I hope this helps you . Do you know all of the possible formats? You could always try creating an NSDateFormatter for each one, then trying a string until a valid date is returned. That's pretty kludgy, but might be better than nothing.

To fix this issue This question was asked a lot, but I can't find the solution for my problem. , this is working well for me, you might use it:
code :
NSString *startDateString = @"Tue, 31 Jul 2012 10:15:00 GMT"; //in real from a server

NSDateFormatter *formatter = [[NSDateFormatter alloc]init];
[formatter setTimeZone:[NSTimeZone timeZoneWithName:@"GMT"]];
[formatter setDateFormat:@"EEE, dd MMM yyyy HH:mm:ssZZZ"]; // SPOT the difference in this line

NSDate *startDate = [formatter dateFromString:startDateString];
[formatter setDateFormat:@"yyy-MM-dd HH:mm:ssZZZ"]; // and SPOT the difference in this line

NSString *endDateString = [formatter stringFromDate:startDate];
NSDate *endDate = [formatter dateFromString:endDateString];

NSLog(@"%@", endDate);

like below fixes the issue Convert to NSString, first NSTimeInterval then create NSString object and do what you want.
Convert to NSDate, first convert it to NSTimeInterval(double value) and create a NSDate object
code :
NSDate *date = [NSDate date]; 
//        convert to NSString
NSString *strValue = [NSString stringWithFormat:@"%f", [date timeIntervalSince1970]]; 

//        convert to NSDate
date =  [NSDate dateWithTimeIntervalSince1970:[strValue doubleValue]];
