MPMoviePlayerViewController无法播放电影，无法立即启动和关闭 [英] MPMoviePlayerViewController won't play movie, start and closes immediately

问题描述

我正在尝试使用MPMoviePlayerViewController播放视频，我展示了MPMoviePlayerViewController，但是1秒钟后他将自己解散了.

I'm trying to play a video with MPMoviePlayerViewController, I present the MPMoviePlayerViewController but after 1 second he is dismissing itself.

这是我的代码:

.h:

#import <MediaPlayer/MediaPlayer.h>

@property (strong, nonatomic) MPMoviePlayerViewController *moviePlayerViewController;

.m:

- (void)playmovie
{
    NSString *databaseName = @"NO.mp4";
    NSArray *documentPaths =
    NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

    NSString *documentDir = [documentPaths objectAtIndex:0];
    NSString *databasePath = [documentDir stringByAppendingPathComponent:databaseName];

    NSURL *movieURL = [NSURL fileURLWithPath:databasePath];

    UIGraphicsBeginImageContext(CGSizeMake(1,1));
    self.moviePlayerViewController = [[MPMoviePlayerViewController alloc] initWithContentURL:movieURL];
    [self presentMoviePlayerViewControllerAnimated:self.moviePlayerViewController];
    UIGraphicsEndImageContext();

    [self.moviePlayerViewController.moviePlayer prepareToPlay];
    [self.moviePlayerViewController.moviePlayer play];
}

请告诉我我做错了.

提前谢谢！
