i have several views that are added and replaced by a main window using core animation... i've noticed that the text (label objects, checkbox text, etc.) in each view is not being anti-aliased. this link ( http://att.macrumors.com/attachment.php?attachmentid=147663&d=1228770137 ) will show you an image displaying this problem. the window on the left is from within Interface Builder (anti-aliased text), the window on the right is the running build (text with aliasing). how can i solve this problem? it's kinda surprising that it's not anti-aliasing the text automatically. hopefully there's some option i'm just forgetting to check off.
Assuming your text is always going to be drawn on top the window, the simple fix is to check the "Draws Background" property of your text field in IB, and then choose the windowBackgroundColor from the Developer palette in the color picker.
What's going on is this: the text is (normally) antialiased, but what is not active is subpixel antialiasing, which is what Quartz calls "font smoothing." The problem is that subpixel antialiasing requires that the text know the background color that it is drawing onto at the time it is drawn. But CoreAnimation renders everything into separate layers, and then composites them all together.
