In Cocoa, why won't a textfield be shown until after the IBAction is completely executed?

nib

I have an IBAction with some simple code inside:

-(IBAction)change:(id)sender {
[textfield setHidden:NO];
[self dolengthyaction];

}

'textfield' is an NSTextField in a nib file, and -'dolengthyaction' is a function that takes about a minute to finish executing.

My question is: Why isn't the textfield shown until AFTER "dolengthyaction" is done executing? I want it to be revealed before the dolengthyaction starts taking place. Is this an inherent problem or is there something wrong with my code? (or in another part of my code?)

I'm still not very good at programming so I apologize if I worded something badly and formatted something wrong.
