on screen i have 2 buttons. when they are tapped, they become highlighted. i'm trying to make it so that only one button can be highlighted at once.
the above snippet evaluates all objects in the highlightsArray. if all of them have a zero alpha (IE no button has been tapped), it will highlight the sender button. but even with this code when one button is highlighted i can still press the other button and have them both highlighted. this code commands to only goto highlightPressedButton:sender if all highlights are currently of zero alpha!
any thoughts?
Code:
- (void)viewDidLoad
{
NSMutableArray *aHighlightsArray = [[NSMutableArray alloc] initWithObjects: buttonHighlight1, buttonHighlight2, nil];
self.highlightsArray = aHighlightsArray;
[aHighlightsArray release];
}
- (IBAction)menuTouchDown:(id)sender
{
for (id Objects in highlightsArray)
if ([Objects alpha] == 0.0)
[self highlightPressedButton:sender]
