我有let time = "Jun 08, 2015 11:27 PM"
,使用以下代码将其转换为NSDate
let formatter = NSDateFormatter()
formatter.dateStyle = .MediumStyle
formatter.timeStyle = .ShortStyle
let date = formatter.dateFromString(time)
获得date as nil
,即使我尝试使用自定义格式化程序
//MMM dd, yyyy HH:mm a
//formatter.dateFromString("MMM dd, yyyy HH:mm a")
还没有工作,有什么遗失?

let time = "Jun 08, 2015 11:27 PM"
let formatter = NSDateFormatter()
formatter.dateFormat = "MMM dd, yyyy HH:mm a"
let date = formatter.dateFromString(time)
formatter.dateStyle = .MediumStyle
formatter.timeStyle = .ShortStyle
let newString = formatter.stringFromDate(date!)
NSLog("the newString %@", newString)
let newDate = formatter.dateFromString(newString)
NSLog("the date %@", newDate!)
输出
newString 2015年6月8日,下午12:27
日期 2015-06-08 06:57:00 +0000

我在Plyground中测试了以下内容并且它可以正常工作。
let time = "Jun 08, 2015 11:27 PM"
let formatter = NSDateFormatter()
formatter.dateFormat = "MMM dd, yyyy hh:mm a"
let date = formatter.dateFromString(time)

请尝试以下代码:
func dateformat()
{
let time = "Jun 08, 2015 11:27 PM"
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MMM dd, yyyy HH:mm a"
dateFormatter.timeZone = NSTimeZone(abbreviation: "UTC");
let date = dateFormatter.dateFromString(time)
println(NSDate.date())
}
