I'm trying to format a date from a string into another format.
For example: 2012-05-29 23:55:52
into 29/05 *newline* 2010
.
I just don't get the logics behind NSDate and NSDateFormatter, I think..
Any help will be appreciated. Thanks :)
You will need to create an NSDateFormatter, and then set it's dateFormat to match the first date you have, eg:
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
That will set your date formatter to recognise your date string. You can then obtain an NSDate object from this using
NSDate *myDate = [dateFormatter dateFromString:myDateString]; // myDateString is the 2012-05-29 23:55:52 string
This gives you a full NSDate object representing that date. Now you need to reformat the date and turn it back into a string, so set the dateFormat on your formatter to the new format, and get a new string representation of the returned date:
[dateFormatter setDateFormat:@"dd/MM\nyyyy"];
NSString *newlyFormattedDateString = [dateFormatter stringFromDate:myDate];
[dateFormatter release], dateFormatter = nil;
And voila! You have your new date :)
