iOS 10:如何使用CallKit/CXCallObserver获得通话事件? [英] iOS 10 : How can I get a call event using CallKit/CXCallObserver?

问题描述

我在iOS 10中使用CXCallObserver更改了CTCallCenter.

I changed the CTCallCenter with CXCallObserver in iOS 10.

这是我的代码:

#import <CallKit/CXCallObserver.h>
#import <CallKit/CXCall.h>

-(void)viewDidLoad {

    CXCallObserver *callObserver = [[CXCallObserver alloc] init];
    [callObserver setDelegate:self queue:nil];

    ... ...
}

- (void)callObserver:(CXCallObserver *)callObserver callChanged:(CXCall *)call {
    if (call.hasConnected) {
        NSLog(@"********** voice call connected **********/n");        
    } else if(call.hasEnded) {
        NSLog(@"********** voice call disconnected **********/n");        
    }
}

但是我无法收到语音通话事件，并且得到了这样的警告:

But I can't get a voice call event and I got a warning like this:

Sending 'HomeViewController *const __strong' to parameter of incompatible type 'id<CXCallObserverDelegate> _Nullable

请帮助我.

推荐答案

您错过了CXCallObserverDelegate.

You missed the CXCallObserverDelegate.

@interface HomeViewController : UIViewController <CXCallObserverDelegate>

@end

然后，警告将消失，并且您会收到语音呼叫事件.希望对您有帮助.

Then the warning will disappear and you get a voice call event. I hope this help you.
