let bottomBorder = CALayer()
let borderWidth = CGFloat(1.0)
bottomBorder.borderColor = UIColor(hex: 0xf5f5f5).CGColor
bottomBorder.frame = CGRect(x: 0, y: summary.frame.size.height - borderWidth, width: summary.frame.size.width, height: summary.frame.size.height)
bottomBorder.borderWidth = borderWidth
self.summary.layer.addSublayer(bottomBorder)
self.summary.layer.masksToBounds = true
I know how to add a bottom border, but when I apply the same principle to "topBorder", one of them disappears.
You can add top and bottom boarder using following code. you code have just framing issue.
let topBorder = CALayer()
let topHeight = CGFloat(1.0)
topBorder.borderColor = UIColor.blackColor().CGColor
topBorder.frame = CGRect(x: 0, y: 0, width: summary.frame.size.width, height: topHeight)
topBorder.borderWidth = summary.frame.size.width
self.summary.layer.addSublayer(topBorder)
let bottomBorder = CALayer()
let borderHeight = CGFloat(1.0)
bottomBorder.borderColor = UIColor.blackColor().CGColor
bottomBorder.frame = CGRect(x: 0, y: summary.frame.size.height - borderHeight, width: summary.frame.size.width, height: borderHeight)
bottomBorder.borderWidth = summary.frame.size.width
self.summary.layer.addSublayer(bottomBorder)
self.summary.layer.masksToBounds = true
I think it's your frames, review and modify this as necessary:
*Note this function was added as an extension to UITextView
func addBorders(color:UIColor) {
let bottomBorder = CALayer()
bottomBorder.backgroundColor = color.CGColor
bottomBorder.frame = CGRectMake(0, CGRectGetHeight(bounds) - 1, CGRectGetWidth(bounds), 1)
bottomBorder.name = "BottomBorder"
layer.addSublayer(bottomBorder)
let topBorder = CALayer()
topBorder.backgroundColor = color.CGColor
topBorder.frame = CGRectMake(0, 0, CGRectGetWidth(bounds), 1)
topBorder.name = "TopBorder"
layer.addSublayer(topBorder)
}
var bottomBorder = CALayer()
bottomBorder.frame = CGRect(x:0.0, y:self.descriptionTextView.frame.size.height - 1, width:self.descriptionTextView.frame.size.width, height: 1.0)
bottomBorder.backgroundColor = UIColor(hex:K.NODD_RED_HEX).cgColor
self.descriptionTextView.layer.addSublayer(bottomBorder)

I have create bottom border of textfields it is showing on all devices from 6 and above but on below 6 it is not showing ..it is showing empty placeholder I have tested on 5s
I am using this code
func designTextfields(){
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: emailField.frame.size.height - width, width: emailField.frame.size.width, height: emailField.frame.size.height)
border.borderWidth = width
emailField.layer.addSublayer(border)
emailField.layer.masksToBounds = true
let border1 = CALayer()
let width1 = CGFloat(2.0)
border1.borderColor = UIColor.darkGray.cgColor
border1.frame = CGRect(x: 0, y: passField.frame.size.height - width1, width: passField.frame.size.width, height: passField.frame.size.height)
border1.borderWidth = width1
passField.layer.addSublayer(border1)
passField.layer.masksToBounds = true
}
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
How can I create a textField with transparent background and only border bottom?
I have tried this code:
textField.backgroundColor = .clear
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.darkGrayColor().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
But it isn't working.
Here's an alternative implementation using a UIView rather than a CALayer.
let line = UIView()
line.frame.size = CGSize(width: textField.frame.size.width, height: 1)
line.frame.origin = CGPoint(x: 0, y: textField.frame.maxY - line.frame.height)
line.backgroundColor = UIColor.darkGray
line.autoresizingMask = [.flexibleWidth, .flexibleTopMargin]
textField.addSubview(line)
Your code is correct. Problem is only with your border height which is now "textField.frame.size.height" change it to 1.0.(Change your border frame code).
Please try this :
txtField .borderStyle = .none
It may help you.... :)
extension UITextField {
func setBottomBorder(borderColor: CGColor = UIColor.white.cgColor,
backgroundColor: CGColor = UIColor.clear.cgColor) {
self.borderStyle = .none
self.layer.backgroundColor = backgroundColor
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = borderColor
border.frame = CGRect(x: 0, y: self.frame.size.height - width, width: self.frame.size.width, height: self.frame.size.height)
border.borderWidth = width
self.layer.addSublayer(border)
self.layer.masksToBounds = true
}
}
This worked for me.
Then you can just call
yourTextField.SetBottomBorder(borderColor: UIColor.white.cgColor, backgroundColor: UIColor.clear.cgColor)
Just add this line with your code :-
border.backgroundColor = UIColor.black.cgColor
This code seems to be working fine for me though, setting the backgroundColor to clear fix this
textField.backgroundColor = .clear
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)
}
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)
}
}
