Customize Color, background from UISearchBar in Swift

// as UISearchBar extension
extension UISearchBar {
  func changeSearchBarColor(color : UIColor) {
    for subView in self.subviews {
      for subSubView in subView.subviews {
        if subSubView.conformsToProtocol(UITextInputTraits.self) {
          let textField = subSubView as UITextField
          textField.backgroundColor = color
          break
        }
      }
    }
  }
}

not working :(

let searchBar = UISearchBar(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
//ColorImage is an image with background color
searchBar.setSearchFieldBackgroundImage(UIImage(named: "ColorImage"), for: UIControlState.normal)

this code work on iOS 10, Swift 3.0

// as UISearchBar extension
extension UISearchBar {
    func changeSearchBarColor(color : UIColor) {
        for subView in self.subviews {
            for subSubView in subView.subviews {
                
                if let _ = subSubView as? UITextInputTraits {
                    let textField = subSubView as! UITextField
                    textField.backgroundColor = color
                    break
                }
                
            }
        }
    }
}

Updated original code for Swift 3.0

The solution with subviews doesn't work for me. So here's my extension:

extension UISearchBar {
    func changeSearchBarColor(color: UIColor) {
        UIGraphicsBeginImageContext(self.frame.size)
        color.setFill()
        UIBezierPath(rect: self.frame).fill()
        let bgImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        
        self.setSearchFieldBackgroundImage(bgImage, for: .normal)
    }
}

public extension UISearchBar {
  public func setStyleColor(_ color: UIColor) {
    tintColor = color
    guard let tf = (value(forKey: "searchField") as? UITextField) else { return }
    tf.textColor = color
    if let glassIconView = tf.leftView as? UIImageView, let img = glassIconView.image {
      let newImg = img.blendedByColor(color)
      glassIconView.image = newImg
    }
    if let clearButton = tf.value(forKey: "clearButton") as? UIButton {
      clearButton.setImage(clearButton.imageView?.image?.withRenderingMode(.alwaysTemplate), for: .normal)
      clearButton.tintColor = color
    }
  }
}

extension UIImage {
  
  public func blendedByColor(_ color: UIColor) -> UIImage {
    let scale = UIScreen.main.scale
    if scale > 1 {
      UIGraphicsBeginImageContextWithOptions(size, false, scale)
    } else {
      UIGraphicsBeginImageContext(size)
    }
    color.setFill()
    let bounds = CGRect(x: 0, y: 0, width: size.width, height: size.height)
    UIRectFill(bounds)
    draw(in: bounds, blendMode: .destinationIn, alpha: 1)
    let blendedImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return blendedImage!
  }
}

works perfectly

@shev-vadim-net Thanks!

extension UISearchBar {
    func changeSearchBarColor(fieldColor: UIColor, backColor: UIColor, borderColor: UIColor?) {
        UIGraphicsBeginImageContext(bounds.size)
        backColor.setFill()
        UIBezierPath(rect: bounds).fill()
        setBackgroundImage(UIGraphicsGetImageFromCurrentImageContext()!, for: UIBarPosition.any, barMetrics: .default)
        
        let newBounds = bounds.insetBy(dx: 0, dy: 8)
        fieldColor.setFill()
        let path = UIBezierPath(roundedRect: newBounds, cornerRadius: newBounds.height / 2)
        
        if let borderColor = borderColor {
            borderColor.setStroke()
            path.lineWidth = 1 / UIScreen.main.scale
            path.stroke()
        }
        
        path.fill()
        setSearchFieldBackgroundImage(UIGraphicsGetImageFromCurrentImageContext()!, for: UIControlState.normal)
        
        UIGraphicsEndImageContext()
    }
}

extension UISearchBar {
    
    var textField: UITextField? {
        
        return subviews.map { $0.subviews.first(where: { $0 is UITextInputTraits}) as? UITextField }
            .compactMap { $0 }
            .first
    }
}

//Usage:
let bar = UISearchBar()
bar.textField?.backgroundColor = .red

extension UISearchBar { func changeSearchBarColor(color: UIColor) { UIGraphicsBeginImageContext(self.frame.size) color.setFill() UIBezierPath(rect: self.frame).fill() let bgImage = UIGraphicsGetImageFromCurrentImageContext()! UIGraphicsEndImageContext() self.setSearchFieldBackgroundImage(bgImage, for: .normal) } }
This works for me but the color goes outside the textfield bounds how can I make it stay within the textfield.
PS: I have set clipToBounds to be true and everything I could think of and my searchbar is minimal

extension UISearchBar { func changeSearchBarColor(color: UIColor) { UIGraphicsBeginImageContext(self.frame.size) color.setFill() UIBezierPath(rect: self.frame).fill() let bgImage = UIGraphicsGetImageFromCurrentImageContext()! UIGraphicsEndImageContext() self.setSearchFieldBackgroundImage(bgImage, for: .normal) } }

did you find a solution?

@hell4opt Yeah I did for the size I had to do this let size = CGSize(width: self.frame.size.width, height: 45) you have to play with the height till you get what you want.

This is my full code for anyone having the same issue
extension UISearchBar {
  func changeSearchBarColor(color: UIColor, size: CGSize) {
        UIGraphicsBeginImageContext(self.frame.size)
        color.setFill()
        UIBezierPath(rect: self.frame).fill()
        let bgImage = UIGraphicsGetImageFromCurrentImageContext()!
        UIGraphicsEndImageContext()
        self.setSearchFieldBackgroundImage(bgImage, for: .normal)
    }
}

Then you call it like so yourSearchBar.changeSearchBarColor(color: yellow, size: CGSize(width: yourSearchBar.frame.size.width, height: 45))

thanks!) but the height does not work (and the corner radius is not enough)
