Swift UIFont IBInspectable - is it possible?

I have a subclass UIView

. In this view, I create instances UIlabel

. Now I want to set the font attributes for these labels in Storyboard. Can you do IBInspectable

for UIFont

?

One of my approaches was this:

@IBInspectable var fontName: UIFont

But that won't work.

To wrap this up: I am trying to get this for UIView

:

Font IBInspectable

I hope someone can help me, thanks! :)

Idea

You can use Int enums to select one of the specific fonts.

More details

xCode 8.2.1, Swift 3

code

enum FontType: Int

import UIKit
enum FontType: Int {
    case Default = 0, Small, Large

    var fount: UIFont {
        switch self {
            case .Default:
                return UIFont.systemFont(ofSize: 17)
            case .Small:
                return UIFont.systemFont(ofSize: 12)
            case .Large:
                return UIFont.systemFont(ofSize: 24)
        }
    }


    static func getFont(rawValue: Int) -> UIFont  {
        if let fontType = FontType(rawValue: rawValue) {
            return fontType.fount
        }
        return FontType.Default.fount
    }
}

      

class View: UIView

import UIKit
@IBDesignable
class View: UIView {

    private var label: UILabel!

    @IBInspectable var textFont:Int = 0

    override func draw(_ rect: CGRect) {
        super.draw(rect)
        label = UILabel(frame: CGRect(x: 20, y: 20, width: 120, height: 40))
        label.text = "Text"
        label.textColor = .black
        label.font = FontType.getFont(rawValue: textFont)
        addSubview(label)
    }

}

desperate times call for desperate measures.



you can define your custom UIView as UITextField or UILabel, so these components already have a font variable. and you can assign self.font to your subviews fonts.

I made this way

fileprivate var _fontSize:CGFloat = 18
    @IBInspectable
    var font:CGFloat
    {
        set
        {
            _fontSize = newValue
            lblPlaceholder.font = UIFont(name: _fontName, size: _fontSize)
        }
        get
        {
            return _fontSize
        }
    }

    fileprivate var _fontName:String = "Helvetica"
    @IBInspectable
    var fontName:String
    {
        set
        {
            _fontName = newValue
            lblPlaceholder.font = UIFont(name: _fontName, size: _fontSize)
        }
        get
        {
            return _fontName
        }
    }
