I thought that I could check the status of an AVPlayer simply by the property "rate".
This is how I create a player instance:
player = AVPlayer(URL: stream) // streaming from the internet
player!.play()
At some later point I would do something like this
println(player!.rate)
This is what I discovered:
Do you have any idea why that happens and how I could check the stream condition otherwise?
I have tried an observer so far:
player!.addObserver(self, forKeyPath: "status", options: NSKeyValueObservingOptions.New, context: nil)
But even the method "observeValueForKeyPath" does not get fired in my iPhone test case.
Check out the Apple docs here and scroll to the "Key-Value Observing" section. Especially #3 in that section.
It helped me get my implementation to work. My resulting code looks like this:
//Global
var player = AVPlayer()
func setUpPlayer() {
//...
// Setting up your player code goes here
self.player.addObserver(self, forKeyPath: "status", options: NSKeyValueObservingOptions(), context: nil)
//...
}
// catch changes to status
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
print("obsrved")
}
