Apple doc says "you can disable the corresponding MPRemoteCommand object by setting its enabled property to NO."

I referred Is there a public way to force MPNowPlayingInfoCenter to show podcast controls? and I was able to disable/enable a particular command on lock screen control.

However I want to disable all the controls from lock screen control since I am playing a radio and it do not support either of the action - "Play/Pause/Next/Previous"

I tried following code snippet:

MPRemoteCommandCenter *remoteCommandCenter = [MPRemoteCommandCenter sharedCommandCenter];
remoteCommandCenter.previousTrackCommand.enabled = NO;
[remoteCommandCenter.previousTrackCommand removeTarget:self];
remoteCommandCenter.nextTrackCommand.enabled = NO;
[remoteCommandCenter.nextTrackCommand removeTarget:self];
            
remoteCommandCenter.skipBackwardCommand.enabled = NO;
[remoteCommandCenter.skipBackwardCommand removeTarget:self];
remoteCommandCenter.skipForwardCommand.enabled = NO;
[remoteCommandCenter.skipForwardCommand removeTarget:self];
            
remoteCommandCenter.bookmarkCommand.enabled = NO;
[remoteCommandCenter.bookmarkCommand removeTarget:self];

remoteCommandCenter.playCommand.enabled = NO;
[remoteCommandCenter.playCommand removeTarget:self];
            
remoteCommandCenter.pauseCommand.enabled = NO;
[remoteCommandCenter.pauseCommand removeTarget:self];

However it didn't work. Disabling everything enables pause, previous, next button on lock screen. Any help would be greatly appreciated.

Yes "you can disable the corresponding MPRemoteCommand object by setting its enabled property to NO."

But If you are disabling all the buttons then don't remove the target or add a target which will probably do nothing. There is no document explaining why we have to do this but it works this way.

Try the following code this will work.

MPRemoteCommandCenter *remoteCommandCenter = [MPRemoteCommandCenter sharedCommandCenter];
remoteCommandCenter.previousTrackCommand.enabled = NO;
remoteCommandCenter.nextTrackCommand.enabled = NO;
remoteCommandCenter.skipBackwardCommand.enabled = NO;
remoteCommandCenter.skipForwardCommand.enabled = NO;
remoteCommandCenter.bookmarkCommand.enabled = NO;
remoteCommandCenter.playCommand.enabled = NO;
remoteCommandCenter.pauseCommand.enabled = NO;


[remoteCommandCenter.previousTrackCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.nextTrackCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.skipBackwardCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.skipForwardCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.bookmarkCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.playCommand addTarget:self action:@selector(actionDoNothing:)];
[remoteCommandCenter.pauseCommand addTarget:self action:@selector(actionDoNothing:)];

  • Thanks Sagar. Its working. Though not sure how target is related to it. I had added feedback at Apple for the same. – Anoop Nyati Aug 24 '16 at 10:52
