我正在使用iOS中的MPMediaplayer框架制作视频播放器,我需要在我的应用程序中播放两个视频。(即当用户拥有强大的网络信号时,我的第一个视频将播放)。 我的第二个视频播放器将在他们的低网络播放。我需要在wifi或3G等播放我的视频...我的第一件事是如何在我的iphone手机和3G速度中检测我的wifi速度。我需要在MBPS中获得移动wifi速度。我正在尝试编写一些代码。但这对我不起作用。提前谢谢。

您可以播放高分辨率视频用于wifi和低分辨率视频的移动数据。
Reachability *reachability = [Reachability reachabilityForInternetConnection];
[reachability startNotifier];
NetworkStatus status = [reachability currentReachabilityStatus];
if(status == NotReachable)
{
//No internet
}
else if (status == ReachableViaWiFi)
{
//WiFi Play high resolution video
}
else if (status == ReachableViaWWAN)
{
//3G Play low resolution video
}
如果您要通过3g网络传输高分辨率视频,Apple可以拒绝您的应用。
