我遇到的问题是，当我通过App Store下载应用程序时，我正在使用MPMoviePlayerViewController播放的MP4正在崩溃我的应用程序。当通过xcode在设备上运行时，通过xcode在设备上运行，以及通过Test Flight安装在设备上时，同样的视频和相同的构建可以正常运行。
我已确认MP4文件包含在Build Phases中 - ＆gt;复制捆绑资源。
我对xCode比较陌生，但是我已经看过崩溃报告，我相信我正在使用的fileURLWithPath存在问题，但是因为除了最后一次在App Store上以外它可以在任何地方工作，我是无法弄清楚我哪里出错了。
以下是我用于显示视频的代码：
- (void)tappedInToolbar:(ReaderMainToolbar *)toolbar videoButton:(UIButton *)button {
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:@"Welcome-Crossings" ofType:@"mp4"]];
MPMoviePlayerViewController *playercontroller = [[MPMoviePlayerViewController alloc]
initWithContentURL:url];
[self presentMoviePlayerViewControllerAnimated:playercontroller];
playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[playercontroller.moviePlayer play];
playercontroller = nil;
}
以下是崩溃报告：
