Add a button on right view of UItextfield in such way that, text should not overlap the button

Question

I can add a button to a textfield on the right hand side of the UITextField using the right view however, the text overlaps on the button. Below is the code for right view butto

Answer 1

internal var btnDropDown: UIButton {
    let size: CGFloat = 25.0
    let button = UIButton(type: .custom)
    button.setImage(#imageLiteral(resourceName: "DropDownImage"), for: .normal)
    button.imageEdgeInsets = UIEdgeInsetsMake(0, -(size/2.0), 0, 0)
    button.frame = CGRect(x: self.frame.size.width - size, y: 0.0, width: size, height: size)
    return button
}

And I used it like this:

override func awakeFromNib() {
    super.awakeFromNib()   
    textField.rightView = self.btnDropDown
    textField.rightViewMode = .always
}
