如何在 tableview 中将 JSON 字符串更改为日期格式 [英] How to change JSON string to date format in tableview

问题描述

我正在使用 tableView 显示 JSON 数据，我想在 tableView 单元格中将 JSON 字符串转换为日期格式.

I'm displaying JSON data using a tableView and I want to convert JSON string to date format in tableView cell.

字符串格式的 JSON 日期:

My JSON date in string format:

"createdDate": "2018-08-16 11:34:59"

我想把它转换成日期格式在 cellForRowAt 函数中.

I want to convert it into date format in cellForRowAt function.

struct JSONInfo: Decodable {
    let createdDate: String
}

在我的 cellForRowAt 函数中:

cell.Date.text = JSONList[indexPath.row].createdDate

let createdDate = JSONlist[indexPath.row].createdDate
let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
let date = dateFormatter.date(from: createdDate)
dateFormatter.dateFormat = "dd/MM/yyyy"
let IssuedDate = dateFormatter.string(from:date!)

let lastDate = JSONlist[indexPath.row].dueDate
let dateFormatters = DateFormatter()
dateFormatters.locale = Locale(identifier: "en_US_POSIX")
dateFormatters.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatters.timeZone = TimeZone(secondsFromGMT: 0)
let dates = dateFormatter.date(from: lastDate)
dateFormatter.dateFormat = "dd/MM/yyyy"
let DueDate = dateFormatter.string(from:dates!)

它在 lastdate 中出错.我在这里收到错误:

It's getting error in lastdate. I get the error here:

let DueDate = dateFormatter.string(from:dates!)

推荐答案

您要转换成哪种格式.用你想要的格式试试这个

In which format do you want to convert. Try this one with your desired format

if let dateString = JSONList[indexPath.row].createdDate{

let dateFormatter = DateFormatter()
dateFormatter.locale = Locale(identifier: "en_US_POSIX")
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)
let date = dateFormatter.date(from: dateString)
dateFormatter.dateFormat = "dd/MM/yyyy"
let dateStr = dateFormatter.string(from:date!)

cell.Date.text = dateStr

}
