如何将tintColor应用于UIImage？ [英] How to apply a tintColor to a UIImage?

问题描述

我有一个 UIImage 这是一个全黑的小符号。 UIImage 是在我拥有的自定义 UIButton 子类中设置的。是否可以让图像应用 tintColor ，而不是黑色图像，它将颜色更改为 tintColor 是吗？

I have a UIImage that is a small symbol that is all black. The UIImage is getting set in a custom UIButton subclass I have. Is it possible to have the image to apply the tintColor to it, so instead of the black image it changes colors to whatever the tintColor is?

我只是想避免创建新资产。

I'm just trying to avoid creating new assets.

// here I want defaultImageName (that is black) to use the tintColor (that is white)
[self setImage:[UIImage imageNamed:defaultImageName] forState:UIControlStateNormal];
