Add this code to your project and comparing dates is easier than ever
扩展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调用就行了，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)
