I have referred lot of links but could not find the solution hence asking it again.I have string which i need to convert into date format. Below is example

Input string : "1410271500" In above string 14 is for 2014

            10 is for Oct

            27 is day

Output string : "2014-10-27 03:00:00"

do like

NSString *getMilliSec = @"1410271500";
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:@"yyMMddHHmm"];
NSDate *getDate = [formatter dateFromString:getMilliSec];
[formatter setDateFormat:@"yyyy-MM-dd hh:mm:ss a"]; // or use yyyy-MM-dd hh:mm:ss
formatter.timeZone = [NSTimeZone systemTimeZone]; // optional
NSString *stringFromDate = [formatter stringFromDate:getDate];

swift3

 let getMilliSec = "1410271500"
    let formatter = DateFormatter()
    formatter.dateFormat = "yyMMddHHmm"
    let getDate = formatter.date(from: getMilliSec)
    formatter.dateFormat = "yyyy-MM-dd hh:mm:ss a" // or use yyyy-MM-dd hh:mm:ss
    formatter.timeZone = NSTimeZone.system // optional
    var stringFromDate = formatter.string(from: getDate!)

output
