如何分类NSMutableArray iPhone？

Question

我有一个方案，其中应用程序从json php检索信息到NSMutableArray 。 我的问题如下； 如何按“时间”字段对元素进行排序？ 另外，我如何仅将具有“ day”的元素显示为“ monday”？ （如果if语句看起来像什么？）。 感谢您对此的任何帮助。

NSMutableArray的信息也如下所示；

   Array: (
            {
            Code = 2COS402;
            Core = Yes;
            Credit = 15;
            Day = Monday;
            Facilities = Full;
            Level = 4;
            Module = "Introduction to Computer Programming";
            "Room_Empty" = Yes;
            Teacher = "Mark James";
            Time = "10:45";
            id = 1;
        },
            {
            Code = 2GDP401;
            Core = Yes;
            Credit = 15;
            Day = Monday;
            Facilities = Full;
            Level = 4;
            Module = "Fundamentals of Interactive Games";
            "Room_Empty" = No;
            Teacher = "Will Smith";
            Time = "09:00";
            id = 4;
        },
            {
            Code = 2GDP501;
            Core = Yes;
            Credit = 15;
            Day = Monday;
            Facilities = Full;
            Level = 4;
            Module = "Games Play Design";
            "Room_Empty" = Yes;
            Teacher = "Frank Sinatra";
            Time = "15:00";
            id = 6;
        }
    )

Answer 1

您可以检查NSMutableArray sortUsingComparator：或sortUsingSelector：方法。 当然，您需要定义您的自定义NSComparator或实现自定义方法。
