iOS实战【小微信】之私聊功能实现

这里我们用融云来实现私聊功能，首先创建小微信的应用，其次在IM服务中选择API调试；补充userId和name：

选择提交得到如下结果：

并初始化appkey与测试连接：

        //初始化appkey
        RCIM.sharedRCIM().initWithAppKey("8luwapkvu3y4l")     
        //用token测试链接
        RCIM.sharedRCIM().connectWithToken("KVQA8zlsxifN+8wBYfrdzFGHWMnd1yenzzdqyv6OVpxClvCAxJwi2ZHpNzOeray8pGD1uBAhM8sXBEFU+k/VLQ==", success: {
            (_)-> Void in
             print("连接成功！")
            })        
            }, error: { (_) -> Void in
                print("连接失败！")
        }){
            ()->Void in
            print("Token不正确，或已经失效！")
        }
    }

然后我们需要设置当前信息：

            let currentUserInfo = RCUserInfo(userId: "xiong1", name:"熊1", portrait:"http://user.qzone.qq.com/1159565251/4")
            RCIMClient.sharedRCIMClient().currentUserInfo = currentUserInfo

添加私聊功能；新建一个RCConversationViewController,并添加如下代码：

self.setMessageAvatarStyle(._USER_AVATAR_CYCLE)
self.targetId = "xiong2"
self.userName = "熊2"

self.conversationType = .ConversationType_PRIVATE

self.title = "与" + self.userName + "对话中"

在链接服务器的时候，由于UI界面和后台需要分开；故需要在该段代码调用闭包返回的时候，让其回到主线程：

    func connectserver(completion:()->Void){
        //初始化appkey
        RCIM.sharedRCIM().initWithAppKey("8luwapkvu3y4l")
        //用token测试链接
        RCIM.sharedRCIM().connectWithToken("WxdIW9mMaXG065raJ0F6T2HUWf58pJ6ADt3rlcK4W2GMHZgdePTYxizmS8RsC0e4NO6WR9TdempORT15+jUD9g==", success: {
            (_)-> Void in
             print("连接成功！")
            let currentUserInfo = RCUserInfo(userId: "xiong1", name:"熊1", portrait:"http://user.qzone.qq.com/1159565251/4")
            RCIMClient.sharedRCIMClient().currentUserInfo = currentUserInfo    
            dispatch_async(dispatch_get_main_queue(), {
                () -> Void in
                completion()
            })           
            }, error: { (_) -> Void in
                print("连接失败！")
        }){
            ()->Void in
            print("Token不正确，或已经失效！")
        }
    }

也可以添加多个用户信息：

   func getUserInfoWithUserId(userId: String!, completion: ((RCUserInfo!) -> Void)!) {    
        let userInfo = RCUserInfo()
        userInfo.userId = userId    
        switch userId {
            case "xiong":
            userInfo.name = "熊"
            userInfo.portraitUri = "http://photo.renren.com/photo/287307670/album-321349882/v7#photo/287307670/8023349882"    
            case "xiong1":
            userInfo.name = "熊1"
            userInfo.portraitUri = "http://photo.renren.com/photo/287307670/album-321349882/v7#photo/287307670/7991476622"
              default:
            print("无此用户")
        }  
        return completion(userInfo)
    }

并在ConversationListViewController中添加下述代码：

       appDelegate?.connectserver({
          () -> Void in
           self.setDisplayConversationTypes([
            RCConversationType.ConversationType_APPSERVICE.rawValue,
            RCConversationType.ConversationType_CHATROOM.rawValue,
            RCConversationType.ConversationType_CUSTOMERSERVICE.rawValue,
            RCConversationType.ConversationType_DISCUSSION.rawValue,
            RCConversationType.ConversationType_GROUP.rawValue,
            RCConversationType.ConversationType_PRIVATE.rawValue,
            RCConversationType.ConversationType_PUBLICSERVICE.rawValue,
            RCConversationType.ConversationType_SYSTEM.rawValue  
            ])
            self.refreshConversationTableViewIfNeeded()     
        })

可以显示出效果如下：
