在iOS中完成视频更改方向

Question

我认为编码完成按钮无法正常工作，因为当视频开始播放和视频播放完成时，我正在更改屏幕方向，因此我需要回到正常编辑状态。

vid = [[MPMoviePlayerViewController alloc] initWithContentURL:url]; 
//[self presentModalViewController:vid animated:YES]; 
[self presentMoviePlayerViewControllerAnimated:vid]; 

NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeLeft]; 
[[UIDevice currentDevice] setValue:value forKey:@"orientation"]; 
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(donebutton) name:MPMoviePlayerDidExitFullscreenNotification object:vid]; 

，然后编码完成按钮方法

-(void) donebutton{ 
    NSLog(@"done"); 
    NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationPortrait]; 
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"]; 
}

希望这个代码将会帮助你改变设备的方向时，完成了视频播放。

-(void)playVideo { 
     moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; 

      [[NSNotificationCenter defaultCenter] 
      addObserver:self 
      selector:@selector(moviePlayBackDidFinish:) 
      name:MPMoviePlayerPlaybackDidFinishNotification 
      object:moviePlayer]; 

    [moviePlayer setFullscreen:YES animated:YES]; 
} 


- (void)moviePlayBackDidFinish:(NSNotification *)notification { 

moviePlayer = [notification object]; 
[[NSNotificationCenter defaultCenter] 
removeObserver:self 
name:MPMoviePlayerPlaybackDidFinishNotification 
object:moviePlayer]; 
// If the moviePlayer.view was added to full screen, it needs to be removed 

moviePlayer.fullscreen = NO; 

}
