swift NSDate AM and Pm Format [duplicate] - ios

Question

This question already has answers here:
NSDateFormatter- stringFromDate not returning AM/PM
(6 answers)
Closed 5 years ago.
To convert date and time, I have used this:
let formatter = NSDateFormatter()
formatter.calendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierISO8601)
formatter.locale = NSLocale(localeIdentifier: "en_US_POSIX")
formatter.timeZone = NSTimeZone(forSecondsFromGMT: 0)
formatter.dateFormat = "M/dd/yyyy, h:mm"
formatter.AMSymbol = "AM"
formatter.PMSymbol = "PM"
let dateString = formatter.stringFromDate(model.courseDate)
print(dateString)
If the course date is "courseDate = "2017-01-09 01:00:00 +0000";"
but I am getting like this in print:
1/09/2017, 1:00 with no any AM or PM.
How can I achieve this?
Thanks.

Answer 1

according to the date formatter specs
You can retrieve a date in 24h format instead of requesting AM/PM by using
HH instead of hh
so the date "21/11/2016 01:30" (pm) would be "21/11/2016 13:30".
if you do need to print the format, though, you can print it using:
a

As per Apple general date formatter you should use "M/dd/yyyy, hh:mm a" in your date format.
like : formatter.dateFormat = "M/dd/yyyy, hh:mm a"
Hope this will help you!

use following code may help full for you
//Call function
let dateTime = self.convertDateFormaterAamer(sendTimeStep, inputDateFormate: "dd-MM-yyyy HH:mm:ss", outputDateFormate: "dd-MMM-yyyy hh:mm a")
//Date function
func convertDateFormater(date: String,inputDateFormate: String , outputDateFormate: String) -> String
{
let dateFormatter = NSDateFormatter()
//dateFormatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
//dateFormatter.timeZone = NSTimeZone(name: "UTC")
dateFormatter.dateFormat = inputDateFormate
let date = dateFormatter.dateFromString(date)
//dateFormatter.dateFormat = "yyyy MMM EEEE HH:mm"
//dateFormatter.timeZone = NSTimeZone(name: "UTC")
dateFormatter.dateFormat = outputDateFormate
var timeStamp = ""
if (date != nil)
{
timeStamp = dateFormatter.stringFromDate(date!)
}
return timeStamp
}
