Question

OK so I thought this would be pretty simple but it’s tripping me up.. I’m sure i’m just missing something simple, but could you guys help me out? Im trying to change the alpha values of objects (uiimageviews) in an nsarray. So far i got:

for (int i=1; i < [alphaSet count]; i++) {
   [[alphaSet objectAtIndex:i] setAlpha:masterAlpha];
}

It just throws bad access… Any ideas?

Use NSLog to make sure your image views are there.

for (int i=1; i < [alphaSet count]; i++) {
   NSLog(@"At count %i there is this object: %@", i, [alphaSet objectAtIndex:i]);
   UIImageView *iv = [alphaSet objectAtIndex:i];
   iv.alpha = masterAlpha;
}
