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

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.

This is the updated version of James Paolantonio's answer for Swift 4

@IBAction func clicked(_ sender: Any) {
    //See all buttons enabled
    //Try a loop or manually
    (sender as? UIButton)?.isEnabled = false
}

Just disable the Uibutton when your selector method for the button is called. as in [aButton setEnabled:False];, and when the user taps the other button reenable the first one and disable the second one as in [bButton setEnabled:False] and [aButton setEnabled:True],

hope it helps.

You need to have a reference to the first pressed button.. on the next press you can enable the old one and disable the new one

Button *disabledButton;
- (IBAction)clicked:(id)sender {        
   if (disabledButton)
     disabledButton.enabled = YES;

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

Only allow users to press UIButton once
