To make it clearer, remoteControlReceivedWithEvent was never called when the control centre music control is pressed.

Sorry to get back to this old issue.
We tested blocking iOS7 control centre music remote-control by intercepting remote control events, but control centre seems to have bypassed ALL music control events including UIEventSubtypeRemoteControlPause and UIEventSubtypeRemoteControlPlay, and UIEventSubtypeRemoteControlTogglePlayPause.

The same blocking code still works perfectly with iOS6 devices.

Is it that control centre has its own protocol for remote control or that the way to intercept remote-control events has changed in iOS7? Here is what we do:

1. Added a method in our appDelegate:
- (BOOL)canBecomeFirstResponder {
return YES;

}

2. Call this in applicationDidBecomeActive:

[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

// Set itself as the first responder
[self becomeFirstResponder];

3. Call this in applicationWillResignActive

// Turn off remote control event delivery
[[UIApplication sharedApplication] endReceivingRemoteControlEvents];

// Resign as first responder
[self resignFirstResponder];

4. Finally added

- (void)remoteControlReceivedWithEvent:(UIEvent *)receivedEvent {

if (receivedEvent.type == UIEventTypeRemoteControl) {

switch (receivedEvent.subtype) {

case UIEventSubtypeRemoteControlTogglePlayPause:

NSLog(@"Received: UIEventSubtypeRemoteControlTogglePlayPause\n");
break;

case UIEventSubtypeRemoteControlPreviousTrack:
NSLog(@"Received: UIEventSubtypeRemoteControlPreviousTrack\n");
break;

case UIEventSubtypeRemoteControlNextTrack:
NSLog(@"Received: UIEventSubtypeRemoteControlNextTrack\n");

break;

case UIEventSubtypeRemoteControlPlay:
NSLog(@"Received: UIEventSubtypeRemoteControlPlay\n");

break;

case UIEventSubtypeRemoteControlPause:
NSLog(@"Received: UIEventSubtypeRemoteControlPause\n");

break;

case UIEventSubtypeRemoteControlStop:
NSLog(@"Received: UIEventSubtypeRemoteControlStop\n");

break;

default:
NSLog(@"Received: Some remove control events\n");

break;
}
}
}

Any pointer will be appreciated.

Ah, that would make sense.
Thanks for the tip!

That’s because in iOS7 there is no UIEventSubtypeRemoteControlTogglePlayPause anymore, but different events are sent for play and pause (UIEventSubtypeRemoteControlPause and UIEventSubtypeRemoteControlPlay, to be precise).

I fixed the problem you have in my apps simply by checking for the right event(s) in -remoteControlReceivedWithEvent:, no other changes were needed.

The method used to work on iOS6 with the ear-bud remote control and the springboard.
I can go back to try again. But our QA found that they didn't work for the Control Center on a device running iOS7.

I believe you’re looking for this on UIApplication:

Registering for Remote Control Events

– beginReceivingRemoteControlEvents

– endReceivingRemoteControlEvents

Thanks for the response Hunter.

I want to intercept the music player control messages from the Control Center.

Thanks,

I’m not sure there is any as Control Center is not customizable by developers.

What sort of questions did you have?
