NSString to NSDate
NSString *dateString = @"01-02-2010";
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// this is imporant - we set our input date format to match our input string
// if format doesn't match you'll get nil from your string, so be careful
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *dateFromString = [[NSDate alloc] init];
// voila!
dateFromString = [dateFormatter dateFromString:dateString];
NSDateFormatter *otherFormatter = [[NSDateFormatter alloc] init];
[otherFormatter setDateFormat:@"yyyy-MM-dd"];
//[otherFormatter setTimeStyle:NSDateFormatterMediumStyle];
NSString *resultString = [otherFormatter stringFromDate:dateFromString];
NSLog(@"%@", resultString);
And then you can convert it back to an NSDate or keep as an NSString.
