在iOS 10中获取电话状态

Question

我希望在我的应用中获得电话状态.
经过一番搜索,我找到了CoreTelephony框架.但是在iOS 10中已经弃用了.那么还有其他可用选择吗？
我也找到了CallKit.iOS 10中的一个新框架.但是没有得到与我搜索时相同的呼叫状态.

import CallKit进入你的AppDelegate并添加以下代码:

// AppDelegate
var callObserver: CXCallObserver! // add property

// in applicationDidFinishLaunching...
callObserver = CXCallObserver()
callObserver.setDelegate(self, queue: nil) // nil queue means main thread

extension AppDelegate: CXCallObserverDelegate {
    func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {
        if call.hasEnded == true {
            print("Disconnected")
        }
        if call.isOutgoing == true && call.hasConnected == false {
            print("Dialing")
        }
        if call.isOutgoing == false && call.hasConnected == false && call.hasEnded == false {
            print("Incoming")
        }

        if call.hasConnected == true && call.hasEnded == false {
            print("Connected")
        }
    }
}

你可以试试这段代码:

1. 创建调用观察者的实例

   @property ( nonatomic ) CXCallObserver *callObserver;
   

2. 启动实例并设置委托

   _callObserver = [CXCallObserver new];
           [_callObserver setDelegate:self queue:dispatch_get_main_queue()];
   

3. 添加调用观察者委托

   - (void)callObserver:(CXCallObserver *)callObserver callChanged:(CXCall *)call{
   
       if (call == nil || call.hasEnded == YES) {
           NSLog(@"CXCallState : Disconnected");
       }
   
       if (call.isOutgoing == YES && call.hasConnected == NO) {
           NSLog(@"CXCallState : Dialing");
       }
   
       if (call.isOutgoing == NO  && call.hasConnected == NO && call.hasEnded == NO && call != nil) {
           NSLog(@"CXCallState : Incoming");
       }
   
       if (call.hasConnected == YES && call.hasEnded == NO) {
           NSLog(@"CXCallState : Connected");     
       }
   }
   

在Swift 4.2中:

var callObserver: CXCallObserver()

callObserver.setDelegate(self, queue: DispatchQueue.main)

func callObserver(_ callObserver: CXCallObserver, callChanged call: CXCall) {

    if call == nil || call.hasEnded == true {
        print("CXCallState : Disconnected")
    }

    if call.isOutgoing == true && call.hasConnected == false {
        print("CXCallState : Dialing")
    }

    if call.isOutgoing == false && call.hasConnected == false && call.hasEnded == false && call != nil {
        print("CXCallState : Incoming")
    }

    if call.hasConnected == true && call.hasEnded == false {
        print("CXCallState : Connected")
    }
}

Apple 不允许您访问这些信息，尽管您可以通过使用第三方库来访问这些信息，但您的应用程序在提交到 App Store 时将被拒绝，因为 Apple 不允许访问敏感的用户信息。
