I am using the standard way of making shadows from a button programmatically, but I would like to shadow to no longer exist after I am done with the button. I could set opacity to 0, but would the shadow still exist and if so would it still tax the system. thanks
this gives an error
tempButton.superview.layer.shadowOffset = nil;
tempButton.superview.layer.shadowRadius = nil;
tempButton.superview.layer.shadowOpacity = nil;
I usually do the following to be safe.
[[tempButton layer] setShadowOpacity:0.0];
[[tempButton layer] setShadowRadius:0.0];
[[tempButton layer] setShadowColor:nil];
Quartz is highly optimized and will not waste any time rendering if it doesn't have to.
I would just remove the button, and replace it with an identical (but non-shadowed) button. Or keep both around and hide/unhide one of them. Sometimes it's easier to create a new UI object than munge around with an existing one.
