I want to detect when the volume button is pressed. I've try a lot of thing like add an Observer like
AVAudioSession.sharedInstance().addObserver(self, forKeyPath: #keyPath(AVAudioSession.outputVolume), options: [.old, .new], context: nil)
then Override :
override internal func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey: Any]?, context: UnsafeMutableRawPointer?)
But I want to trigger this function even if the sound is at max.
There is a way to do that without changing so sound to lower it ?
Try
AVAudioSession.sharedInstance().setActive(true)
AVAudioSession.sharedInstance().observe(\.outputVolume) { [weak self] (audioSession, _) in
<#code#>
}
