Question or problem in the Swift programming language:
I am using CTCallCenter in my project. Now it’s deprecated, I would like to know what are alternatives? How to get the event for the voice call?
How to solve the problem:
This is poorly documented, but I’ve found this mention in CTCallCenter public header files:
“Replaced by ”
So, from iOS 10 you should use CXCallObserver class of new CallKit framework to retrieve info about active calls:
CXCallObserver *callObserver = [[CXCallObserver alloc] init];
Provide object, conforming to CXCallObserverDelegate protocol and queue, on which you want to perform delegate callbacks:
// If queue is nil, then callbacks will be performed on main queue [callObserver setDelegate:self queue:nil]; // Don't forget to store reference to callObserver, to prevent it from being released self.callObserver = callObserver;
and implement the following method on your delegate object:
- (void)callObserver:(CXCallObserver *)callObserver callChanged:(CXCall *)call { if (call.hasConnected) { // perform necessary actions } }
