Can I hide the rewind button in the iOS Lock Screen Music controls?

My app doesn’t support going back to previous tracks, and I’m wondering if I can tell the lock screen music controls to hide their rewind/previous track button. I use the MPNowPlayingInfoCenter to communicate that information to the lock screen.

Pretty simple question, can it be done? For instance, to only show Play/Pause, and Skip Forward?

Solution

  • As of iOS 7.1 there is a way to customize the controls available in the lock screen and command center (and probably many other accessories): MPRemoteCommandCenter.

    Regarding your question you can do the following:

    [MPRemoteCommandCenter sharedCommandCenter].previousTrackCommand.enabled = NO;
[MPRemoteCommandCenter sharedCommandCenter].skipBackwardCommand.enabled = NO;
[MPRemoteCommandCenter sharedCommandCenter].seekBackwardCommand.enabled = NO;

// You must also register for any other command in order to take control
// of the command center, or else disabling other commands does not work.
// For example:
[MPRemoteCommandCenter sharedCommandCenter].playCommand.enabled = YES;
[[MPRemoteCommandCenter sharedCommandCenter].playCommand addTarget:self action:@selector(play)];
