在Swift中将字符串“2016-09-02 12:25:08”转换为2016-09-02 12:25:08

Question

我有一系列带有键和值的词典。我需要根据日期格式降序排序一系列字典，比如formate 2016-09-02 12:25:08。

Answer 1

以下是按日期排序ArrayOfDictionary的可能解决方案：

    let sortedRostersByDate  = TempArray.sortedArray(comparator: { (obj1, obj2) -> ComparisonResult in


                        var date2:NSDate!
                        var date1:NSDate!

                        if let dict = obj2 as? NSDictionary
                        {
                            if let tempdate2 = df.date(from: dict.object(forKey: "Sectiontitle") as! String)
                            {
                                date2 = tempdate2 as NSDate!
                            }
                        }
                        if let dict = obj1 as? NSDictionary
                        {
                            if let tempdate1 = df.date(from: dict.object(forKey: "Sectiontitle") as! String)
                            {
                                date1 = tempdate1 as NSDate!
                            }
                        }
                        return date2.compare(date1 as Date)


                    })
let SortedArray = NSMutableArray(array: sortedRostersByDate)

这里TempArray是要排序的数组
