Question

I have a problem. I have 3 text field for day, month, year to get date input from the user I do not want to use a date picker. Instead I create a string from all three inputs in the format dd/mm/yy and use a date formatter like so to assess the validity.

 NSDate *convertedDOB = [dobFormatter dateFromString:dateOfBirth];
if (convertedDOB == nil){
    NSLog(@"DATE EPIC FAIL");
}
else{ 
    NSLog(@"DATE OK");
}
[dobFormatter release];

If I enter something stupid like 10/40/88 it returns an error, however date of the type 40/12/88 or 30/02/88 go undetected. Is there anything I’m doing wrong? Thanks.

You should probably use NSDatePicker so that errors like this can be prevented.

Also, you may be getting nil as the date format entered is different to the date format of the NSDateFormatter.
