IOS: check if the phone is locked

Is there a way to check if the phone is locked? Or am I getting a notification that the phone is locked?

My application runs in the background, continues to play audio, so applicationWillResignActive: in fact, this is not what I'm looking for.

You cannot, right. Indirectly, you can view accelerometer enable / disable notifications .

Why do you want to detect this event in the first place?

Checkout UIApplicationProtectedDataWillBecomeUnavailable. This appears to be called when the device is locked. IOS4 + only.
