I just recently started learning about core animation and am doing good so far, though actual tutorials are hard to find unlike cool examples that I don't understand a word of Anyways, I decided after getting it down pat to put simple core animation into an app I already have out. I set everything up with actions and outlets and layers being backed up so that each of the windows in the app will fade in and out when opened and closed. This works fine, I've tested it thoroughly, but it's causing a weird glitch. In each window I have a "close" button, and an "add" button among other things. Every window except for the starting window gets this weird problem where one of those buttons disappears. It's still there, you can click on it, but it becomes invisible. I've tried setting up personal outlets to those buttons to set them back to visible but that doesn't work. I've tried giving them a special layer on top of their being a sublayer and setting transparency to 1.0 but that doesn't work. I've tried moving and resizing them just in case but that didn't help. Can anyone help? oh I just found out resizing the window makes them appear.
