How to convert date string into format "17 Nov 2010" - iphone

Question

I have the date that is in format 2010-11-17.This is of the form NSString.
I want to convert this NSString date into format 17 Nov 2010 and display in a label
This date is just not the current date but may even be the older dates.
So I cant use the [NSDate date] instance to get the date.
I tried using NSDateFormatter with the method dateFromString.
But it gives me a null value.
Here is the code snippet
NSString *dates = #”2010-11-16”;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd MMM yyyy"];
NSDate *dates1 = [dateFormatter dateFromString:dates];
NSString *dates2 = [dateFormatter stringForObjectValue:dates1];
NSLog(#"dates : %#",dates);
NSLog(#"Dates 2 : %#",dates2);
[dateLabel setText:dates2];
NSLog(#"Formatted Date is : %#",dateLabel.text);
What should be done?
Please Help and suggest.
Thanks.

Answer 1

Try this
NSDateFormatter *formater = [[NSDateFormatter alloc] init];
[formater setDateFormat:#"yyyy-MM-dd"];
NSDate *date2 = [formater dateFromString:#"2010-11-17"];
[formater setDateFormat:#"d MMM yyyy"];
NSString *result = [formater stringFromDate:date2];
NSLog(#"RESULT %#",result);
I got the result.Correct me if this approach is wrong.

NSDateFormatter uses date format patterns from UNICODE.
So for your 17 Nov 2010 date you need something like this:
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateFormat:#"d MMM yyyy"];
NSString *result = [formatter stringForObjectValue:date];
Where date variable contains the date you'd like to format.
UPDATE: Try changing your code to this:
NSString *dates = #”2010-11-16”;
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"yyyy-MM-dd"];
NSDate *dates1 = [dateFormatter dateFromString:dates];
[dateFormatter setDateFormat:#"dd MMM yyyy"];
NSString *dates2 = [dateFormatter stringForObjectValue:dates1];
NSLog(#"dates : %#",dates);
NSLog(#"Dates 2 : %#",dates2);
[dateLabel setText:dates2];
NSLog(#"Formatted Date is : %#",dateLabel.text);
