-(IBAction)choiceOne:(id)sender{

    if ([Choice2 isSelected]) {

        score = score -4;
        score = score+8;

}

I have to finish highlight’s from selected button if any other button is pressed from menu

- (void)doHighlight:(UIButton*)b {
    [b setHighlighted:YES];
}    
-(void)finishHighlight:(UIButton*)a{

    [a setHighlighted:NO];

}

these are the functions which I’m using in above … and

Answer 1

This would be super easy if both the buttons are connected to “IBOutlets”. Are they?
Like for example:

IBOutlet UIButton * mode1;
IBOutlet UIButton * mode2;

parameters a & b are ignored in this particular…

-(IBAction) button1Pressed:(id)sender {

    [self performSelector:@selector(highlightButton1:) withObject:sender afterDelay:0.0];
}

- (void)highlightButton1:(UIButton *)a { 
        [mode1 setHighlighted:YES];
    [mode2 setHighlited:NO];
}
-(IBAction) button2Pressed:(id)sender {

    [self performSelector:@selector(highlightButton2:) withObject:sender afterDelay:0.0];
}

- (void)highlightButton2:(UIButton *)b { 
    [mode1 setHighlighted:NO];
    [mode2 setHighlited:YES];
}
