Change the background color of a button

Question

I have code that counts upwards when buttons on my app are pressed, but I'd also like to change the button's background color once it has been tapped.

Can I simply add a backgroundColor to the below code?

- (IBAction)buttonPressed {
count++;
totalLabel.text = [NSString stringWithFormat:@"Hours\n%li",(long)count];
}
@end

Sure. The easiest thing to do is change your IBAction so it receives the button that's been tapped.

-(IBAction)buttonPressed:(UIButton*)button {
   button.backgroundColor = [UIColor redColor];
}

(You'll need to reconnect the outlet from the nib as well so it knows that the new selector is buttonPressed:, not just buttonPressed.
