Creating two textfields with only bottom border swift - ios

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!

Text in UIView Border

I am currently working on a project in iOS (using XCode and Swift). I am trying to implement the following UITextFields for the login view:
I was thinking of different ways to go about doing this and they all seem complicated. It would be amazing if someone knows of a super easy way to do this or if there is already a cocoapod that can be used to create this TextView.
Here are a few ways I was thinking of doing it:
Just make a UITextField with a border and put a UILabel with a background matching the parent view's background, blocking out the part where "Login" and "Password" would show up. This would hide the border at these parts and would solve the issue. The problem with this approach is if the background is a gradient, pattern, or image. This can be seen in the following images:
If the user looks closely at the "EMAIL" and "PASSWORD" UILabels here it can be seen that it does not have a transparent background and that it has an set background color in order to block out the border of the UITextField.
Instead of doing this, I would like to actually stop the drawing of the border which brings me to a second possible method of implementation.
Using core graphics to manually draw the border of the UITextField, this would have to be dynamic since there can be different length strings ("Login) is 5 characters, "Password" is 8). This approach seems complicated because dealing with CoreGraphics can be annoying.
I wasn't able to come up with any other ways of implementing this but I'd appreciate it if there was a less cumbersome solution.
Try this extension. I have tried this and is working good.
extension UITextField {
func leftBorder() {
let leftBorder = CALayer()
leftBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(0.0), width: CGFloat(1.0), height: CGFloat(self.frame.size.height))
leftBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(leftBorder)
}
func rightBorder() {
let rightBorder = CALayer()
rightBorder.frame = CGRect(x: CGFloat(self.frame.size.width - 1), y: CGFloat(0.0), width: CGFloat(1.0), height: CGFloat(self.frame.size.height))
rightBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(rightBorder)
}
func bottomBorder() {
let bottomBorder = CALayer()
bottomBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(self.frame.size.height - 1), width: CGFloat(self.frame.size.width), height: CGFloat(1.0))
bottomBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(bottomBorder)
}
func topBorder1() {
let topBorder = CALayer()
topBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(0.0), width: CGFloat(25.0), height: CGFloat(1.0))
topBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(topBorder)
}
func topBorder2(position: CGFloat) {
let width = CGFloat(self.frame.size.width - position)
let topBorder2 = CALayer()
topBorder2.frame = CGRect(x: position, y: CGFloat(0), width: width, height: CGFloat(1.0))
topBorder2.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(topBorder2)
}
}
Call those extension methods in viewDidLayoutSubviews method like this..
override func viewDidLayoutSubviews() {
loginTextField.leftBorder()
loginTextField.rightBorder()
loginTextField.bottomBorder()
loginTextField.topBorder1()
let position = CGFloat(25 + loginLabel.frame.size.width + 10)
loginTextField.topBorder2(position: position)
}
This is how the initial story board looks like. I used a textfield and then placed a label above that textfield.
Note: I have used the label's width for some calculation.
And the result in the simulator is
I believe one method of doing this is by drawing the individual borders:
extension UITextField {
func border(position: CGFloat) {
let leftBorder = CALayer()
leftBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(0.0), width: CGFloat(1.0), height: CGFloat(self.frame.size.height))
leftBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(leftBorder)
let rightBorder = CALayer()
rightBorder.frame = CGRect(x: CGFloat(self.frame.size.width - 1), y: CGFloat(0.0), width: CGFloat(1.0), height: CGFloat(self.frame.size.height))
rightBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(rightBorder)
let bottomBorder = CALayer()
bottomBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(self.frame.size.height - 1), width: CGFloat(self.frame.size.width), height: CGFloat(1.0))
bottomBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(bottomBorder)
let topBorder = CALayer()
topBorder.frame = CGRect(x: CGFloat(0.0), y: CGFloat(0.0), width: CGFloat(25.0), height: CGFloat(1.0))
topBorder.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(topBorder)
let width = CGFloat(self.frame.size.width - position)
let topBorder2 = CALayer()
topBorder2.frame = CGRect(x: position, y: CGFloat(0), width: width, height: CGFloat(1.0))
topBorder2.backgroundColor = UIColor.black.cgColor
self.layer.addSublayer(topBorder2)
}
I do not think it is possible to do this with a corner radius. The only way that I can imagine doing this is by going into CoreGraphics, which is usually more work than it is worth. Take a look here

Swift make input transparent with only border-bottom

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

Add a bottom border to UITableView in swift?

I would like to add a bottom border to my table view in swift, which will act as a separator. I tried the answers to some other questions, but most of them included CGRectMake, which is now outdated. Any thoughts?
Here is the code I am using, which doesn't produce an error message, but doesn't work:
let border = CALayer()
let width = CGFloat(2.0)
border.borderColor = UIColor.darkGray.cgColor
border.frame = CGRect(x: 0, y: tableView.frame.size.height - width, width: tableView.frame.size.width, height: tableView.frame.size.height)
border.borderWidth = width
tableView.layer.addSublayer(border)
tableView.layer.masksToBounds = true
Thank you!

Underline UITextField does not work in StackView

I'm having multiple textfields for sign-up page and I have used stack view in it. When I try to assign underline colour to my UITextField it does not work. But if I do the same w/o StackView then it works fine.
extension UITextField {
func underlined() {
let border = CALayer()
let width = CGFloat(1.0)
border.borderColor = themeColor.cgColor
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
}
}
nameTextField.underlined()
ageTextField.underlined()

Swift UITextField Border bottom and shadow issues

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)
}
