Label under image in UIButton

Question

I\'m trying to create a button which has some text beneath the icon (sorta like the app buttons) however it seems to be quite difficult to achieve. Any ideas how can I go ab

Use this two methods:

func titleRect(forContentRect contentRect: CGRect) -> CGRect
func imageRect(forContentRect contentRect: CGRect) -> CGRect

Example:

class VerticalButton: UIButton {

  override func titleRect(forContentRect contentRect: CGRect) -> CGRect {
    let titleRect = super.titleRect(forContentRect: contentRect)
    let imageRect = super.imageRect(forContentRect: contentRect)

    return CGRect(x: 0,
                  y: contentRect.height - (contentRect.height - padding - imageRect.size.height - titleRect.size.height) / 2 - titleRect.size.height,
                  width: contentRect.width,
                  height: titleRect.height)
  }

  override func imageRect(forContentRect contentRect: CGRect) -> CGRect {
    let imageRect = super.imageRect(forContentRect: contentRect)
    let titleRect = self.titleRect(forContentRect: contentRect)

    return CGRect(x: contentRect.width/2.0 - imageRect.width/2.0,
                  y: (contentRect.height - padding - imageRect.size.height - titleRect.size.height) / 2,
                  width: imageRect.width,
                  height: imageRect.height)
  }

  private let padding: CGFloat
  init(padding: CGFloat) {
    self.padding = padding

    super.init(frame: .zero)
    self.titleLabel?.textAlignment = .center
  }

  required init?(coder aDecoder: NSCoder) { fatalError() }
}

extension UIButton {

  static func vertical(padding: CGFloat) -> UIButton {
    return VerticalButton(padding: padding)
  }
}

And you can use:

let myButton = UIButton.vertical(padding: 6)
