I am trying to create an underlined text field with placeholder text, I got the following extension to help out.
extension UITextField {
func setBottomLine(borderColor: UIColor) {
borderStyle = .none
backgroundColor = .clear
let borderLine = CALayer()
borderLine.frame = CGRect(x: 0, y: frame.height - 2, width: frame.width, height: 2)
layer.addSublayer(borderLine)
}
I call this extension in layout subviews of my view controller, and whenever I assign placeholder text nothing shows up. I am very confused on what the problem is. Thanks!
extension UITextField {
func setUnderLine() {
let border = CALayer()
let width = CGFloat(0.5)
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width - 10, height: self.frame.size.height)
border.borderWidth = width
self.layer.addSublayer(border)
self.layer.masksToBounds = true
}
}
override func viewDidLoad() {
super.viewDidLoad()
mytextField.setUnderLine()
}
Check this out.
import UIKit
class ViewController: UIViewController {
#IBOutlet weak var yourTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
yourTextField.textFieldUnderscoreAndPlaceholder()
}
}
extension UITextField {
//MARK: Text underscore with placeholder
func textFieldUnderscoreAndPlaceholder() {
//Underscore
let textFieldUnderscore = CALayer()
textFieldUnderscore.frame = CGRect(x: 0.0, y: frame.height - 1, width: frame.width, height: 1.0)
bounds = bounds.insetBy(dx: 0, dy: -2)
textFieldUnderscore.backgroundColor = UIColor(red: 0, green: 0, blue: 0, alpha: 1).cgColor
layer.addSublayer(textFieldUnderscore)
//Placeholder
placeholder = "Type some text here..."
}
}
I am new to swift. Your help will be really appreciated.
I have two textfields in my application. How would I create same UI as given in the pic below.
I want to create textfields with only one below border as given in the screenshot.

#IBOutlet var textField: UITextField! {
didSet {
let border = CALayer()
let width: CGFloat = 1 // this manipulates the border's width
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: textField.frame.size.height - width,
width: textField.frame.size.width, height: textField.frame.size.height)
border.borderWidth = width
textField.layer.addSublayer(border)
textField.layer.masksToBounds = true
}
}
Create a subclass of UITextField so you can reuse this component across multiple views without have to re implement the drawing code. Expose various properties via #IBDesignable and #IBInspectable and you can have control over color and thickness in the story board. Also - implement a "redraw" on by overriding layoutSubviews so the border will adjust if you are using auto layout and there is an orientation or perhaps constraint based animation. That all said - effectively your subclass could look like this:
import UIKit
class Field: UITextField {
private let border = CAShapeLayer()
#IBInspectable var color: UIColor = UIColor.blue {
didSet {
border.strokeColor = color.cgColor
}
}
#IBInspectable var thickness: CGFloat = 1.0 {
didSet {
border.lineWidth = thickness
}
}
override func draw(_ rect: CGRect) {
self.borderStyle = .none
let from = CGPoint(x: 0, y: rect.height)
let here = CGPoint(x: rect.width, y: rect.height)
let path = borderPath(start: from, end: here).cgPath
border.path = path
border.strokeColor = color.cgColor
border.lineWidth = thickness
border.fillColor = nil
layer.addSublayer(border)
}
override func layoutSubviews() {
super.layoutSubviews()
let from = CGPoint(x: 0, y: bounds.height)
let here = CGPoint(x: bounds.width, y: bounds.height)
border.path = borderPath(start: from, end: here).cgPath
}
private func borderPath(start: CGPoint, end: CGPoint) -> UIBezierPath {
let path = UIBezierPath()
path.move(to: start)
path.addLine(to: end)
return path
}
}
Then when you add a text field view to your story board - update the class in the Identity Inspector to use this subclass, Field - and then in the attributes inspector, you can set color and thickness.
Add border at Bottom in UITextField call below function:
func setTextFieldBorder(_ dimension: CGRect) -> CALayer {
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: dimension.size.height - width, width: dimension.size.width, height: dimension.size.height)
border.borderWidth = width
return border
}
How to set UITextField border in textField below sample code for that:
txtDemo.layer.addSublayer(setTextFieldBorder(txtDemo.frame))
txtDemo.layer.masksToBounds = true
Where txtDemo is IBOutlet of UITextField.
I have a UITextField that must have a bottom border. Since autolayout use my code is this:
override func viewDidLayoutSubviews() {
let border = CALayer()
let width = CGFloat(0.5)
border.borderColor = UIColor.darkGray.withAlphaComponent(0.3).cgColor
border.frame = CGRect(x: 0, y: txtUsername.frame.size.height - width, width: txtUsername.frame.size.width, height: txtUsername.frame.size.height)
border.borderWidth = width
txtUsername.layer.addSublayer(border)
txtUsername.layer.masksToBounds = true
}
This, however, excludes the fact that when I touch the UITextField, this should create me a shadow. the code is this:
//ombra txtField
self.view.addSubview(txtUsername)
txtUsername.layer.shadowOffset = CGSize(width: 5, height: 10)
txtUsername.layer.shadowOpacity = 0.3
txtUsername.layer.shadowRadius = 10
txtUsername.layer.masksToBounds = false;
txtUsername.clipsToBounds = false
the one excludes the other. how do I fix?`
You can use CAShapeLayerShadow
func border(){
let border = CALayer()
let width = CGFloat(0.5)
border.borderColor = UIColor.darkGray.withAlphaComponent(1).cgColor
border.frame = CGRect(x: 0, y: CustomerTextBox.frame.size.height - width, width: CustomerTextBox.frame.size.width, height: CustomerTextBox.frame.size.height)
border.borderWidth = width
CustomerTextBox.layer.addSublayer(border)
CustomerTextBox.layer.masksToBounds = true
}
func shadow(){
let Shape = CAShapeLayer()
let myPath = UIBezierPath(ovalIn: CustomerTextBox.frame)
Shape.shadowPath = myPath.cgPath
Shape.shadowColor = UIColor.lightGray.cgColor
Shape.shadowOffset = CGSize(width: 5, height: 3)
Shape.shadowRadius = 5
Shape.shadowOpacity = 0.8
view.layer.insertSublayer(Shape, at: 0)
}
I would like to move the code to customize UIButtons out of my viewcontroller classes as a best practice. The code I have below is to add a white border to UIButtons and I would like to easily call it on buttons throughout my project.
//White Border
let passwordBorder = CALayer()
let width = CGFloat(5.0)
passwordBorder.borderColor = UIColor.whiteColor().CGColor
passwordBorder.frame = CGRect(x: 0, y: 0, width: passwordField.frame.size.width, height: passwordField.frame.size.height)
passwordBorder.borderWidth = width
passwordField.layer.addSublayer(passwordBorder)
passwordField.layer.masksToBounds = true
How would I put this code into a helper function so I could call it easily?
I am new to coding and am having trouble with helper functions on anything UI. Thanks!
Take a look at Swift's Extensions. You could pretty easily do something like
extension UIButton {
func setPasswordBorderColor(borderColor: UIColor) {
//White Border
let passwordBorder = CALayer()
let width = CGFloat(5.0)
passwordBorder.borderColor = borderColor.CGColor
passwordBorder.frame = CGRect(x: 0, y: 0, width: self.frame.size.width, height: self.frame.size.height)
passwordBorder.borderWidth = width
self.layer.addSublayer(passwordBorder)
self.layer.masksToBounds = true
}
}
import UIKit
//
#IBDesignable
class CustomBorderButton: UIButton {
#IBInspectable var cornerRadius: CGFloat = 0 {
didSet {
layer.cornerRadius = cornerRadius
layer.masksToBounds = cornerRadius > 0
}
}
#IBInspectable var borderWidth: CGFloat = 0 {
didSet {
layer.borderWidth = borderWidth
}
}
#IBInspectable var borderColor: UIColor? {
didSet {
layer.borderColor = borderColor?.CGColor
}
}
}
Without Code you can configure your button
Select Your button then Select Identity Inspector then add
"User Defined Runtime Attribute".See screen Shot for more details
Add CALayer+XibConfiguration.h & CALayer+XibConfiguration.m in your Project
for CALayer+XibConfiguration open this link & download CALayer+XibConfiguration
There are several ways by which you can achieve this like using category, subclassing UIButton, or create a function in a class (may be base class inherited by all other classes.), etc.
By using function you ca do
func cutomizeButton(frame : CGRect, title : String) -> UIButton {
let button : UIButton = UIButton(type: .Custom)
button.frame = frame
button.layer.borderWidth = 5.0
button.layer.borderColor = UIColor.whiteColor().CGColor;
button.layer.masksToBounds = true
button.titleLabel?.text = title;
//do other stuff
return button;
}
In helper class make method like
func customiseButton(button:UIButton){
//White Border
let passwordBorder = CALayer()
let width = CGFloat(5.0)
passwordBorder.borderColor = UIColor.whiteColor().CGColor
passwordBorder.frame = CGRect(x: 0, y: 0, width: button.frame.size.width, height: button.frame.size.height)
passwordBorder.borderWidth = width
button.layer.addSublayer(passwordBorder)
button.layer.masksToBounds = true
}
and in ViewController call this method as
HelperClass().customiseButton(passwordField)
You can try with this Extension for round button:
extension UIButton{
func roundCorners(corners:UIRectCorner, radius: CGFloat){
let borderLayer = CAShapeLayer()
borderLayer.frame = self.layer.bounds
borderLayer.strokeColor = UIColor.green.cgColor
borderLayer.fillColor = UIColor.clear.cgColor
borderLayer.lineWidth = 10.5
let path = UIBezierPath(roundedRect: self.bounds,
byRoundingCorners: corners,
cornerRadii: CGSize(width: radius, height: radius))
borderLayer.path = path.cgPath
self.layer.addSublayer(borderLayer)
}
}
I want to show only bottom border and hide the other sides.
Output I see: As you can see I see the top, left and right borders also and they are black in color, I want to remove them. Only need the bottom white thick 2.0 border.
Code I am using (source):
var border = CALayer()
var width = CGFloat(2.0)
border.borderColor = UIColor.whiteColor().CGColor
border.frame = CGRect(x: 0, y: tv_username.frame.size.height - width, width: tv_username.frame.size.width, height: tv_username.frame.size.height)
border.borderWidth = width
tv_username.backgroundColor = UIColor.clearColor()
tv_username.layer.addSublayer(border)
tv_username.layer.masksToBounds = true
tv_username.textColor = UIColor.whiteColor()
Try to do by this way, with Swift 5.1:
var bottomLine = CALayer()
bottomLine.frame = CGRect(x: 0.0, y: myTextField.frame.height - 1, width: myTextField.frame.width, height: 1.0)
bottomLine.backgroundColor = UIColor.white.cgColor
myTextField.borderStyle = UITextField.BorderStyle.none
myTextField.layer.addSublayer(bottomLine)
You have to set the borderStyle property to None
If you are using the autolayout then set perfect constraint else bottomline will not appear.
Hope it helps.
Thought from #Ashish's answer, used same approach long ago in Objective-C but implementing extension will be more useful.
extension UITextField {
func addBottomBorder(){
let bottomLine = CALayer()
bottomLine.frame = CGRect(x: 0, y: self.frame.size.height - 1, width: self.frame.size.width, height: 1)
bottomLine.backgroundColor = UIColor.white.cgColor
borderStyle = .none
layer.addSublayer(bottomLine)
}
}
In your controller:
self.textField.addBottomBorder()
Can add further parameters to your method, like adding border height, color.

I liked the answer that included masksToBounds by Mina Fawzy...
I ran into this issue where I was trying to style a bottom border of a UITextField, and the comments using a CGRect worked for me, however, I ran into issues when using different screen sizes, or if I changed the orientation to landscape view from the portrait.
ie. My Xcode Main.storyboard was designed with iPhone XS Max, with a UITextField constrained to be 20 points from the left/right of the screen. In my viewDidLoad() I stylized the UITextField (textfield) using the CGRect approach, making the width of the rectangle equal to textfield.frame.width.
When testing on the iPhone XS Max, everything worked perfectly, BUT, when I tested on iPhone 7 (smaller screen width) the CGRect was grabbing the width of the iPhone XS Max during the viewDidLoad(), causing the rectangle (bottom line) to be too wide, and the right edge went off the screen. Similarly, when I tested on iPad screens, the bottom line was way too short. And also, on any device, rotating to landscape view did not re-calculate the size of the rectangle needed for the bottom line.
The best solution I found was to set the width of the CGRect to larger than the longest iPad dimension (I randomly chose 2000) and THEN added textfield.layer.masksToBounds = true. This worked perfectly because now the line is plenty long from the beginning, does not need to be re-calculated ever, and is clipped to the correct width of the UITextField no matter what screen size or orientation.
Thanks Mina, and hope this helps others with the same issue!
Objective C
[txt.layer setBackgroundColor: [[UIColor whiteColor] CGColor]];
[txt.layer setBorderColor: [[UIColor grayColor] CGColor]];
[txt.layer setBorderWidth: 0.0];
[txt.layer setCornerRadius:12.0f];
[txt.layer setMasksToBounds:NO];
[txt.layer setShadowRadius:2.0f];
txt.layer.shadowColor = [[UIColor blackColor] CGColor];
txt.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
txt.layer.shadowOpacity = 1.0f;
txt.layer.shadowRadius = 1.0f;
Swift
textField.layer.backgroundColor = UIColor.whiteColor().CGColor
textField.layer.borderColor = UIColor.grayColor().CGColor
textField.layer.borderWidth = 0.0
textField.layer.cornerRadius = 5
textField.layer.masksToBounds = false
textField.layer.shadowRadius = 2.0
textField.layer.shadowColor = UIColor.blackColor().CGColor
textField.layer.shadowOffset = CGSizeMake(1.0, 1.0)
textField.layer.shadowOpacity = 1.0
textField.layer.shadowRadius = 1.0
I have tried all this answer but no one worked for me except this one
let borderWidth:CGFloat = 2.0 // what ever border width do you prefer
let bottomLine = CALayer()
bottomLine.frame = CGRectMake(0.0, Et_textfield.height - borderWidth, Et_textfield.width, Et_textfield.height )
bottomLine.backgroundColor = UIColor.blueColor().CGColor
bottomLine
Et_textfield.layer.addSublayer(bottomLine)
Et_textfield.layer.masksToBounds = true // the most important line of code
Swift 3:
Just subclass your UITextField
class BottomBorderTF: UITextField {
var bottomBorder = UIView()
override func awakeFromNib() {
//MARK: Setup Bottom-Border
self.translatesAutoresizingMaskIntoConstraints = false
bottomBorder = UIView.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
bottomBorder.backgroundColor = UIColor.orange
bottomBorder.translatesAutoresizingMaskIntoConstraints = false
addSubview(bottomBorder)
//Mark: Setup Anchors
bottomBorder.bottomAnchor.constraint(equalTo: bottomAnchor).isActive = true
bottomBorder.leftAnchor.constraint(equalTo: leftAnchor).isActive = true
bottomBorder.rightAnchor.constraint(equalTo: rightAnchor).isActive = true
bottomBorder.heightAnchor.constraint(equalToConstant: 1).isActive = true // Set Border-Strength
}
}
Solution which using CALayer is not good because when device is rotated the underline doesn't change width.
class UnderlinedTextField: UITextField {
override func awakeFromNib() {
super.awakeFromNib()
let bottomLine = CALayer()
bottomLine.frame = CGRect(x: 0, y: self.frame.size.height, width: UIScreen.main.bounds.width, height: 1)
bottomLine.bounds = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: self.frame.size.height)
bottomLine.backgroundColor = UIColor.black.cgColor
borderStyle = .none
layer.addSublayer(bottomLine)
layer.masksToBounds = true
}
}
The best solution is to use UIView.
class UnderlinedTextField: UITextField {
private let defaultUnderlineColor = UIColor.black
private let bottomLine = UIView()
override func awakeFromNib() {
super.awakeFromNib()
borderStyle = .none
bottomLine.translatesAutoresizingMaskIntoConstraints = false
bottomLine.backgroundColor = defaultUnderlineColor
self.addSubview(bottomLine)
bottomLine.topAnchor.constraint(equalTo: self.bottomAnchor, constant: 1).isActive = true
bottomLine.leadingAnchor.constraint(equalTo: self.leadingAnchor).isActive = true
bottomLine.trailingAnchor.constraint(equalTo: self.trailingAnchor).isActive = true
bottomLine.heightAnchor.constraint(equalToConstant: 1).isActive = true
}
public func setUnderlineColor(color: UIColor = .red) {
bottomLine.backgroundColor = color
}
public func setDefaultUnderlineColor() {
bottomLine.backgroundColor = defaultUnderlineColor
}
}
First set borderStyle property to .none.
Also, don't forget that the best time to call this method in the viewDidAppear(_:) method.
To make it handy, you can use an extension:
extension UIView {
func addBottomBorderWithColor(color: UIColor, width: CGFloat) {
let border = CALayer()
border.backgroundColor = color.cgColor
border.frame = CGRect(x: 0, y: self.frame.size.height - width,
width: self.frame.size.width, height: width)
self.layer.addSublayer(border)
}
}
Call it like:
textfield.addBottomBorderWithColor(color: UIColor.lightGray, width: 0.5)
Using extension and Swift 5.3
extension UITextField {
internal func addBottomBorder(height: CGFloat = 1.0, color: UIColor = .black) {
let borderView = UIView()
borderView.backgroundColor = color
borderView.translatesAutoresizingMaskIntoConstraints = false
addSubview(borderView)
NSLayoutConstraint.activate(
[
borderView.leadingAnchor.constraint(equalTo: leadingAnchor),
borderView.trailingAnchor.constraint(equalTo: trailingAnchor),
borderView.bottomAnchor.constraint(equalTo: bottomAnchor),
borderView.heightAnchor.constraint(equalToConstant: height)
]
)
}
}
For those looking for a solution that works for Autolayout, IBInspectable, and the Storyboard, subclass UITextField into your custom textfield class and add these:
func setUnderline() {
for sub in self.subviews {
sub.removeFromSuperview()
}
if underlineStyle == true {
var bottomBorder = UIView()
bottomBorder = UIView.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
bottomBorder.backgroundColor = borderColor //YOUR UNDERLINE COLOR HERE
bottomBorder.translatesAutoresizingMaskIntoConstraints = false
self.addSubview(bottomBorder)
bottomBorder.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
bottomBorder.leftAnchor.constraint(equalTo: self.leftAnchor).isActive = true
bottomBorder.rightAnchor.constraint(equalTo: self.rightAnchor).isActive = true
bottomBorder.heightAnchor.constraint(equalToConstant: underlineHeight).isActive = true
layoutIfNeeded()
}
}
#IBInspectable var underlineStyle: Bool = false {
didSet {
setUnderline()
}
}
#IBInspectable var underlineHeight: CGFloat = 0 {
didSet {
setUnderline()
}
}
Swift 5.
extension UITextField {
let bottomLine = UIView()
bottomLine.backgroundColor = .black
borderStyle = .none
self.addSubview(bottomLine)
NSLayoutConstraint.activate([
bottomLine.topAnchor.constraint(equalTo: bottomAnchor + 10),
bottomLine.leadingAnchor.constraint(equalTo: leadingAnchor),
bottomLine.trailingAnchor.constraint(equalTo: trailingAnchor),
bottomLine.heightAnchor.constraint(equalToConstant: 1)
])
}
For multiple Text Field
override func viewDidLoad() {
configureTextField(x: 0, y: locationField.frame.size.height-1.0, width: locationField.frame.size.width, height:1.0, textField: locationField)
configureTextField(x: 0, y: destinationField.frame.size.height-1.0, width: destinationField.frame.size.width, height:1.0, textField: destinationField)
configureTextField(x: 0, y: originField.frame.size.height-1.0, width: originField.frame.size.width, height:1.0, textField: originField)
configureTextField(x: 0, y: nameField.frame.size.height-1.0, width: nameField.frame.size.width, height:1.0, textField: nameField)
locationField.text="Hello"
super.viewDidLoad()
// Do any additional setup after loading the view.
}
func configureTextField(x:CGFloat,y:CGFloat,width:CGFloat,height:CGFloat,textField:UITextField)
{
let bottomLine = CALayer()
bottomLine.frame = CGRect(x: x, y: y, width: width, height: height)
bottomLine.backgroundColor = UIColor.white.cgColor
textField.borderStyle = UITextBorderStyle.none
textField.layer.addSublayer(bottomLine)
}
Textfield bottom border set but some more issues for devices.So bottom border not fit in textfield.I retrieve that problem the code like this
It works fine
swift 4.2
let bottomLine = CALayer()
bottomLine.frame = CGRect(x: 0.0, y: textField.frame.height - 1, width: screenSize.width - 32, height: 1.0)
bottomLine.backgroundColor = UIColor(hex: 0xD5D5D5).cgColor
textField.borderStyle = UITextField.BorderStyle.none
textField.layer.addSublayer(bottomLine)
For swift 4. this works for me.
let myfield:UITextField = {
let mf=UITextField()
let atributePlaceHolder=NSAttributedString(string: "Text_description", attributes:[NSAttributedString.Key.foregroundColor :UIColor.darkGray])
mf.textColor = .gray
mf.attributedPlaceholder=atributePlaceHolder
mf.layer.borderColor = UIColor.black.cgColor
mf.layer.backgroundColor = UIColor.white.cgColor
mf.layer.borderWidth = 0.0
mf.layer.shadowOffset = CGSize(width: 0, height: 1.0)
mf.layer.shadowOpacity = 1.0
mf.layer.shadowRadius = 0.0
return mf
}()
