IOS以编程方式拒绝来电？

Question

有什么方法可以快速以编程方式拒绝来电。我的代码是这样的：

self.callCenter.callEventHandler = {(_ call: CTCall) -> Void in
            if call.callState == CTCallStateDisconnected {
                print("Call has been disconnected")
            }
            else if call.callState == CTCallStateConnected {
                print("Call has just been connected")
            }
            else if call.callState == CTCallStateIncoming {
                print("Call is incoming")
                }
            else {
                print("None of the conditions")
            }

我以这种方式检测来电状态。但我不知道如何更改 callstate 的 CTCAll 。请帮帮我！。

    return self;
