I have look around and all I can find is checking the callState of CTCallCenter. However, this works by listening to an event – which depending on whether the application is active/suspended/resumed the event can be raised at different time.
What I need is rather than listening to event and got told when call is connected, I want to decide myself when to ask if the call is connected.
Use case: When phone call is connected – user knows and will always click on the app icon, which will open the app. At this time I just want to run a quick function to check if currently on call or not.
Is this even possible?
The
CTCallCenterobject has acurrentCallsproperty which is anNSSetof the current calls. If there is a call then thecurrentCallsproperty should be != nil.If you want to know if any of the calls is actually connected, then you’ll have to iterate through the current calls and check the
callStateto determine if it isCTCallStateConnectedor not.
