如何将 tintColor 应用于 UIImage?

问题描述

我有一个 UIImage 是一个全黑的小符号.UIImage 正在我拥有的自定义 UIButton 子类中设置.是否可以让图像对其应用 tintColor，而不是黑色图像，而是将颜色更改为 tintColor 的任何颜色?

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];
