我正在尝试在 ios 中播放电影，但我不断收到错误消息。
我的代码：
-(IBAction)playMovie:(id)sender
NSString *filepath = [[NSBundle mainBundle] pathForResource:@"big-buck-bunny-clip" ofType:@"m4v"];
NSURL *fileURL = [NSURL fileURLWithPath:filepath];
MPMoviePlayerController *moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[self.view addSubview:moviePlayerController.view];
moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
- (void)moviePlaybackComplete:(NSNotification *)notification
MPMoviePlayerController *moviePlayerController = [notification object];
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:moviePlayerController];
[moviePlayerController.view removeFromSuperview];
[moviePlayerController.view setFrame:CGRectMake(38, 100, 250, 163)];
[self.view addSubview:moviePlayerController.view];
//moviePlayerController.fullscreen = YES;
[moviePlayerController play];
}
错误是：
由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：“*** -[NSURL initFileURLWithPath:]: nil string parameter”
