I have created a text programmatically with a grey background using UILabel. Now I would like to add padding
to this paragraph/text. Also, it would be great if you could show me how to add margin
to my UILabel
as well.
import UIKit
final class SignUpViewController: UIViewController {
public let identifier = "Sign Up"
private let logoImage : UIImageView = {
let imageView = UIImageView()
imageView.layer.masksToBounds = true
imageView.contentMode = .scaleAspectFit
imageView.image = UIImage(named: "MyLogoWithTitle")
imageView.clipsToBounds = true
return imageView
}()
private let instructionText : UILabel = {
let label = UILabel()
label.text = "Please read terms and conditions below carefully before proceeding with the registration."
label.backgroundColor = UIColor().colorFromHex(hex: "#2C333C", opacity: 0.4)
label.numberOfLines = 0
label.tintColor = .white
return label
}()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
view.addSubview(logoImage)
view.addSubview(instructionText)
view.backgroundColor = UIColor().colorFromHex(hex: "#141920", opacity: 1.0)
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
logoImage.frame = CGRect(x: 0,
y: 0,
width: 140,
height: 60)
logoImage.center = CGPoint(x: view.center.x, y: view.height/5)
instructionText.frame = CGRect(
x: 5,
y: 5 + logoImage.bottom,
width: view.width - 20,
height: 50)
.integral
instructionText.layer.cornerRadius = 10
}
}
Notice that I created an extension to UIColor so that I can input hex color in this way - UIColor().colorFromHex(hex: "#2C333C", opacity: 0.4)
.
I am looking forward to hearing from you. Thank you.
You can insert this UILabel into the container (any UIView) and set its position inside.
But the simplest trick is to use UIButton instead of UILabel. You can configure UIEdgeInsets for padding.
So that UIButton does not act as a button simply set button.isUserInteractionEnabled = false.
By default, text in the button are placed in the center, but its position is easy to change with contentHorizontalAlignment and contentVerticalAlignment
And as a bonus, you can add icons right near to the text. :)
UPD.
Could you give me a simple example? I tried that way but I didn't get the result I expected. – Punreach Rany
let buttonUsedAsLabel = UIButton()
// Your question was about padding
// It's it!
buttonUsedAsLabel.titleEdgeInsets = UIEdgeInsets(top: 5, left: 20, bottom: 5, right: 20)
// Make it not user interactable as UILabel is
buttonUsedAsLabel.isUserInteractionEnabled = false
// set any other properties
buttonUsedAsLabel.setTitleColor(.white, for: .normal)
buttonUsedAsLabel.contentVerticalAlignment = .top
buttonUsedAsLabel.contentHorizontalAlignment = .left
// Set title propeties AFTER it was created with text because it's nullable
// You can use attributed title also
// Never use any (button.titleLabel) before its creation
// for example: (button.titleLabel?.text = "zzz") do nothing here
buttonUsedAsLabel.setTitle("This is the text", for: .normal)
buttonUsedAsLabel.titleLabel?.font = .systemFont(ofSize: 20, weight: .medium)
buttonUsedAsLabel.titleLabel?.numberOfLines = 0
buttonUsedAsLabel.titleLabel?.lineBreakMode = .byWordWrapping
// and so on
// ...
// This is the triсk :)
Of course, you can do it with a storyboard if prefer.
1. Add this class
PaddingLabel.swift
import UIKit
class PaddingLabel: UILabel {
var edgeInset: UIEdgeInsets = .zero
override func drawText(in rect: CGRect) {
let insets = UIEdgeInsets.init(top: edgeInset.top, left: edgeInset.left, bottom: edgeInset.bottom, right: edgeInset.right)
super.drawText(in: rect.inset(by: insets))
}
override var intrinsicContentSize: CGSize {
let size = super.intrinsicContentSize
return CGSize(width: size.width + edgeInset.left + edgeInset.right, height: size.height + edgeInset.top + edgeInset.bottom)
}
}
2. Add this code to your ViewController
let label = PaddingLabel()
override func viewDidLoad() {
super.viewDidLoad()
label.backgroundColor = UIColor().colorFromHex(hex: "#2C333C", opacity: 0.4)
//Setting the padding label
label.edgeInset = UIEdgeInsets(top: 5, left: 10, bottom: 5, right: 10)
}
The answer to the link below is that I wrote the same content based on the storyboard.
I use textfield
. Set padding and text in textfield. And do not allow editing.
extension UITextField {
func addLeftPadding() {
let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: 12, height: self.frame.height))
self.leftView = paddingView
self.leftViewMode = ViewMode.always
}
}
//ViewController
@IBOutlet weak var myTextField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
myTextField.addLeftPadding()
myTextField.isUserInteractionEnabled = false
myTextField.text = "your label text"
}
