How can I prevent a border on a TTThumbView in Three20

I'm using TTThumbView to show images but 开发者_如何学Pythonbefore the image is loaded I can see a border on the TTThumbView and then once the image is loaded I believe I'm getting a border showing through the edge of my image. Can anyone point me in the direction to prevent this please - I'm not sure if it's something I should set in styleForState. I have tried the Three20 forum but have not had any responses yet

Have a look at your stylesheets thumbView: implementation. You would want to remove the TTSolidBorderStyle.
