Ios 大厦及；在Swift 3.0中使用XMPP取消阻止用户

我在Swift中使用XMPP为阻止和取消阻止用户查看了很多博客和网站。 但是，没有一个例子对我有效。 任何人有代码片段，请与我分享。 多谢各位

func blockUser(userJID: String) {
   let privacyList = XMPPPrivacy(dispatchQueue: DispatchQueue.main)
    privacyList?.activate(xmppStream)
    privacyList?.addDelegate(self, delegateQueue: DispatchQueue.main)

     let privacyElement = XMPPPrivacy.privacyItem(withType: "jid", value: userJID, action: "deny", order: 0)
    XMPPPrivacy.blockIQs(privacyElement)
    XMPPPrivacy.blockMessages(privacyElement)
    XMPPPrivacy.blockPresence(in: privacyElement)
}

您需要使用用于阻塞功能

代码（Swift 3.0）：

添加阻止用户和取消阻止用户

//Blocking Managment
    self.xmppBlocking = XMPPBlocking()
    self.xmppBlocking!.autoRetrieveBlockingListItems = true
    self.xmppBlocking!.autoClearBlockingListInfo = true;
    self.xmppBlocking!.addDelegate(self, delegateQueue: DispatchQueue.main)
    self.xmppBlocking!.activate(self.xmppStream)
    self.xmppBlocking?.retrieveBlockingListItems()

    xmppBlocking?.blockJID(user.jid) 
    xmppBlocking?.unblockJID(user.jid)



extension BlockListVC : XMPPBlockingDelegate{

        public func xmppBlocking(_ sender: XMPPBlocking!, didBlockJID xmppJID: XMPPJID!){
           //Successfully blocked
        }

        public func xmppBlocking(_ sender: XMPPBlocking!, didNotBlockJID xmppJID: XMPPJID!, error: Any!){
            if(error is NSError){
                //print error message
            }
        }

        public func xmppBlocking(_ sender: XMPPBlocking!, didReceivedBlockingList blockingList: [Any]!) {
            //Received blocked list in this delegate method
        }

   public func xmppBlocking(_ sender: XMPPBlocking!, didUnblockJID xmppJID: XMPPJID!) {

    }

    public func xmppBlocking(_ sender: XMPPBlocking!, didNotUnblockJID xmppJID: XMPPJID!, error: Any!) {
        if(error is NSError){

        }
    }
  }

这完全取决于您的实现。所以，只要把你尝试过的东西贴出来就行了。此外，询问代码将使您的问题被否决，因为它是皱眉了。我已经张贴了一个问题的代码。现在你可以检查一下，让我知道我哪里出错了。

//Blocking Managment
    self.xmppBlocking = XMPPBlocking()
    self.xmppBlocking!.autoRetrieveBlockingListItems = true
    self.xmppBlocking!.autoClearBlockingListInfo = true;
    self.xmppBlocking!.addDelegate(self, delegateQueue: DispatchQueue.main)
    self.xmppBlocking!.activate(self.xmppStream)
    self.xmppBlocking?.retrieveBlockingListItems()

    xmppBlocking?.blockJID(user.jid) 
    xmppBlocking?.unblockJID(user.jid)



extension BlockListVC : XMPPBlockingDelegate{

        public func xmppBlocking(_ sender: XMPPBlocking!, didBlockJID xmppJID: XMPPJID!){
           //Successfully blocked
        }

        public func xmppBlocking(_ sender: XMPPBlocking!, didNotBlockJID xmppJID: XMPPJID!, error: Any!){
            if(error is NSError){
                //print error message
            }
        }

        public func xmppBlocking(_ sender: XMPPBlocking!, didReceivedBlockingList blockingList: [Any]!) {
            //Received blocked list in this delegate method
        }

   public func xmppBlocking(_ sender: XMPPBlocking!, didUnblockJID xmppJID: XMPPJID!) {

    }

    public func xmppBlocking(_ sender: XMPPBlocking!, didNotUnblockJID xmppJID: XMPPJID!, error: Any!) {
        if(error is NSError){

        }
    }
  }
