I made a button using Interface Builder and linked it to an action. I'd like to disable the *hit* button on the `if` statement below.

```
- (IBAction)hit:(id)sender {
    Application *app = [[Application alloc] init];
    int nc = [app dealCard];
    [userOne setIntValue:tu];
    [userTwo setIntValue:nc];
    tu += nc;
    [totalUser setIntValue:tu];
    BOOL bust = [app checkBust:tu];
    if (bust == YES) {
        [console setIntValue:1];
        //Disable button here.
    }
}

```

What should I do?
