我将在 MPMediaPlayerController 上寻找时间线。
我尝试使用 MPMediaPlayerController 的未记录方法 setCurrentTime 如下。
[player setCurrentTime:1.f];
然后苹果崩溃了以下......
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MPMoviePlayerController setCurrentTime:]: unrecognized selector sent to instance 0x5619fe0'
