My code:
self.commentTextViewBorder.image = [[UIImage imageNamed:@"border_comment_field"]
resizableImageWithCapInsets:UIEdgeInsetsMake(11, 11, 11, 11)];
I found it did not user @2x image file to make resiable. Is it any problem?
Put your image_name.png
& image_name@2x.png
at your main bundle folder, and just use
[UIImage imageNamed:@"image_name.png"];
is fine. The correct one will be used automatically depend on the devices w/ or w/o retina display.
