# [iOS监听电话来电、挂断、拨号等][iOS] #

以下，来讲解在app内如何调用打电话功能和监听电话来电、挂断、拨号等功能。

简单的UI布局：

首先，先实现拨打电话的功能，以便于后续测试：

// 拨打电话
    - (IBAction)dialingButtonClick:(UIButton *)sender {
        NSURL *url = [NSURL URLWithString:@"tel:138xxxxxxxx"];// 填入有效电话号码
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        UIWebView * callWebview = [[UIWebView alloc] init];
        [callWebview loadRequest:request];
        [self.view addSubview:callWebview];
    }

然后，监听电话，首先需要我们导入一个框架并引入头文件：

// 导入框架 CoreTelephony.framework
    #import <CoreTelephony/CTCallCenter.h>
    #import <CoreTelephony/CTCall.h>

监测电话：

// 监测电话
    - (void)monitorCall {
        self.callCenter.callEventHandler = ^(CTCall* call) {
            if (call.callState == CTCallStateDisconnected) {
                NSLog(@"电话结束或挂断电话");
            } else if (call.callState == CTCallStateConnected){
                NSLog(@"电话接通");
            } else if(call.callState == CTCallStateIncoming) {
                NSLog(@"来电话");
            } else if (call.callState ==CTCallStateDialing) {
                NSLog(@"拨号打电话(在应用内调用打电话功能)");
            }
        };
    }
    
    #pragma mark - getter Methods
    
    - (CTCallCenter *)callCenter {
        if (!_callCenter) {
            _callCenter = [[CTCallCenter alloc] init];
        }
        return _callCenter;
    }

// 注：值得说明的是，CTCallCenter 呼叫中心必须强引用，防止对象被释放掉而无法监测电话。

场景：

1、点击按钮，拨号时：

    2016-06-08 16:38:15.520 Demo_监听电话状态[5732:1781472] applicationDidBecomeActive
    2016-06-08 16:38:15.621 Demo_监听电话状态[5732:1784552] 拨号打电话(在应用内调用打电话功能)

2、手机来电，然后挂断：

    2016-06-08 16:40:11.819 Demo_监听电话状态[5732:1781472] applicationWillResignActive
    2016-06-08 16:40:13.746 Demo_监听电话状态[5732:1785743] 电话结束或挂断电话
    2016-06-08 16:40:15.267 Demo_监听电话状态[5732:1781472] applicationDidBecomeActive

3.手机来电，接通，然后挂断：

2016-06-08 16:42:11.479 Demo_监听电话状态[5732:1785743] 来电话
    2016-06-08 16:42:11.819 Demo_监听电话状态[5732:1781472] applicationWillResignActive
    2016-06-08 16:42:11.919 Demo_监听电话状态[5732:1785743] 电话接通
    2016-06-08 16:42:13.746 Demo_监听电话状态[5732:1785743] 电话结束或挂断电话
    2016-06-08 16:42:15.267 Demo_监听电话状态[5732:1781472] applicationDidBecomeActive
