IOS仿QQ空間時間顯示

標籤：qq空間時間顯示

最近項目有類似QQ空間展示動態UI，模仿了QQ空間的時間顯示，在此記錄，以備查閱。

這是QQ空間的ui：

時間顯示為：

 1.今天－－>今天 xx:xx(今天 15:39)

  2.昨天－－>昨天 xx:xx(昨天 06:00)

  3.前天－－>前天 xx:xx(前天 19:00)

  4.同一年, 例如:同一年的一月三號－－>01-03 xx:xx(01-03 12:29)

  5.不在同一年 －－> xxxx-xx-xx(2014-12-12)

程式運行效果如下，以下為簡單的測試，沒有ui介面:

下面的代碼是在網上已有代碼的基礎上更改而來，原代碼點此查看
