DateSuger

DateSuger 是一个优化Cocoa时间、日期使用方式的组件。Cocoa的 NSDate、NSDateComponent，NSCalendar等类提供了极其强大的日期处理的功能，但是使用起来却十分繁琐。DateSuger就是基于Swift2.0语言的对日期处理逻辑的一系列的语法糖。

要求

iOS8 +
Swift 2.0 +

安装

Cocoapods

pod 'DateSuger'

手动

直接将Source目录下的swift文件导入到工程。

使用

日期编辑

我们想获得当前时间十天后的NSDate对象，在Cocoa中是这么做的：

let date1 = NSDate()
let components = NSDateComponents()
components.day = 10
let calenar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let date2 = calenar?.dateByAddingComponents(components, toDate: date1, options: [])

在DateSuger里面一句话就可以代替：

let date3 = NSDate().dateByAddingDays(10)

还想更简单吗？还能这样：

let date4 = NSDate() + .Day(10)

这样相比于传统的Cocoa的接口，更加易用和容易理解。计算1年零3个月之后：

let date5 = NSDate() + .Year(1) + .Month(3)

就是这么简单~

日期信息

如果我们要知道今天是几月，或是星期几，传统代码如下：

let calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
let components = calendar?.components([.Weekday,.Month], fromDate: NSDate())
let weekday = components?.weekday
let month = components?.month

通过DateSuger可以直接从NSDate实例中获取:

let weekday = NSDate().weekday

支持的日期信息有：

Component
Era
Year
Day
Hour
Minute
Second
Quarter
Weekday
WeekdayOrdinal
WeekOfMonth
WeekOfYear
DayOfYear

其他信息判断

DateSuger支持对一些常用信息的判断，通过实例代码展示：

let v1 = NSDate().isInLeapYear 			// 判断是否是闰年
let v2 = NSDate().isToday				// 判断是否是今天
let v3 = NSDate().isTomorrow			// 判断是否是明天
let v4 = NSDate().isYesterday			// 判断是否是昨天
let v5 = NSDate().isSameDay(someDate)	// 判断是否和某日期在同一天

快速创建NSDate

能够通过指定年月日、小时、分钟、秒来创建NSDate

let date1 = NSDate.dateWithYear(2015, month: 3, day: 
let date2 = NSDate.dateWithYear(2015, month: 3, day: 28, hour: 3, minute: 12, second: 12)

日期比较

DateSuger 实现了Comparable协议，能够通过==,>,<,>=,<=来对日期进行比较。

if date1 > date2 {
	//...
}
if date1 >= date2 {
	//...
}
if date1 == date2 {
	//...
}

获得日期的时间差

Date Suger 能够快速的获取两个日期间隔的年数，天数等信息。

let years1 = NSDate.yearsFrom(date1, toDate: NSDate())
let years2 = NSDate().yearsFrom(date1)
