UIButton将内容保持在backgroundImage顶部

Question

I have a UIButton and I'm setting a background image on it:

[self.button setBackgroundImage:[UIImage imageNamed:@"button-background"] forState:UIControlStateNormal];

I want the content of the button to stay on top of the background image, and not be affected by it. So when the button content is text, the font color of the text would be unaffected by changing the background image. I'd like it to behave similarly when the button content is an image.

What's the best way to achieve this behavior?

Answer 1

Setting the background of the button does exactly what you're asking. However, make sure your button is in the state you're setting the background image for. Text will appear over this image based on your settings.

forState:UIControlStateNormal (Highlighted, selected, etc)
