我希望通过user_Last_Update_Info

对此数组进行排序

怎么做？

Answer 1

这应该有所帮助：

protected override void ConfigureContainer()
{
    base.ConfigureContainer();
    . . . . .
    // What code must I write here?
    . . . . .
}

Answer 2

试试这个：

arrayToSort.sortUsingComparator{
    (obj1:AnyObject!, obj2:AnyObject!) -> NSComparisonResult in
    var dateStr1 = obj1["user_Last_Update_Info"] as NSString
    var date1: NSDate = dateFormatter.dateFromString(dateStr1)!
    var dateStr2 = obj2["user_Last_Update_Info"] as NSString
    var date2: NSDate = dateFormatter.dateFromString(dateStr2)!
    return date2.compare(date1)
}
