Question

我想获得当前日期为SEP 15,2015。我尝试首先从NSDate中删除时间

  let calendar = NSCalendar.currentCalendar()
  let components = calendar.components(.CalendarUnitDay | .CalendarUnitMonth | .CalendarUnitYear, fromDate: date)
  let currentdate = NSCalendar.currentCalendar().dateFromComponents(components)
  println(currentdate)

然而，这并没有截断时间也使用了这个方法，它给了我个别的组件

let date = NSDate()
let calendar = NSCalendar.currentCalendar()
let components = calendar.components(.CalendarUnitDay | .CalendarUnitMonth | .CalendarUnitYear, fromDate: date)
let year =  components.year
let month = components.month
let day = components.day
let monthname = components.weekday

但问题是我使用第二种方法获得了int中的月份。我希望将1作为January进行通信。我如何实现我的结果？

Answer 1

您可以使用NSDateFormatter格式化您的日期

let formatter = NSDateFormatter()
formatter.dateFormat = "MMM dd,yyyy"
print(formatter.stringFromDate(NSDate()))

Answer 2

以下是以所需格式打印当前日期的代码：

*(&y + 1)

Answer 3

对不起这个问题..我应该了解dateFormatter。我从号码获得了月份名称，所以问题解决了，但是如果有更好的方法可以做到这一点。请说

    let date = NSDate()
    let calendar = NSCalendar.currentCalendar()
    let components = calendar.components(.CalendarUnitDay | .CalendarUnitMonth | .CalendarUnitYear, fromDate: date)

    let year =  components.year
    let month = components.month
    let day = components.day

    let dateFormatter: NSDateFormatter = NSDateFormatter()
    let months = dateFormatter.shortMonthSymbols
    let monthSymbol = months[month-1] as! String
    println(monthSymbol)

从NSDate SWIFT截断时间
