pure black view 
    UIView* blackView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; 
    blackView.backgroundColor = [UIColor blackColor]; 
    [window addSubview:blackView]; // sends [blackView retain] 
    [blackView release]; 
    [window makeKeyAndVisible]; 
} 

- (void) moviePlaybackDidFinish:(NSNotification*)notification 
{ 
    UIView* blackView = [[window subviews] objectAtIndex:0]; 
    [blackView removeFromSuperview]; // sends [blackView release] 
    [window addSubview:viewController.view]; 
} 

讓我知道你是否需要修改後的源代碼，我可以將它發佈到某個地方

您需要等待電影完成播放之前，將第一個視圖作爲子視圖添加到窗口。

這應該可以做到。你的代碼更改爲：

- (void)applicationDidFinishLaunching:(UIApplication *)application {  

    NSBundle *bundle = [NSBundle mainBundle]; 
    NSString *moviePath = [bundle pathForResource:@"Hafez-2" ofType:@"mov"]; 
    NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; 


    MPMoviePlayerController *IntroMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; 
    [IntroMovie setOrientation:UIDeviceOrientationPortrait animated:NO]; 
    [IntroMovie play]; 

    [[NSNotificationCenter defaultCenter] addObserver:self 
              selector:@selector(moviePlaybackDidFinish:) 
               name:MPMoviePlayerPlaybackDidFinishNotification 
               object:nil]; 
} 

- (void) moviePlaybackDidFinish:(NSNotification*)notification 
{ 
    [window addSubview:viewController.view]; 
    [window makeKeyAndVisible]; 
}
