如何獲取失敗/掉線的信息？我們有私人API嗎？

Answer 1

考慮檢查iOS的呼叫中心API：http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Reference/CTCallCenter/Reference/Reference.html

例子：

self.callCenter = [[CTCallCenter alloc] init]; 

self.callCenter.callEventHandler = ^(CTCall* call) { 


    if ([call.callState isEqualToString:CTCallStateIncoming]) { 


    } else if ([call.callState isEqualToString:CTCallStateDialing]) { 


    } else if ([call.callState isEqualToString:CTCallStateConnected]) { 


    } else if ([call.callState isEqualToString:CTCallStateDisconnected]) { 


    }
