Question

how can i implement an NSArray in this method (instead of just defining each one of the objects).

code:

- (void) fadeOutShuffleAnimation
{
    [UIView beginAnimations:nil context:nil];
    [UIView setAnimationDuration: 0.8];
    [UIView setAnimationDelegate:self];
    juw1.alpha = 0.0;
    juw2.alpha = 0.0;
    juw3.alpha = 0.0;
    juw4.alpha = 0.0;
    ...
    [UIView commitAnimations];
}

Answer 1

if juw* are uiviews (or uiview subclasses) you can assign them unique tag property and loop through them like:

for (loop tag condition){
   [parentView viewWithTag: tag].alpha = 0;
}

So actually after you create your items and add to parentView as subviews you might not need to store items as you can always get them using their tags.
