時(shí)間格式化 根據(jù)上傳的時(shí)間戳對(duì)應(yīng)的字符串,
跟當(dāng)前時(shí)間做對(duì)比, 24小時(shí)內(nèi)顯示 : xx小時(shí)前/xx分鐘前/剛剛.
24小時(shí)-48小時(shí)顯示:昨天.
48小時(shí)-72小時(shí)顯示:前天
超過(guò)72小時(shí)顯示對(duì)應(yīng)日期 和 時(shí)間: 2016-04-05 13:23

注意:返回的 update_at時(shí)間戳 是否是多少位,如果包含后面3個(gè)0,需要用 [update_at longlongValue]
且 要 [update_at longlongValue] / 1000 .
