问题描述
我在UIButton backgroundImage属性中使用的图像有点奇怪。正如你从图片中看到的那样，前景图像（在UIImageView中）更清晰，而背景图像则模糊不清 - 这是UIButton上的图像。
I have a bit of an odd problem with an image I'm using in a UIButton backgroundImage property. As you can see from the picture, the foreground image (in an UIImageView) is much clearer, whereas the background one, is blurred and not as good looking - this is a image on a UIButton.
想法？要尝试的事情？任何想法，将不胜感激。我在IB中做这一切。
Thoughts? Things to try? Any ideas would be appreciated. I'm doing this all in IB.
推荐答案
