我修改你的代码就可以了：

NSURL *url = [NSURL URLWithString:@"http://54.254.248.1/app/webroot/uploads/question_files/2017.04.20.13.43.45video.mp4"];
AVPlayer * player = [AVPlayer  playerWithURL:url];

AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];

playerViewController.player = player;
[playerViewController.view setFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.width)];

playerViewController.showsPlaybackControls = YES;

[self.view addSubview:playerViewController.view];

[player play];
