ios - 距另一个日期一年的日期

Question

我正在尝试计算距当前日期一年后的日期:

let calendar = NSCalendar.currentCalendar()
let currDate = NSDate()
let newDate = calendar.dateBySettingUnit(.Year, value: 2017, ofDate: currDate, options: NSCalendarOptions(rawValue: 0))!

但是 newDate 始终是 2017 年 1 月 1 日。

Answer 1

你差不多明白了

let calendar = NSCalendar.currentCalendar()
let currDate = NSDate()
let newDate = calendar.dateByAddingUnit(.Year, value: 1, toDate: currDate, options: [])
