Question: I am having a problem with a UITextField's text being blurred/anti-aliased even with a standard font size. The text will appear crisp when the control is the first responder, but blurred again when it loses focus:

Does anybody know how to fix this?

Answer: 
Use [CGRectIntegral](http://developer.apple.com/IPhone/library/documentation/GraphicsImaging/Reference/CGGeometry/Reference/reference.html#//apple_ref/c/func/CGRectIntegral) to make sure the text fields' frames are based on integer coordinates. You'll get fuzzy antialiasing when things lie on fractional coordinates.
Simply setting the `UITextField` frame height to an even value fixed it for me.
