[iOS] [Bug report] isCallActive return undefined

As docs in https://reactnative.dev/docs/native-modules-ios, ReactNative method always return void so to pass value to JS layer, we need to use callback, Promise or eventEmitter.

Current iOS implement. Return boolean value in this method doesn’t send to JS layer

+ (BOOL)isCallActive:(NSString *)uuidString
{
    CXCallObserver *callObserver = [[CXCallObserver alloc] init];
    NSUUID *uuid = [[NSUUID alloc] initWithUUIDString:uuidString];

    for(CXCall *call in callObserver.calls){
        NSLog(@"[RNCallKeep] isCallActive %@ %d ?", call.UUID, [call.UUID isEqual:uuid]);
        if([call.UUID isEqual:[[NSUUID alloc] initWithUUIDString:uuidString]] && !call.hasConnected){
            return true;
        }
    }
    return false;
}

Js index:

isCallActive = async(uuid) => await RNCallKeepModule.isCallActive(uuid);

I already tried with Promise method, it’s work but not for my case. I needed to call this method each second so I changed to event emitter to prevent “illegal callback invocation from native module” error.

PR is not available atm.

@devWaleed I’m finally back at this part of our app and am giving this a look now. I’ll have a pr coming soon.

the best is to find different library.
