Answer 1

试试这个，

swift 3.0

let dateStr = "2017-01-03T10:45:00.000+02:00"

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd\'T\'HH:mm:ss\'.000\'z"
dateFormatter.timeZone = NSTimeZone(name: "UTC") as TimeZone!
let date = dateFormatter.date(from: dateStr)

print("Date from String : \(date)")

dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss xxxx'"
dateFormatter.timeZone = NSTimeZone(forSecondsFromGMT: 7200) as TimeZone!

print("String From Date : \(dateFormatter.string(from: date!))")

结果:

字符串中的日期:可选(2017-01-03 08:45:00 +0000)

字符串开始日期:2017-01-03 10:45:00 +0200
