Question

I am trying to force a user to select a date in the future with a date picker. I obviously used the compare: method, however, when I do the following code, even if it’s the same date as [NSDate date], it tells the executes the if statement. Here is my code:

    if ([datePicker.date compare:[NSDate date]] == NSOrderedAscending) // If the picked date is earlier than today
{
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Hmm, this date is earlier than today" 
                                                    message:@"The date you've selected is earlier than today's date, please pick another" 
                                                   delegate:nil  
                                          cancelButtonTitle:@"Okay, I'll pick another" 
                                          otherButtonTitles:nil];
    // Show the alert
    [alert show];

    // Release the alert
    [alert release];
}

I don’t know the answer to your problem, but how you could circumvent it.

Just use the minimumDate property of the UIDatePicker, that’s even a much cleaner approach.
