从 Objective-C 转换为 Swift 的代码中的重新声明无效

Question

我正在尝试将代码从 Objective-C 转换为 Swift -

Objc-C 部分 - 没有错误。

AppDelegate:

- (OWTConferenceClient*)conferenceClient{
return _conferenceClient;
}

-(void)conferenceClient:(OWTConferenceClient *)client didReceiveMessage:(NSString *)message from:(NSString *)senderId{
  }

- (void)conferenceClient:(OWTConferenceClient *)client didAddParticipant:(OWTConferenceParticipant *)user{
}

-(void)conferenceClient:(OWTConferenceClient *)client didAddStream:(OWTRemoteStream *)stream{
}

到Swift

AppDelegate:

func conferenceClient() -> OWTConferenceClient {  <--- Error here: Invalid redeclaration of 'conferenceClient()'

return conferenceClient
}

 func conferenceClient(_ client:OWTConferenceClient, didAdd stream:OWTRemoteStream){
}

func conferenceClient(_ client:OWTConferenceClient, didAdd user:OWTConferenceParticipant) {
}

func conferenceClient(_ client:OWTConferenceClient, didReceiveMessage message:String, from senderId:String) {
}

Swift 部分有什么问题？

Answer 1

可能是您有一个名为 conferenceClient 的（全局或实例）变量，它会干扰该函数。

您需要重命名变量（在 ObjC 中，它有一个下划线 _conferenceClient）
