按下播放后，UIWebView上的QuickTime播放器iOS 9会发出警告

我想在UIWebView（iOS 9.2.1）上播放m3u8链接，当页面加载时，按下时会出现quickTime播放器的播放图标（仅在iPhone设备上）播放器填满所有屏幕，日志会发出以下警告：

这种情况不会发生在任何只有iPhone的iPad设备上。

甚至在“skinnier”应用程序上尝试了同样的警告，我正在使用UIWebView的加载请求：

 dispatch_async(dispatch_get_main_queue(), ^{ NSString *rec = [_m3u8 string"]; NSURL *url = [NSURL URLWithString:rec]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; self.WebView.allowsInlineMediaPlayback = YES; [self.WebView loadRequest:request]; }); 

感谢任何帮助的人。

Answer 1

UIWebView仍然没有太大的成功，但是有一个名为“WKWebView”的对象是来实现：

 #import  

然后在viewDidLoad等初始化：

 WKWebView *w = [[WKWebView alloc]initWithFrame:self.view.bounds]; NSURL *url = [NSURL URLWithString:@"yourLink.m3u8"]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; [w loadRequest:request]; [self.view addSubview:w]; 

还有一件事添加到.plist文件中：

应用程序传输安全设置 – 字典。

允许任意负载= YES。

它比UIWebView快得多，我没有在日志中得到上面提到的警告。

干杯。
