I have an requirement that to handle headphone play/pause button events in foreground. How ever I am able to handle the same scenario in background using the below code
You must check this criteria:
Implement this function:
- (void)remoteControlReceivedWithEvent:(UIEvent *)theEvent
{
if (theEvent.type == UIEventTypeRemoteControl)
{
switch(theEvent.subtype) {
case UIEventSubtypeRemoteControlTogglePlayPause:
//Insert code
break;
case UIEventSubtypeRemoteControlPlay:
//Insert code
break;
case UIEventSubtypeRemoteControlPause:
// Insert code
break;
case UIEventSubtypeRemoteControlStop:
//Insert code.
break;
default:
return;
}
}
}
...obviously, replace the "//insert code" with whatever functionality is relevent in your app.
3>Finally, in order for that above function to be called, insert this in your viewDidAppear event:
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
if ([self canBecomeFirstResponder]) {
[self becomeFirstResponder];
}
