推荐答案

您可以在
subscriberCellularProviderDidUpdateNotifier 注册通知.apple.com / library / ios / #documentation/ NetworkingInternet / Reference / CTTelephonyNetworkInfo / Reference / Reference.htmlrel =nofollow> CTTelephonyNetworkInfo

You are able to sign up for a notification using subscriberCellularProviderDidUpdateNotifier in CTTelephonyNetworkInfo

但是，只有在应用程序运行时发生交换时，才会通知您。当您的应用未运行时，您仍然无法检测用户是否将SIM卡从同一位运营商更改为另一张SIM卡。

However you will only be notified if the swap occurs while your app is running. You will still be unable to detect if the user changes the SIM to another SIM from the same operator when your app is not running.
