【Swift】日期比較函數 記錄下 Comparing date in Swift

Add this code to your project and comparing dates is easier than ever

擴充NSDATE

extension NSDate{ func isGreaterThanDate(dateToCompare : NSDate) -> Bool { var isGreater = false if self.compare(dateToCompare) == NSComparisonResult.OrderedDescending   { isGreater = true }   return isGreater } func isLessThanDate(dateToCompare : NSDate) -> Bool { var isLess = false if self.compare(dateToCompare) == NSComparisonResult.OrderedAscending   { isLess = true }   return isLess }  func addDays(daysToAdd : Int) -> NSDate {   var secondsInDays : NSTimeInterval = Double(daysToAdd) * 60 * 60 * 24   var dateWithDaysAdded : NSDate = self.dateByAddingTimeInterval(secondsInDays)   return dateWithDaysAdded }  func addHours(hoursToAdd : Int) -> NSDate {   var secondsInHours : NSTimeInterval = Double(hoursToAdd) * 60 * 60   var dateWithHoursAdded : NSDate = self.dateByAddingTimeInterval(secondsInHours)   return dateWithHoursAdded }}

It’s easy to use. Here’s a couple of examples

在.SWIFT調用就行了，EASY的很！

 

var today = NSDate()var oneHourFromNow = today.addHours(1)if today.isGreaterThanDate(oneHourFromNow) {  println("Something is terrebly wrong.")}var aWeekFromNow = today.addDays(7)
