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

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 button

        UIView.commitAnimations()
        var btnColor = UIButton(type: .Custom)
        btnColor.addTarget(self, action: #selector(self.openEmoji), forControlEvents: .TouchUpInside)
        btnColor.frame = CGRect(x: CGFloat(textField.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
        btnColor.setBackgroundImage(UIImage(named: "send.png"), forState: .Normal)
        textField.addSubview(btnColor)

Please let me know how to give padding from right view for text.

use the rightView property of the UITextField. Basically, there are two properties (this one and leftView accordingly) that allow you to place custom views/controls inside the UITextField. You can control whether those views are shown or not by means of rightViewMode/leftViewMode properties:

textField.rightView = btnColor
textField.rightViewMode = .unlessEditing

for e.g

let button = UIButton(type: .custom)
button.setImage(UIImage(named: "send.png"), for: .normal)
button.imageEdgeInsets = UIEdgeInsetsMake(0, -16, 0, 0)
button.frame = CGRect(x: CGFloat(txt.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
button.addTarget(self, action: #selector(self.refresh), for: .touchUpInside)
textField.rightView = button
textField.rightViewMode = .always

and call the action as 

@IBAction func refresh(_ sender: Any) {
}

You can achieve same as shown below:

@IBOutlet weak var textField: UITextField!

var textFieldBtn: UIButton {
    let button = UIButton(type: .custom)
    button.setImage(UIImage(named: "image.png"), for: .normal)
    button.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, 0)
    button.frame = CGRect(x: CGFloat(textField.frame.size.width - 40), y: CGFloat(5), width: CGFloat(40), height: CGFloat(30))
    button.backgroundColor = UIColor.darkGray
    button.addTarget(self, action: #selector(self.refreshContent), for: .touchUpInside)

    return button
}

func refreshContent() {

    // Add your code here to handle button.
}

Add to textField.

textField.rightView = textFieldBtn
textField.rightViewMode = .always

For Swift4

func setupUI() {
   let imgSearch = UIImageView();
   let imgSearch = UIImage(named: "search");

   // set frame on image before adding it to the uitextfield
   imgSearch.image = imagePassword;
   imgSearch.frame = CGRect(x: txtSearchField.frame.size.width - 40 , y: 5, width: 22, height: 22)
   txtSearchField.rightView = imgSearch
   txtSearchField.rightViewMode = .always
}

Call function like this

 // MARK: View lifecycle
    override func viewDidLoad() {
        super.viewDidLoad()
        self.setupUI()
    }

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
}

Correct answer Swift3+

If you just override the methods, the text may overlap the right view. This code completely solves this problem.

You UITextField subclass:

//...

private func setInsets(forBounds bounds: CGRect) -> CGRect {

    var totalInsets = insets //property in you subClass

    if let leftView = leftView  { totalInsets.left += leftView.frame.origin.x }
    if let rightView = rightView { totalInsets.right += rightView.bounds.size.width }

    return UIEdgeInsetsInsetRect(bounds, totalInsets)
}

override func textRect(forBounds bounds: CGRect) -> CGRect {
    return setInsets(forBounds: bounds)
}

override func placeholderRect(forBounds bounds: CGRect) -> CGRect {
    return setInsets(forBounds: bounds)
}

override func editingRect(forBounds bounds: CGRect) -> CGRect {
    return setInsets(forBounds: bounds)
}

override func rightViewRect(forBounds bounds: CGRect) -> CGRect {

    var rect = super.rightViewRect(forBounds: bounds)
    rect.origin.x -= insets.right

    return rect
}

override func leftViewRect(forBounds bounds: CGRect) -> CGRect {

    var rect = super.leftViewRect(forBounds: bounds)
    rect.origin.x += insets.left

    return rect
}

Create UITextField extension and add below method in it and you can change UIButton code as per your requirement.

func setRightViewIcon(icon: UIImage) {
    let btnView = UIButton(frame: CGRect(x: 0, y: 0, width: ((self.frame.height) * 0.70), height: ((self.frame.height) * 0.70)))
    btnView.setImage(icon, for: .normal)
    btnView.imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 3)
    self.rightViewMode = .always
    self.rightView = btnView
}

you can assign button at right view of textfield 

var btnColor = UIButton(type: .Custom)
            btnColor.addTarget(self, action: #selector(self.openEmoji), forControlEvents: .TouchUpInside)
            btnColor.frame = CGRect(x: CGFloat(textField.frame.size.width - 25), y: CGFloat(5), width: CGFloat(25), height: CGFloat(25))
            btnColor.setBackgroundImage(UIImage(named: "send.png"), forState: .Normal)
            textField.rightView = btnColor
