【iOS开发】解决“点击MPMoviePlayerController播放视频时，出现一个黑屏闪屏问题”

标签：ios   mpmovieplayercontrol   

当点击某按钮播放视频时，如果在按钮触发函数时alloc MPMoviePlayerController对象，同时加载资源文件，因为加载资源文件也需要时间，这时会有一个短暂的黑色闪屏，这点体验很不好，有一个好的解决方案是，提前alloc预加载好该MoviePlayer对象，点击按钮时直接调用play。

预加载相关代码：

//预加载视频，避免出现黑屏
    NSString *videoPath=[[NSBundle mainBundle]pathForResource:@"startVideo" ofType:@"mp4"];
    self.movieController=[[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:videoPath]];
    [[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(movieFinish:) name:MPMoviePlayerPlaybackDidFinishNotification object:self.movieController];
    self.movieController.scalingMode=MPMovieScalingModeAspectFill;
    [self.view insertSubview:movieController.view belowSubview:bgImgView];
    self.movieController.view.frame=CGRectMake(0,0, 1024, 768);
    [self.movieController setControlStyle:MPMovieControlStyleNone];      //去掉进度条
    self.movieController.initialPlaybackTime = -1.0;
    [self.movieController setShouldAutoplay:NO];
    [self.movieController prepareToPlay];

[self.movieController setShouldAutoplay:NO];

    [self.movieController prepareToPlay];
