推荐答案

要将核心电话通知添加到程序中，请包含以下代码并编译到Core Telephony框架的链接.这段代码会将您的程序添加为注册的观察者.

To add core telephony notification to your program, include the following code and compile linking to the Core Telephony framework. This code adds your program as a registered observer.

id ct = CTTelephonyCenterGetDefault();
CTTelephonyCenterAddObserver(ct, NULL, callback, NULL, NULL, CFNotificationSuspensionBehaviorHold);

要监视传入的通知，您需要构建作为添加给添加观察者调用的参数提供的回调例程:

To monitor the incoming notifications, you need to build the callback routine you supplied as an argument to the add observer call:

static void callback(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo)
 { ... }
