You probably want to start your search in CoreTelephony. That being said, if a call comes in, iOS's call-handling events will take over your app. In other words, your app will be suspended when the call comes in, and move back to the foreground when the call is complete. You can use CoreTelephony to get access to the CTCallCenter, which contains an array of CTCalls (calls in progress). CTCall does not contain the phone number for the call, to my knowledge though. Furthermore, you can't stop iOS from backgrounding your app to handle the call.
您可能想在CoreTelephony 中开始搜索。话虽如此，如果有电话进来，iOS 的呼叫处理事件将接管您的应用程序。换句话说，您的应用程序将在呼叫进入时暂停，并在呼叫完成时移回前台。您可以使用 CoreTelephony 访问 CTCallCenter，其中包含一组 CTCall（正在进行的呼叫）。据我所知，CTCall 不包含通话的电话号码。此外，您无法阻止 iOS 后台处理您的应用程序来处理呼叫。
