iOS開發(fā)集成騰訊云IM即時通訊

最近做的項目里公司說明確要用騰訊云的IM,傳送門：https://cloud.tencent.com/product/im?fromSource=gwzcw.471467.471467.471467但两，剛開始集成會發(fā)現(xiàn)有很多坑點，下面讓我們一步一步來集成：
首先 podfile加入：

pod 'TXIMSDK_iOS'

pod install一下就會發(fā)現(xiàn) 騰訊云的通訊基礎(chǔ)SDK已經(jīng)被引入進來了频鉴，可以進行socket連接互相發(fā)送消息了销斟，但是UI框架是沒有的祭玉，所以還是得去下載他的demo去研究一波箱熬，
馁害，將下面這個TUIKit工程拖入項目文件目錄下：

屏幕快照 2019-03-23 下午5.07.12.png

首先選擇TUIKit的target編譯一波窄俏，然后退出Xcode，然后再編譯一波自己的工程target碘菜，如果不報錯凹蜈，那就可以集成進去了，注意忍啸，這里如果報錯的話仰坦，幾乎都是framework路徑設(shè)置引用問題，自己直接去search path設(shè)置那里面看就行计雌。
通常做IM最核心的東西人家已經(jīng)給我們做好了悄晃，接下來就是自定義氣泡消息了，這里得看懂他代碼是怎么寫的白粉，進去你會發(fā)現(xiàn)有幾個基類的類：我們要做的就是重寫那幾個基類就行：
