  3 | # DateSuger
  4 | 
  5 | 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。
  6 | 
  7 | ## 要求
  8 | 
  9 | * iOS8 +
 10 | * Swift 2.0 +
 11 | 
 12 | ## 安装
 13 | 
 14 | ### Cocoapods
 15 | 
 16 | `pod 'DateSuger' `
 17 | 
 18 | ### 手动
 19 | 
 20 | 直接将Source目录下的swift文件导入到工程。
 21 | 
 22 | ## 使用
 23 | 
 24 | ### 日期编辑
 25 | 
 26 | 我们想获得当前时间十天后的NSDate对象，在Cocoa中是这么做的：
 27 | 
 28 | ```
 29 | let date1 = NSDate()
 30 | let components = NSDateComponents()
 31 | components.day = 10
 32 | let calenar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
 33 | let date2 = calenar?.dateByAddingComponents(components, toDate: date1, options: [])
 34 | ```
 35 | 
 36 | 在DateSuger里面一句话就可以代替：
 37 | 
 38 | ```
 39 | let date3 = NSDate().dateByAddingDays(10)
 40 | ```
 41 | 
 42 | 还想更简单吗？还能这样：
 43 | 
 44 | ```
 45 | let date4 = NSDate() + .Day(10)
 46 | ```
 47 | 
 48 | 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：
 49 | 
 50 | ```
 51 | let date5 = NSDate() + .Year(1) + .Month(3)
 52 | ```
 53 | 就是这么简单~
 54 | 
 55 | ### 日期信息
 56 | 
 57 | 如果我们要知道今天是几月，或是星期几，传统代码如下：
 58 | 
 59 | ```
 60 | let calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)
 61 | let components = calendar?.components([.Weekday,.Month], fromDate: NSDate())
 62 | let weekday = components?.weekday
 63 | let month = components?.month
 64 | ```
 65 | 通过DateSuger可以直接从NSDate实例中获取:
 66 | 
 67 | ```
 68 | let weekday = NSDate().weekday
 69 | ```
 70 | 
 71 | 支持的日期信息有：
 72 | 
 73 | |Component|
 74 | |---|
 75 | |Era|
 76 | |Year|
 77 | |Day|
 78 | |Hour|
 79 | |Minute|
 80 | |Second|
 81 | |Quarter|
 82 | |Weekday|
 83 | |WeekdayOrdinal|
 84 | |WeekOfMonth|
 85 | |WeekOfYear|
 86 | |DayOfYear|
 87 | 
 88 | 
 89 | ### 其他信息判断
 90 | 
 91 | DateSuger支持对一些常用信息的判断，通过实例代码展示：
 92 | 
 93 | ```
 94 | let v1 = NSDate().isInLeapYear 			// 判断是否是闰年
 95 | let v2 = NSDate().isToday				// 判断是否是今天
 96 | let v3 = NSDate().isTomorrow			// 判断是否是明天
 97 | let v4 = NSDate().isYesterday			// 判断是否是昨天
 98 | let v5 = NSDate().isSameDay(someDate)	// 判断是否和某日期在同一天
 99 | ```
100 | ### 快速创建NSDate
101 | 
102 | 能够通过指定年月日、小时、分钟、秒来创建NSDate
103 | 
104 | ```
105 | let date1 = NSDate.dateWithYear(2015, month: 3, day: 
106 | let date2 = NSDate.dateWithYear(2015, month: 3, day: 28, hour: 3, minute: 12, second: 12)
107 | ```
108 | 
109 | ### 日期比较
110 | 
111 | DateSuger 实现了`Comparable`协议，能够通过`==`,`>`,`<`,`>=`,`<=`来对日期进行比较。
112 | 
113 | ```
114 | if date1 > date2 {
115 | 	//...
116 | }
117 | if date1 >= date2 {
118 | 	//...
119 | }
120 | if date1 == date2 {
121 | 	//...
122 | }
123 | ```
124 | 
125 | ### 获得日期的时间差
126 | 
127 | Date Suger 能够快速的获取两个日期间隔的年数，天数等信息。
128 | 
129 | ```
130 | let years1 = NSDate.yearsFrom(date1, toDate: NSDate())
131 | let years2 = NSDate().yearsFrom(date1)
132 | ```
