Ok for this part you need an `NSDateFormatter“

NSDateFormatter *df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"EEE MM dd yyyy hh.mm a"];
NSDate *dateFromString =[df dateFromString:yourString];

Then find the time difference in Seconds between the 2.

NSTimeIntervall diffInSeconds = [dateFromString timeIntervalSinceNow];

This will calculate the seconds between the dateFromStringand now.
