iOS:无法在CallKit中获得传出呼叫事件 [英] iOS: Could not get outgoing call events in CallKit

问题描述

我正在使用"telprompt"通过我的应用进行呼叫，但是当呼叫结束时，我希望显示一个新的视图控制器并点击一个API来获取数据，所以我想接收一个事件以打开一个弹出窗口然后点击API.

I'm making a call through my app using 'telprompt', but when call ends I want a new view controller to be shown and hit an API to get data, So I want to receive an event to open a pop up and hit API.

我尝试使用CallKit，但是未调用Delegate方法.

I have tried using CallKit, but Delegate method is not getting called.

这是我的代码.

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

我符合CXCallObserverDelegate

I have conform to CXCallObserverDelegate

在viewDidLoad中:

In viewDidLoad:

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

代理方法:

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

    } else if(call.hasEnded) {

        NSLog(@"********** voice call disconnected **********/n");

    }
}

上面的方法没有被调用，您可以看到我已经设置了委托，我不知道我在做什么错.

Above method is not getting called, As you can see I have already set delegate, I don't know what I am doing wrong.

推荐答案

在为控制器创建了强大的引用/属性后，我丢失了对callObserver对象的强大引用.

I was missing a strong reference to the callObserver object after creating a strong reference/property to my controller it works well.

添加属性，并将callObserver对象放入其中.

Add the property and put callObserver object in it.

@property (nonatomic, strong) CXCallObserver *callObserver;

viewDidLoad:

viewDidLoad:

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

现在将调用Delegate方法.

Now Delegate method will be called.

干杯!!!
