检测 UIColor 是否是用 colorWithPatternImage 创建的 [英] Detecting if UIColor was created with colorWithPatternImage

问题描述

我有一个传递给我的 UIColor.我需要检测它是纯色(例如用 colorWithRed:green:blue:alpha: 创建)还是用​​ colorWithPatternImage 创建的颜色.

I have a UIColor that is passed into me. I need to detect if it is a plain color (e.g. created with colorWithRed:green:blue:alpha:) or if it is a color that was created with colorWithPatternImage.

如何判断 UIColor 是什么颜色，简单的颜色还是其他颜色?

How can I tell what kind of color a UIColor is, simple color or otherwise?

推荐答案

您应该能够使用带有 CGColor 属性的 CGColorGetPattern 函数，并检查 >NULL.

You should be able to use the CGColorGetPattern function with the CGColor property, and check for NULL.

if( CGColorGetPattern( myColor.CGColor ) != NULL ) {}
