如何将此字符串“2016-04-14T10:44:00+0000”转换为NSDate并只保留年、月、日、小时?
中间的T真的让我在处理日期时不习惯。

在swift4,
var Msg_Date_ = "2019-03-30T05:30:00+0000"
let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd yyyy h:mm a" //"MMM d, h:mm a" for Sep 12, 2:11 PM
let datee = dateFormatterGet.date(from: Msg_Date_)
Msg_Date_ = dateFormatterPrint.string(from: datee ?? Date())
print(Msg_Date_)
//输出:- 2019年3月30日05:30 PM

在swift4,
var Msg_Date_ = "2019-03-30T05:30:00+0000"
let dateFormatterGet = DateFormatter()
dateFormatterGet.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let dateFormatterPrint = DateFormatter()
dateFormatterPrint.dateFormat = "MMM dd yyyy h:mm a" //"MMM d, h:mm a" for Sep 12, 2:11 PM
let datee = dateFormatterGet.date(from: Msg_Date_)
Msg_Date_ = dateFormatterPrint.string(from: datee ?? Date())

Swift 3.0 - 4.2
import Foundation
extension String {
func toDate(withFormat format: String = "yyyy-MM-dd HH:mm:ss")-> Date?{
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone(identifier: "Asia/Tehran")
dateFormatter.locale = Locale(identifier: "fa-IR")
dateFormatter.calendar = Calendar(identifier: .gregorian)
dateFormatter.dateFormat = format
let date = dateFormatter.date(from: self)
return date
}
}
extension Date {
func toString(withFormat format: String = "EEEE ، d MMMM yyyy") -> String {
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "fa-IR")
dateFormatter.timeZone = TimeZone(identifier: "Asia/Tehran")
dateFormatter.calendar = Calendar(identifier: .persian)
dateFormatter.dateFormat = format
let str = dateFormatter.string(from: self)
return str
}
}
创建全局函数
func convertDateFormat(inputDate: String) -> String {
let olDateFormatter = DateFormatter()
olDateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss"
let oldDate = olDateFormatter.date(from: inputDate)
let convertDateFormatter = DateFormatter()
convertDateFormatter.dateFormat = "MMM dd yyyy h:mm a"
return convertDateFormatter.string(from: oldDate!)
}
调用函数并在其中传递值
get_OutputStr = convertDateFormat(inputDate: "2019-03-30T05:30:00+0000")
这里是输出

这是一个简单的方法来获得一个字符串，并将其转换回字符串与日期的结构通过字符串扩展
日期字符串示例"2022-03-15T07:13:49.607+00:00"
如果日期的格式不是“yyyy-MM-dd'T hh:mm:ss”。SSSSSSSZ” 它将返回01-01-70
import Foundation
extension String {
func convertToDate() -> String {
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSSSSSZ"
if let dt = dateFormatter.date(from: self) {
dateFormatter.dateFormat = "MM-dd-yy"
let formatedStringDate = dateFormatter.string(from: dt)
return formatedStringDate
}
return "01-01-70"
}
}
就用SwifterSwift吧。
stringDate = "2020-04-26T08:56:17.987Z"
let date = Date(iso8601String: stringDate)
