将具有.000Z的日期字符串格式化为NSDate [英] Format date string with .000Z into NSDate

问题描述

我想将日期字符串格式化为NSDate对象，这听起来好像没什么大不了的.

I would like to format a date string into a NSDate object, which doesn't sound like a big thing.

重点是，日期字符串在时区值中包含一个点，而不是加号或其他内容.日期看起来像这样:

The point is, that the date string contains a dot in the timezone value instead of a plus or something else. A date looks like this:

2017-06-04T16:00:00.000Z

我尝试了格式字符串，例如

I tried format strings like

yyyy-MM-dd'T'HH:mm:ss.ZZZZ
yyyy-MM-dd'T'HH:mm:ss.ZZZ
yyyy-MM-dd'T'HH:mm:ss.Z

当然，我也在 nsdateformatter.com 上进行了检查，该方法可以工作，但在xCode中NSDate始终为nil.

Of course I've also checked it on nsdateformatter.com, which works but in xCode the NSDate is always nil.

推荐答案

对我有用

var str = "2017-06-04T16:00:00.000Z"
let formato = DateFormatter()
formato.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
formato.timeZone = NSTimeZone(name: "UTC")! as TimeZone
formato.formatterBehavior = .default
var data = formato.date(from: str)
