ios webView中的视频播放支持横屏旋转

1.添加系统通知

//即将进入全屏

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willEnterFullscreenScreen:) name: MPMoviePlayerWillEnterFullscreenNotification object:nil];

//即将推出全屏

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullscreenScreen:) name: MPMoviePlayerWillExitFullscreenNotification object:nil];

2.实现方法

//将要进入全屏

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

NSLog(@"将要进入全屏状态");

if (self.contentView.bounds.size.width < self.contentView.bounds.size.height) {

[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationLandscapeRight] forKey:@"orientation"];

} else {

[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:@"orientation"];

}

}

//将要推出全屏

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

if (self.contentView.bounds.size.width < self.contentView.bounds.size.height) {

[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationLandscapeRight] forKey:@"orientation"];

} else {

[[UIDevice currentDevice] setValue:[NSNumber numberWithInteger:UIInterfaceOrientationPortrait] forKey:@"orientation"];

}

}
