How to get current time as a String (not as Date)
date time format.
yyyy-MM-dd HH:mm:ss
回答1:
This is the way I figure it out.
// Get today date as String
func getTodayString() -> String{
let date = Date()
let calender = Calendar.current
let components = calender.dateComponents([.year,.month,.day,.hour,.minute,.second], from: date)
let year = components.year
let month = components.month
let day = components.day
let hour = components.hour
let minute = components.minute
let second = components.second
let today_string = String(year!) + "-" + String(month!) + "-" + String(day!) + " " + String(hour!) + ":" + String(minute!) + ":" + String(second!)
return today_string
}
let today : String!
today = getTodayString()

To get time as String you should use DateFormatter, something like this, sorry if there some mistakes, I wrote it right here
let dateFormatter : DateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let date = Date()
let dateString = dateFormatter.string(from: date)
let interval = date.timeIntervalSince1970
