Did you set the contentsScale on your CATextLayer (or wrap it in a UIView)? By default CALayers never change their contentsScale, so if you are just using a plain CATextLayer without anything else to manage it, the contentsScale will be 1 regardless of the screen's density, making for fairly ugly text on Retina displays. -- David Duncan _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
