How to assign AVPlayer play/pause button iOS? - iphone

Question

I have asked this question before few days but nobody answer me and I could not find the solution.
So I want to ask the same question again and please answer me if you know the answer.
I want to assign these buttons in the picture to my avplayer play/pause button.
Note: My application icons appear in the now playing bar instead of Music icon, my application works fine in background .
Any help please.

Answer 1

To allow delivery of remote-control events, you must call the beginReceivingRemoteControlEvents method of UIApplication.
You then respond to the remote control events by implementing the remoteControlReceivedWithEvent: method like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
...
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[[UIApplication sharedApplication] becomeFirstResponder];
return YES;
}
- (void)remoteControlReceivedWithEvent:(UIEvent *)event
{
switch (event.subtype)
{
case UIEventSubtypeRemoteControlPlay:
// play code
...
break;
case UIEventSubtypeRemoteControlTogglePlayPause:
// toggle code
...
break;
case UIEventSubtypeRemoteControlNextTrack:
// next code
...
break;
default:
break;
}
}

Note:
"In iOS 7.1 and later, use the shared MPRemoteCommandCenter object to register for remote control events. You do not need to call this method (note: beginReceivingRemoteControlEvents) when using the shared command center object."
