Is it possible to rotate an IBDesignable UIButton using Swift?

swift

Solution

You should create `CustomButton` inherited from `UIButton`

import UIKit

@IBDesignable
class CustomButton: UIButton {

    @IBInspectable var rotation: Double = 0 {
        didSet {
            rotateButton(rotation: rotation)
        }
    }

    func rotateButton(rotation: Double)  {
        self.transform = CGAffineTransform(rotationAngle: CGFloat(.pi/2 + rotation))
    }
}

You will get following output,

Problem

How to make an IBDesignable component that has an angle: CGFloat property that rotates the view ``` import UIKit @IBDesignable class MyB: UIButton { @IBInspectable var angle: CGFloat = 0 { didSet { //What to put here? } } override init(frame: CGRect) { super.init(frame: frame) // Initialization code } required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) } } ``` I tried ``` self.transform = CGAffineTransformMakeRotation(angle) ``` but it doesn't work
