簡單的微信評(píng)論回復(fù)功能
先說說大概邏輯，一個(gè)控制器里添加列表(類似朋友圈的每條動(dòng)態(tài))，每個(gè)動(dòng)態(tài)里面再添加一個(gè)列表(用來顯示所有評(píng)論以及點(diǎn)擊回復(fù)評(píng)論)，都是用Masonry布局加HYBMasonryAutoCellHeight自適應(yīng)行高來完成，鍵盤是隨便找的一個(gè)第三方，而且項(xiàng)目里也沒重點(diǎn)設(shè)置
先看看大概的界面以及兩個(gè)模型里面的屬性

下面是viewController里面代碼，這里把回復(fù)的人的名字定死了，有數(shù)據(jù)的話可以根據(jù)實(shí)際情況來定

大致效果是這樣的

代碼寫的比較倉促，有什么寫的不對(duì)的大家可以評(píng)論，哈哈
有沒有大神愿意加我個(gè)小群，自己建的，只有3個(gè)人，都比較菜，如果哪位大神平時(shí)喜歡帶新人的話加我群:515385179 哈哈
