在 Objective-C 中分配 UIColor 标准颜色

Question

我正在尝试将 FSCalendarStandardSeparatorColor UIColor 变量的颜色从不透明度为 60% 的 lightGray 更改为 UIColor.separator。我想这样做，因为这个库是在明/暗模式功能之前创建的，我想通过使用 UIKit 标准颜色来允许这一点。

#define FSCalendarStandardSeparatorColor [[UIColor lightGrayColor] colorWithAlphaComponent：0.60]

当我将其更改为

#define FSCalendarStandardSeparatorColor [UIColor 分隔符]

我收到错误

弧语义问题 选择器"分隔符"没有已知的类方法

Answer 1

它应该在Objective-C中[UIColor separatorColor]。

另外，请注意，它仅从iOS 13开始可用。所以你需要相应地保护。
