It is necessary to leave only the bottom border at UITextField. For some reason my code does not work.
let bottomLine = CALayer()
bottomLine.frame = CGRect(x:0.0, y:1.0, width: myTextField.frame.width,
height: myTextField.frame.height - 1)
bottomLine.backgroundColor = UIColor.white.cgColor
myTextField.borderStyle = UITextBorderStyle.None
myTextField.layer.addSublayer(bottomLine)
Replace this
bottomLine.frame = CGRect(x:0.0, y:1.0, width: myTextField.frame.width,height: myTextField.frame.height - 1)
with
bottomLine.frame = CGRect(x:0.0, y:myTextField.frame.height - 1, width: myTextField.frame.width,height: 1)
In my case work with adding :
myTextFeld.wantsLayer = true
I'm trying to create two UITextFields that both only have the bottom border, I got some code from another StackOverflow and it worked. However, when I copy and pasted the code again for my second TextField it only shows one TextField with the bottom border.
Here is the code:
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.gray.cgColor
border.frame = CGRect(x: 0, y: emailText.frame.size.height -
width, width: emailText.frame.size.width, height:
emailText.frame.size.height)
border.frame = CGRect(x: 0, y: passwordText.frame.size.height
- width, width: passwordText.frame.size.width, height:
passwordText.frame.size.height)
border.borderWidth = width
passwordText.layer.addSublayer(border)
passwordText.layer.masksToBounds = true
border.borderWidth = width
emailText.layer.addSublayer(border)
emailText.layer.masksToBounds = true
Thanks for the help!
CALayers are instance-based, that means if you added the layer to a view, you cannot add it to a new one without removing it from the first view. Create two instances of CALayers or better yet, make an extension that produces the desired result.
Create separate border object for email textfield and username textfield.
let emailborder = CALayer()
let passwordborder = CALayer()
let width = CGFloat(2.0)
emailborder.borderColor = UIColor.gray.cgColor
emailborder.frame = CGRect(x: 0, y: emailText.frame.size.height -
width, width: emailText.frame.size.width, height:
emailText.frame.size.height)
passwordborder.frame = CGRect(x: 0, y: passwordText.frame.size.height
- width, width: passwordText.frame.size.width, height:
passwordText.frame.size.height)
passwordborder.borderWidth = width
passwordText.layer.addSublayer(passwordborder)
passwordText.layer.masksToBounds = true
emailborder.borderWidth = width
emailText.layer.addSublayer(emailborder)
emailText.layer.masksToBounds = true
You cant use the same view for both textfield. Use a copy of border for the second one. Easiest way to make this work is to refine a variable as border2 and set it up and sublayer it. Don't forget to remove your duplicate frame assign for boarder.
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.gray.cgColor
border.frame = CGRect(x: 0, y: emailText.frame.size.height - width, width: emailText.frame.size.width, height: emailText.frame.size.height)
let border2 = CALayer() border2.borderColor = border.borderColor border2.frame = border.frame;
border.borderWidth = width
passwordText.layer.addSublayer(border)
passwordText.layer.masksToBounds = true
border.borderWidth = width
emailText.layer.addSublayer(border2)
emailText.layer.masksToBounds = true
The best you could without writing redundant code is that you create a function, pass the textfields you want to border as parameters and keep the styling code in there like so:
func setBorder(tf: UITextField) {
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.gray.cgColor
border.frame = CGRect(x: 0, y: tf.frame.size.height - width,
width: tf.frame.size.width, height:
tf.frame.size.height)
border.borderWidth = width
tf.layer.addSublayer(border)
tf.layer.masksToBounds = true
}
Call this function in viewDidLoad:
setBorder(tf: emailText)
setBorder(tf: passwordText)
Hope this helps!
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 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
}()
iOS noob here
When I add a default UITextField to the ViewController, it looks like this:
My designer would like me to make the UITextField look like this (i.e. background is transparent, and just has an underline:
How do I do this? Should be asking my designer for an image to set as background for the UITextField. What should the image look like? Should the image be = the blue background + the underline (minus the number i guess)
Is that right?
UPDATE:
Based on direction below (from #Ashish Kakkad), added this code in Swift to ViewDidLoad:
var bottomLine = CALayer()
bottomLine.frame = CGRectMake(0.0, view.frame.height - 1, view.frame.width, 1.0)
bottomLine.backgroundColor = UIColor.whiteColor().CGColor
tf_editPassword.borderStyle = UITextBorderStyle.None
tf_editPassword.layer.addSublayer(bottomLine)
This almost works, but the problem is that all side borders disappear, I want just the bottom line to stay.
Try this code :
Obj-C
CALayer *bottomLine = [CALayer layer];
bottomLine.frame = CGRectMake(0.0f, self.frame.size.height - 1, self.frame.size.width, 1.0f);
bottomLine.backgroundColor = [UIColor whiteColor].CGColor;
[myTextField setBorderStyle:UITextBorderStyleNone];
[myTextField.layer addSublayer:bottomLine];
Swift
var bottomLine = CALayer()
bottomLine.frame = CGRectMake(0.0, view.frame.height - 1, view.frame.width, 1.0)
bottomLine.backgroundColor = UIColor.whiteColor().CGColor
myTextField.borderStyle = UITextBorderStyle.None
myTextField.layer.addSublayer(bottomLine)
Hope it helps
If you are using the auto-layout then try to do this code inside the viewDidLayoutSubviews method.
#Ashish Kakkad has posted the right code but the reason it might not be working for #user1406716 is because when there is no text in the textfield, the height and width of the frame are 0 so maybe you can try the following :
Obj-C :
CALayer *bottomLine = [CALayer layer];
bottomLine.frame = CGRectMake(0.0f, 75 - 1, 300, 1.0f);
bottomLine.backgroundColor = [UIColor whiteColor].CGColor;
[myTextField setBorderStyle:UITextBorderStyleNone];
[myTextField.layer addSublayer:bottomLine];
Swift :
var bottomLine = CALayer()
bottomLine.frame = CGRectMake(0.0, 75 - 1, 300, 1.0)
bottomLine.backgroundColor = UIColor.whiteColor().CGColor
myTextField.borderStyle = UITextBorderStyle.None
myTextField.layer.addSublayer(bottomLine)
This will ensure that the line is visible even when there is no text in the textfield.
Use this Extension for UITextField
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
}
}
Call the above function in ViewDidLoad() and display the textfield with an underline.
myTextField.setUnderLine()
To update this with Swift 3:
let bottomLine = CALayer()
bottomLine.frame = CGRect(origin: CGPoint(x: 0, y:first.frame.height - 1), size: CGSize(width: first.frame.width, height: 1))
bottomLine.backgroundColor = UIColor.white.cgColor
first.borderStyle = UITextBorderStyle.none
first.layer.addSublayer(bottomLine)
Delete borders and add underline - Swift 5:
extension UITextField {
func addUnderLine () {
let bottomLine = CALayer()
bottomLine.frame = CGRect(x: 0.0, y: self.bounds.height + 3, width: self.bounds.width, height: 1.5)
bottomLine.backgroundColor = UIColor.lightGray.cgColor
self.borderStyle = UITextField.BorderStyle.none
self.layer.addSublayer(bottomLine)
}
}
