Only allow users to press UIButton once

Question

I am trying to design a interface of an app, and i would only like to allow the user to press a UIButton once to get the result. Is there any way i can lock the button after the button is pressed? And release the lock only when another button is pressed?

Thanks

Answer 1

You can set the button to be disabled once it is clicked:

- (IBAction)clicked:(id)sender {
    //See all buttons enabled
    //Try a loop or manually

    ((UIButton *)sender).enabled = NO;
}

Of course you can. Just use the property enabled of the UIButton. When the user presses it, set enabled to NO: [myButton setEnabled:NO];, and set YES when you need enable it again later.
