我有一个NSMuableArray，每个字符串包含大量信息（我知道它不是最好的方式，但是它是如何做的）所以每个字符串看起来像
02:00:00-21:00:00-June 3th, 2014-23:00:00-June 3th, 2014||VincentKahn.com||10.00
我想在第一个日期，2014年6月21日 - 2014年6月3日部分（我知道有拼写错误）对其进行排序，我已经看过NSSortDescriptor的例子，但我不是有一个约会，我仍然需要保留所有信息。
我试过拆分它，但是每次循环都是如此，如果我这样做了，我知道我将失去我需要的格式。
最快捷的方式是什么？对此进行排序？
如果它有助于我为TableView
排序编辑：
我检索保存在打开为可变数组的.plist中的这些字符串
答案 0 :(得分：0)
复杂的方法，但我最终使用了一个使用块的三重排序系统（我认为这就是名称）按日排序，然后按月排序。
