推荐答案

您必须使用 CoreTelephony Framework
您可以使用CTCall类获取有关调用状态的信息。 CTCallCenter允许您注册呼叫事件状态更改，但您的应用程序需要处于运行状态。当您的应用程序移动到后台时，您可能需要请求最长的后台时间（我猜是10分钟）。这些api仅适用于iOS 4.0及更高版本。你可以根据需要使用它们。

You will have to use CoreTelephony Framework You can get information about the state of the call by using the CTCall class. the CTCallCenter allows you to register for call event state changes but your app needs to be in running state.You may want to request the maximum backgrounding time ( 10 minutes I guess) when your application is moved to the background. These api's are only available in iOS 4.0 and later. you can use these as required.

extern NSString const *CTCallStateDialing;
extern NSString const *CTCallStateIncoming;
extern NSString const *CTCallStateConnected;
extern NSString const *CTCallStateDisconnected;
