How to change the tint color of the clear button on a UITextField

I have an auto-generated clear button on my UITextfield, with the default blue tint color. I cannot change the tint color to white. I have tried modifying the storyboard and code without success, and I do not want to use a custom image.

How can I change the default clear button tint color without using a custom image?


Answer Source

Here you go!

A TintTextField.

Using no custom image, or added buttons etc.

enter image description here

class TintTextField: UITextField {

  var tintedClearImage: UIImage?

  required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

  override init(frame: CGRect) {
    super.init(frame: frame)

  func setupTintColor() {
    clearButtonMode = UITextFieldViewMode.WhileEditing
    borderStyle = UITextBorderStyle.RoundedRect
    layer.cornerRadius = 8.0
    layer.masksToBounds = true
    layer.borderColor = tintColor.CGColor
    layer.borderWidth = 1.5
    backgroundColor = UIColor.clearColor()
    textColor = tintColor

  override func layoutSubviews() {

  private func tintClearImage() {
    for view in subviews as! [UIView] {
      if view is UIButton {
        let button = view as! UIButton
        if let uiImage = button.imageForState(.Highlighted) {
          if tintedClearImage == nil {
            tintedClearImage = tintImage(uiImage, tintColor)
          button.setImage(tintedClearImage, forState: .Normal)
          button.setImage(tintedClearImage, forState: .Highlighted)

func tintImage(image: UIImage, color: UIColor) -> UIImage {
  let size = image.size

  UIGraphicsBeginImageContextWithOptions(size, false, image.scale)
  let context = UIGraphicsGetCurrentContext()
  image.drawAtPoint(CGPointZero, blendMode: CGBlendMode.Normal, alpha: 1.0)

  CGContextSetFillColorWithColor(context, color.CGColor)
  CGContextSetBlendMode(context, CGBlendMode.SourceIn)
  CGContextSetAlpha(context, 1.0)

  let rect = CGRectMake(
  CGContextFillRect(UIGraphicsGetCurrentContext(), rect)
  let tintedImage = UIGraphicsGetImageFromCurrentImageContext()

  return tintedImage
