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

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

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
}

Answer 4

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

Answer 5

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
}

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()
    }
