如何调整UIButton的imageSize？ [英] How to adjust an UIButton's imageSize?

问题描述

如何调整UIButton的图像大小？我正在设置这样的图像：

How can I adjust the image size of the UIButton? I am setting the image like this:

 [myLikesButton setImage:[UIImage imageNamed:@"icon-heart.png"] forState:UIControlStateNormal];

然而，这会将图像填满整个按钮，如何缩小图像？

However this fills up the image to the full button, how do I make the image smaller?

推荐答案

如果我理解你正在尝试做什么，你需要使用按钮图像边缘插图。类似于：

If I understand correctly what you're trying to do, you need to play with the buttons image edge inset. Something like:

myLikesButton.imageEdgeInsets = UIEdgeInsetsMake(top, left, bottom, right);
