Question

board[i] is an array of UIButtons that I have created programmmatically, and I can’t change their image for UIControlStateHighlighted:

    [board[i] setImage:[UIImage imageNamed:@"block"] forState:UIControlStateNormal];
    [board[i] setImage:[UIImage imageNamed:@"blockPressed"] forState:UIControlStateHighlighted];

When I press the button with the mouse in the simulator the image doesn’t change. I think this is a very noob question, but I don’t what the code doesn’t work.

Answer 1

when adding button programatically do this:

1. add target of each same.

2. provide tag all button from 0 to count.

3. set UserInteraction to true

4. setBackgroundImage:[UIImage imageNamed:@”blockPressed.png”] forState:UIControlStateHighlighted if u want button to be highlited

Now button is pressed same method is called for all button: For example

-(void)ButtonTouched:(id)sender
{
   UIButton *btntouched = sender;
   NSLog(@"%@", btntouched);
   [btntouched setBackgroundImage:[UIImage imageNamed:@"blockPressed.png"]  forState:UIControlStateHighlighted];// it can be forState:UIControlStateNormal also
}
