Question

您好，我正在尝试将年，月日期转换为毫秒，该怎么做，请帮助我做到这一点，

是我尝试过的代码。

let date:String = "2018-08-04T07:34:15.287Z"
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "yyyy-MM-dd"

var dateFromString = Date()
if let aString = dateFormatter.date(from: date) {
    dateFromString = aString
}

let timeInMiliseconds:Int = Int(TimeInterval(dateFromString.timeIntervalSince1970 * 1000))

return timeInMiliseconds

但是我总是将DateTime设置为毫秒。当我尝试将唯一的日期设为毫秒时，请帮助我需要帮助。预先感谢。

您的dateFormat与日期不匹配。尝试以下代码：

let date:String = "2018-08-04T07:34:15.287Z"
let dateFormatter = DateFormatter()
dateFormatter.timeZone = TimeZone.current
dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"

dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
let dateToConvert = dateFormatter.date(from: date)

dateFormatter.dateFormat = "yyyy-MM-dd"
let finalDate = dateFormatter.string(from: dateToConvert!)

var dateFromString = Date()
if let aString = dateFormatter.date(from: finalDate) {
    dateFromString = aString
}

let timeInMiliseconds:Int = Int(TimeInterval(dateFromString.timeIntervalSince1970 * 1000))

您将在timeInMiliseconds中获得1533321000000
