Can not seek with MPMoviePlayerController

Question

I am going to seek timeline on MPMediaPlayerController.

I tried with the undocumented method setCurrentTime of MPMediaPlayerController as follows.

[player setCurrentTime:1.f];

Then the apple crashs with follows...

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MPMoviePlayerController setCurrentTime:]: unrecognized selector sent to instance 0x5619fe0'

Answer 1

You can seek MPMoviePlayerController using the currentPlaybackTime property, which is documented in the MPMediaPlayback Protocol Reference.

So your code would look like:

[player setCurrentPlaybackTime:1.0];
