iOS10

头文件:import CallKit.CXCallObserver声明全局属性<必须的,不然代理无法监听>let callObserver = CXCallObserver()//拨号let number = "10086"let callWebVIEw = UIWebVIEw()callWebVIEw.loadRequest(URLRequest(url:URL(string: "tel:\(number)")!))vIEw.addSubvIEw(callWebVIEw)UIApplication.shared.open(URL(string:number)!,options: ["":""],completionHandler: nil)设置代理callObserver.setDelegate(self,queue: dispatchQueue.main)实现代理方法:extension VIEwController: CXCallObserverDelegate {    func callObserver(_ callObserver: CXCallObserver,callChanged call: CXCall) {        if call.isOutgoing {            print("电话播出")            if call.hasConnected {                print("电话接通")                operation(state: CurrentState.HasConnected)            }            if call.hasEnded {                print("电话挂断")                operation(state: CurrentState.HasEnded)            }            if call.isOnHold {                print("无人接听挂断")                operation(state: CurrentState.IsOnHold)            }        } else {            print("other error")        }    }}
