UITextField padding

Question

Im having trouble creating padding for leftView property of UITextField. The code I have now creates padding for the text which is nice, but I need it for the imageView.

UITextField Subclass method:

• Notice x position of paddingView frame doesn't extend view to the right like expected.

  func setLeftView(imageView: UIImageView, withPadding padding: CGFloat) {
  
  let height = imageView.frame.height
  let width = imageView.frame.width + padding
  
  let paddingView = UIView(frame: CGRect(x: 36, y: 0, width: width, height: height))
  paddingView.addSubview(imageView)
  self.leftView = paddingView
  self.leftViewMode = .always
  }
  

Result:

Answer 1

You need to make changes in your function, just set frame of imageView and set paddingView's X position to 0

func setLeftView(imageView: UIImageView, withPadding padding: CGFloat) {

let height = imageView.frame.height
let width = imageView.frame.width + padding

// Set  x position to 0
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: width, height: height))

/// You need to set frame of imageView so put this line
imageView.frame = CGRect(x: padding, y: 0, width: imageView.frame.width, height: height)

paddingView.addSubview(imageView)
self.leftView = paddingView
self.leftViewMode = .always
}
