Use this bellow method with pass your Date...

       -(NSString *)StringFromDate:(NSString *)DateLocal{
        DateLocal = [self trimString:DateLocal];
        NSDateFormatter *dateFormatter = [[[NSDateFormatter alloc] init] autorelease];   
        [dateFormatter setDateFormat:@"EEE, dd LLL yyyy hh:mm:ss Z"];

        NSDate *date = [dateFormatter dateFromString: DateLocal];
        NSString *tt = [dateFormatter stringFromDate:date];
        NSDate *dateReturn = [dateFormatter dateFromString:tt];


        NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
        [dateFormat setDateFormat:@"EEE LLL dd yyyy hh:mm a"];
        NSString *dateString = [dateFormat stringFromDate:dateReturn];  
        NSLog(@"Date is HERE  =====>> %@",dateString);
        [dateFormat release];
        return dateString;
    }

Use this method. Pass your string into it & set Date format as desired. You will get your desired date in return.

- (NSDate *) getDateFromString:(NSString *) inputDate
{

    NSDateFormatter *dateForm = [[NSDateFormatter alloc] init];

    [dateForm setDateFormat:@"yyyy-MM-dd"];

    NSDate *dateSelected = [dateForm dateFromString:inputDate];

    [dateForm release];

    return dateSelected;
}

Hope it works for you.

NSString *dateStr = @"Tue, 25 May 2010 12:53:58 +0000";

// Convert string to date object
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setDateFormat:@"EE, d LLLL yyyy HH:mm:ss Z"];
NSDate *date = [dateFormat dateFromString:dateStr];

But First

  1. Create a NSDateFormatter to convert the date string to a NSDate object.
  2. Create a second NSDateFormatter (or change the format string of the first) to convert the NSDate back to a string.

Will this be a bit helpful ???

EDIT

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[dateFormatter setDateFormat:@"yyyy-MM-ddHH:mm:ss"];
NSDate *date = [dateFormatter dateFromString:@"2011-04-0600:28:27"];
