ios – 退出全屏后MPMoviePlayerController缩放模式问题

概述我只是通过使用MPMoviePlayerController播放视频…我的代码是 -(void)playMovie:(NSURL *)url{ moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; if (IDIOM==IPAD) { [moviePlaye 我只是通过使用MPMovIEPlayerController播放视频…我的代码是

-(voID)playMovIE:(NSURL *)url{    movIEPlayer =    [[MPMovIEPlayerController alloc]     initWithContentURL:url];    if (IdioM==IPAD) {        [movIEPlayer.vIEw setFrame:CGRectMake(22,100,720,300)];    }    else    {        (IS_IPHONE_5)? [movIEPlayer.vIEw setFrame:CGRectMake(22,70,280,150)]:[movIEPlayer.vIEw setFrame:CGRectMake(22,40,260,140)];    }    [_scrollVIEw addSubvIEw:movIEPlayer.vIEw];    movIEPlayer.scalingMode =MPMovIEScalingModeFill;    [movIEPlayer preparetoPlay];    [movIEPlayer play];    [[NSNotificationCenter defaultCenter] addobserver:self selector:@selector(movIEPlayerDIDEnterFullscreen:) name:MPMovIEPlayerDIDEnterFullscreenNotification object:Nil];    [[NSNotificationCenter defaultCenter] addobserver:self selector:@selector(movIEPlayerDIDExitFullScreen:) name:MPMovIEPlayerDIDExitFullscreenNotification object:Nil];}-(voID)movIEPlayerDIDEnterFullscreen :(ID)sender{    NSLog(@"fullscreen");   [movIEPlayer play];    movIEPlayer.scalingMode =MPMovIEScalingModeFill;}- (voID) movIEPlayerDIDExitFullScreen:(ID)sender {    NSLog(@"exit full screen");    [movIEPlayer play];    movIEPlayer.scalingMode =MPMovIEScalingModeFill;}

这里当我最初播放视频时将处于“MPMovIEScalingModeFill”模式…但我的问题是如果我按全屏它会在全屏显示视频..当我按退出“全屏”然后我的视频模式转到“MPMovIEScalingModeAspectFit “mode.but我需要始终处于”MPMovIEScalingModeFill“模式.我的代码出错了.请帮帮我……

解决方法 我相信这会生成MPMovIEPlayerScalingModeDIDChangeNotification.

[[NSNotificationCenter defaultCenter] addobserver:self                 selector:@selector(movIEScalingModeDIDChange:)                 name:MPMovIEPlayerScalingModeDIDChangeNotification                 object:nil];

MPMovIEPlayerScalingModeDIDChangeNotification

在电影播放器​​的缩放模式发生变化时发布.没有userInfo字典.缩放模式可以通过编程或用户交互进行更改.要设置或检索影片播放器的缩放模式,请访问其scalingMode属性.状态已更改的电影播放器​​可用作与通知关联的对象.
