Date Conversion in objective c?

I have an array containing the String objects with this format 22/04/2011.My question is that how can I change this string into the yyyy-mm-dd format. I am using NSDateFormatter but it's not开发者_如何学编程 working.

The real thing to know that when you convert a string date to NSDate using NSDateFormatter using any of the above mentioned methods, you will always get the NSDate object in Local TimeZone. So when coding the method for date conversion you need to consider this factor.

Hope this helps..

Try this,

 NSDateFormatter *formater = [[NSDateFormatter alloc] init];
        [formater setDateFormat:@"dd/mm/yyyy"];
        NSDate *date2 = [formater dateFromString:@"22/04/2011"];
        [formater setDateFormat:@"yyyy-mm-dd"];
        NSString *result = [formater stringFromDate:date2];
NSLog(@"Date - %@",result);

Here how I do this ... This code works ... Try this

NSDate* currentDate = [NSDate date];
NSDateFormatter* df = [[NSDateFormatter alloc] init];
[df setDateFormat:@"yyyy-mm-dd"];
NSString* currentDateString = [df stringFromDate:currentDate];
[df release];

   NSDateFormatter *formater = [[NSDateFormatter alloc] init];
    [formater setDateFormat:@"dd/mm/yyyy"];
    NSDate *date2 = [formater dateFromString:@"2010-11-17"];
    [formater setDateFormat:@"yyyy-mm-dd"];
    NSString *result = [formater stringFromDate:date2];
