how to make button round with image background in IPhone?
提问by user4951
I have a round button, but i will make it have a backgroud with image.
我有一个圆形按钮，但我会让它有一个带有图像的背景。
but when i do it, by setting the (what) property to an image, the button becomes rectangle because the image is a rectangle. How do I keep the button round?
但是当我这样做时，通过将 (what) 属性设置为图像，按钮变为矩形，因为图像是矩形。如何让按钮保持圆形？

Best solution I have found especially for UITableCell. I put the code in awakeFromNib and worked right off the bat.
我为 UITableCell 找到的最佳解决方案。我将代码放在awakeFromNib 中并立即开始工作。
