英文:
Swift DateFormatter from String with (EEST)?
问题
我正在尝试解析来自API的字符串日期为Date()。
日期字符串是：31-07-2023 12:44 (EEST)
我的代码：
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy hh:mm (zzzz)"
if let ptdate = formatter.date(from: prayer.getString("time")) {
// 无法工作！
}
我相信我正在使用的日期格式dd-MM-yyyy hh:mm zzzz中缺少了一些内容，但我不确定是什么，因为我已经花了数小时搜索日期格式。
英文:
i am trying to parse string date which is coming from an API to Date().
the date string is: 31-07-2023 12:44 (EEST)
My code:
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy hh:mm (zzzz)" // "yyyy-MM-dd h:mm a"
if let ptdate = formatter.date(from: prayer.getString("time")) {
// Not working!
}
i believe there is something missing in date format i am using which is dd-MM-yyyy hh:mm zzzz, i am not sure what it is, since i've spent hours googling date formats.

let dateString = "31-07-2023 12:44 (EEST)"
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy' 'HH:mm' ('z')"
if let ptdate: Date = formatter.date(from: dateString) {
print(ptdate)
}
英文:
For the dateFormat string you need to:
- Escape all string content with '
- Use 24h time format
- Use time zone specific non-location field code "z" (equivalents are: zz, zzz, zzzz)
let dateString = "31-07-2023 12:44 (EEST)"
let formatter = DateFormatter()
formatter.dateFormat = "dd-MM-yyyy' 'HH:mm' ('z')"
if let ptdate: Date = formatter.date(from: dateString) {
print(ptdate)
}

我是你的中文翻译，以下是翻译好的部分：
我是这样做的（不需要日期格式化器）：
let dateString = "31-07-2023 12:44 (EEST)"
let format: Date.FormatString = "\(day: .twoDigits)-\(month: .twoDigits)-\(year: .defaultDigits) \(hour: .twoDigits(clock: .twentyFourHour, hourCycle: .oneBased)):\(minute: .twoDigits) (\(timeZone: .specificName(.short)))"
var strategy = Date.ParseStrategy.fixed(format: format, timeZone: .current)
let date = try? Date(dateString, strategy: strategy)
请注意，我已经将 HTML 编码字符 " 转换为正常的双引号。如果你有任何其他需要或问题，请随时提出。
英文:
I did it like this (no date formatter needed):
let dateString = "31-07-2023 12:44 (EEST)"
let format: Date.FormatString = "\(day: .twoDigits)-\(month: .twoDigits)-\(year: .defaultDigits) \(hour: .twoDigits(clock: .twentyFourHour, hourCycle: .oneBased)):\(minute: .twoDigits) (\(timeZone: .specificName(.short)))"
var strategy = Date.ParseStrategy.fixed(format: format, timeZone: .current)
let date = try? Date(dateString, strategy: strategy)

"EEST"是一个标准的时区缩写，因此您应该使用 zzz，并且我也假设时间格式是24小时制，所以配置日期格式化程序如下：
formatter.dateFormat = "dd-MM-yyyy HH:mm (zzz)"
更新：
似乎单个 z 也可以工作："dd-MM-yyyy HH:mm (z)"。
英文:
"EEST" is a standard time zone abbreviation so you should use zzz and I also assume that the time format is 24h so configure the date formatter like this
formatter.dateFormat = "dd-MM-yyyy HH:mm (zzz)"
Update
Seems like a single z also works "dd-MM-yyyy HH:mm (z)"
