IOS 10 Callkit does not display incoming call user interface

Question

I just implemented CallKit in our VOIP application, but I'm afraid to get an incoming call interface.

In my experiment, I just created a simple method that should display the interface of an incoming call, see below:

CXProviderConfiguration * configuration = [[CXProviderConfiguration alloc] initWithLocalizedName:@"Bitcall"]; CXProvider *callkitProvider = [[CXProvider alloc] initWithConfiguration: configuration]; [callkitProvider setDelegate:self queue:nil]; CXCallUpdate *update = [[CXCallUpdate alloc] init]; update.localizedCallerName = @"Ravadam Patel"; [callkitProvider reportNewIncomingCallWithUUID:[NSUUID UUID] update:update completion:^(NSError * _Nullable error) { if (error) { NSLog(@"Error: %@", error); } }]; 

Everything seems to be working fine, and I really get a printout of a call received with this code:

 - (void)handleCall { self.callCenter.callEventHandler = ^(CTCall *call){ if ([call.callState isEqualToString: CTCallStateConnected]) { //NSLog(@"call stopped"); } else if ([call.callState isEqualToString: CTCallStateDialing]) { } else if ([call.callState isEqualToString: CTCallStateDisconnected]) { NSLog(@"Call ended"); } else if ([call.callState isEqualToString: CTCallStateIncoming]) { NSLog(@"Call received"); } }; } 

But the user interface of the incoming call is not displayed. Is there something I'm missing?

thanks

CallKit does not work in iOS Simulator, so your application will need to run on the device.

In addition, I recommend comparing your application with the Speakerbox sample code published by Apple to see if any fragments from your implementation are missing.
