Ios 如何给按钮上色，然后当你点击它时，它就不会'；你不能改变颜色吗？

我有一个黑色图标，我用它来形象按钮。按程序我把这个按钮染成灰色。当屏幕显示时，按钮为灰色，但一旦我点击按钮，它将再次变为黑色

这是我为按钮着色的方式：

addQuantityButton.imageView?.image = addQuantityButton.imageView?.image?.withRenderingMode(.alwaysTemplate)
addQuantityButton.imageView?.tintColor = .gray

谢谢

试试这个：

setImage(image.withRenderingMode(.alwaysTemplate), for: .highlighted)

试试这个：

setImage(image.withRenderingMode(.alwaysTemplate), for: .highlighted)
