How to create segment control like IBInspectable properties?

问题

I want to create custom control like segment control But i'm not able to understand how to create this kind of Segment IBInspectable properties. i mean it's elements increasing according to Segments. as i know there is no support of array in @IBInspectable.

回答1:

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

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)...

Something along these lines:

private var internalTextArray: [String]?

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

回答2:

@IBInspectable properties is backed by user-defined runtime attribute which is not support Segment data type yet. So I believe that Storyboard does not support the feature you want.
