How to get the name of a UIColor?

问题

I have an array of UIColors like

[UIColor blueColor];

is it possible to get the name "blue" from that UIColor, to display it in a string?

回答1:

There's nothing built in to UIKit, but Erica Sadun's uicolor-utilities library adds similar functionality.

回答2:

You can get RGB and Alpha of the UIColor, if you want.

回答3:

A list of color names can be obtained using runtime. See my question: How to get all Color methods of UIColor?

You can also use string methods to convert 'xxxColor' to 'xxx' if needed.
