如何创建类似于IBInspectable属性的段控件?

问题描述

我想创建自定义控件(如段控件)，但是我不明白如何创建这种Segment IBInspectable属性.我的意思是根据Segments，它的元素在增加.据我所知，@IBInspectable中不支持数组.

推荐答案

您还不能创建该类型的@IBInspectable(至今)，但是...

You can't create that type of @IBInspectable (yet), but...

您可以将String变量定义为@IBInspectable var，并向其中添加多行.然后使用didSet方法将字符串拆分成一个供内部使用的数组(例如)...

You can define a String variable as an @IBInspectable var, and add multiple lines to it. Then have a didSet method split the string into an array which you use internally (for example)...

遵循以下原则:

private var internalTextArray: [String]?

@IBInspectable var segments: String = "" {
    didSet {
        internalTextArray = segments.components(separatedBy: "\n")
        // do something with the split-up lines of text
    }
}
