大佬教程收集整理的这篇文章主要介绍了全屏播放YouTube视频,仅允许针对iOS7和iOS8的视频进行旋转，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我试图在UIWebView上播放YouTube视频,如下所示：

// Create the URL
_videoUrl = [NSURL URLWithString:[NSString StringWithFormat:@"https://www.youtube.com/watch?v=%@",_videoID]];

// Create the request with the URL
NSURLrequest *requestObj = [NSURLrequest requestWithURL:_videoUrl];

// Load the request into the Web View
[_webView loadrequest:requestObj];

youtube页面显示,当我对视频开始播放时,但它没有旋转.

我花了一周时间寻找不同的解决方案,通过实现“shouldAutorotate”和“supportedInterfaceOrientations”,但没有成功！

我尝试的最后一件事是在视频以全屏模式播放时添加一个监听器,在AppDelegate.m中我添加了“didFinishLaunchingWithOptions”代码如下：

[[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(moviePlayerWillEnterFullscreenNotification:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(moviePlayerWillExitFullscreenNotification:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];

并实施：

- (void) moviePlayerWillEnterFullscreenNotification:(Nsnotification*)notification {
self.allowRotation = YES; }

- (void) moviePlayerWillExitFullscreenNotification:(Nsnotification*)notification {
self.allowRotation = NO; }

-(NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window {
if (self.forceLandscapeRight) {
    return UIInterfaceOrientationMaskLandscapeRight;
}
if (self.allowRotation) {
    return UIInterfaceOrientationMaskPorTrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

return UIInterfaceOrientationMaskPorTrait; }

问题是既没有调用“moviePlayerWillEnterFullscreenNotification”或“moviePlayerWillExitFullscreenNotification”.

请帮忙！

解决方法

找到答案：

我不得不使用

[[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(youTubeStarted:) name:@"UIMoviePlayerControllerDidEnterFullscreenNotification" object:nil];
 [[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(youTubeFinished:) name:@"UIMoviePlayerControllerWillExitFullscreenNotification" object:nil];

代替

[[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(moviePlayerWillEnterFullscreenNotification:) name:MPMoviePlayerWillEnterFullscreenNotification object:nil];
[[NsnotificationCenter defaultCenter] addObserver:self SELEctor:@SELEctor(moviePlayerWillExitFullscreenNotification:) name:MPMoviePlayerWillExitFullscreenNotification object:nil];

并在我的ViewControler中实现方法

-(BOOL) shouldAutorotate {
 return NO; }

-(NSUInteger)supportedInterfaceOrientations{
 return UIInterfaceOrientationMaskPorTrait; }

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
 return UIInterfaceOrientationPorTrait; }
