I am trying to create 5 labels that are equally spaced in a custom view. But I am unaware of how to equally space the labels in order to achieve that.
Here is a complete class code with stackView Starting point for you
import UIKit
class ViewController: UIViewController {
private lazy var stackView : UIStackView = {
let stack = UIStackView()
stack.axis = .horizontal
stack.spacing = 10
stack.distribution = .fillEqually
stack.alignment = .fill
stack.translatesAutoresizingMaskIntoConstraints = false
return stack
}()
override func viewDidLoad() {
super.viewDidLoad()
setUpCostraints()
for _ in 1...5 {
let label = UILabel()
label.font = UIFont.boldSystemFont(ofSize: 30)
label.text = "✭"
if label.tag == 0 {
label.textColor = .red
} else {
label.textColor = .blue
}
stackView.addArrangedSubview(label)
}
}
override func viewDidLayoutSubviews() {
}
func setUpCostraints() {
view.addSubview(stackView)
stackView.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
stackView.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
stackView.heightAnchor.constraint(equalToConstant: 50).isActive = true
stackView.widthAnchor.constraint(equalToConstant: 200).isActive = true
}

recently, I decided to quit using storyboards on my IOS app. So, am presently learning everything now with code. I was trying to place a label below navigationBar view but I got an error and I don't know how to debug it. Please view my code and share your thoughts.
class SellBaseViewController: UIViewController {
lazy var container: UIStackView = {
let stackView = UIStackView(frame: .zero)
stackView.alignment = .fill
stackView.axis = .vertical
stackView.spacing = 2
stackView.willSetConstraints()
return stackView
}()
lazy var navHeader: UIView! = {
return self.navBar()
}()
lazy var firstLabel: UILabel! = {
return self.labelOne()
}()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
if !Authentication.shared.isAuthenticated {
showLogin()
} else {
self.setupInterface()
}
}
private func setupInterface() {
self.navigationController?.navigationBar.isHidden = true
self.embedInScrollView(content: self.container)
navHeader.willSetConstraints()
firstLabel.willSetConstraints()
self.container.addArrangedSubviews([self.navHeader!, self.firstLabel!])
DispatchQueue.main.async {
NSLayoutConstraint.activate([
self.navHeader.heightAnchor.constraint(equalToConstant: 44),
self.navHeader.widthAnchor.constraint(equalTo: self.view.widthAnchor),
self.navHeader.topAnchor.constraint(equalTo: self.container.topAnchor),
])
}
}
// MARK: NAVBAR
func navBar() -> UIView {
let navBar = UIView(frame: CGRect(origin: CGPoint(x: 0, y: 0), size: CGSize(width: self.view.frame.width, height: 44)))
navBar.backgroundColor = UIColor.constants.darkBlue
let backIcon = UIImage(named: "ic_back")?.withRenderingMode(.alwaysTemplate)
let returnButton = UIButton(type: .custom)
returnButton.imageView?.tintColor = UIColor.white
returnButton.setImage(backIcon, for: .normal)

label.text = "This is a Label"
self.view.addSubview(label)
return labelOne()
}
#objc func _return() {
self.backHome()
}
}
The navBar showed well, but when I added the label, the app kept crashing with this error. I don't know how to find out exactly what the error is:
Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffee6703fe8)
func labelOne() -> UILabel{
let label = UILabel()
label.textAlignment = .center
label.textColor = .white
label.font = UIFont(name: "Avenir-Light", size: 15.0)
label.text = "This is a Label"
self.view.addSubview(label)
return labelOne()
}
You did:
return labelOne()
You should do:
return label
Trying to create a UIScrollView and I cant seem to get my labels to appear as I would like them dead center.

It seems that when I add that last constraight with the topAnchor I get a blank screen. When I take that off I actually get the borders between the two views and I am able to do some scrolling.
Any help would be appreciated. Thank you
Did you give a value to the scrollView?
uiScrollView.contentSize.width = 1200
Then give the tutorialView the same width constraint with the other constraints.
NSLayoutConstraint.activate([
tutorialView.widthAnchor.constraint(equalToConstant: 1200),
tutorialView.heightAnchor.constraint(equalTo: uiScrollView.heightAnchor)
])
You have to add tutView.translatesAutoresizingMaskIntoConstraints = false when giving layout constraints in closure of tutorialView and also there are some mistakes in your code. So included some changes in your code and check updated code:
lazy var label : UILabel = {
let label = UILabel()
label.text = "center of container view.center of container view"
label.font = UIFont(name: "Bebas Neue", size: 23)!
label.textColor = .green
return label
}()

return newView

I am trying to add an UIView with a label, and want to set constraints to place the label in the center horizontally as well as vertically. But the code doesn't place it as I want. Below is the code. The label is presented on the top left hand corner of the screen instead of the center of the screen.
class TestViewController: UIViewController {
var title = UIView()
override func viewDidLoad() {
super.viewDidLoad()
func presentTitle ()
}
func presentTitle () {
title.backgroundColor = UIColor.black
title.textColor = UIColor.white
title.font = UIFont(name: "Helvetica", size: 30)
title.textAlignment = .center
title.backgroundColor = .lightGray
title.numberOfLines = 1
title..text = vmTitleTransferredFromTaskAnalysisDetail!
self.view.addSubview(title)
title.translatesAutoresizingMaskIntoConstraints = false
title.centerXAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerXAnchor).isActive = true
title.centerYAnchor.constraint(equalTo: view.safeAreaLayoutGuide.centerYAnchor).isActive = true
title.eadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor).isActive = true
title.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor).isActive = true
self.view = title
}
}
I'm following a tutorial to create an interactive popup animation (http://www.swiftkickmobile.com/building-better-app-animations-swift-uiviewpropertyanimator/), and now would like to add buttons to the popup rather than have static text as in the tutorial.
The animation works fine, but the buttons are not detecting touch. Touching the button causes the animation to reverse, instead of printing my "test" statement.
From research, it looks to either be an issue with view hierarchies, the animation disabling the button touch, or layout/constraint issues with the button. I've tried addressing the above issues, but nothing has worked, was hoping someone might be able to help?
I've left out the code pertaining to the animation since I think the issue is to do with layout (and the animation seems to be working fine) - but it's still a lot; apologies in advance for the large amount of code.

***For anyone else having the same issue, here is how I solved it, thanks to #OverD:
I removed the reviewsImageView completely (because that was only for color in my case, and I can easily add the color to the UIButton instead) Then instead of adding the buttons to the popupView, I added them to the stack view, and the stack view to the popupView. Lastly, my syntax for addTarget was not correct, and for some reason changing it to touchDown instead of touchUpInside made it work.
I noticed from the provided code that you are adding the same buttons multiple times, once as a subview of the popView and once in the stackView. Also you are not assigning any targets for the buttons.
I hope this helps
I am one week into Swift programing and I want to build my first Application with Autolayout.
The current state of my app is that I generate a bunch of PictureCell in my ViewController. Their size is based on a slider value (and also calculated in the ViewController). This works just fine.
My struggle is customizing the inside of my PictureCell. My goal is to have a Label in the cell which font size is automatically resized when I resize the cell.
At the current state I can resize the Cell and the UITextView like I want, but I cannot resize the font within the Textview because it's constant is just called when it is initialized (I guess).
How can I address this problem in a good way?
Due to a not understanding of Swifts logic I have to post the whole code of the PictureCell:
class PictureCell: UICollectionViewCell {
override init(frame: CGRect) {
super.init(frame: frame)
self.translatesAutoresizingMaskIntoConstraints = false
self.layer.cornerRadius = self.bounds.width / 20
self.clipsToBounds = true
setupViews()
}
let descriptionTextView: UITextView = {
let textView = UITextView()
textView.text = "Header"
textView.textColor = .black
textView.backgroundColor = .white
textView.translatesAutoresizingMaskIntoConstraints = false
textView.textAlignment = .center
textView.isEditable = false
textView.isScrollEnabled = false
textView.sizeToFit()
textView.font = UIFont.boldSystemFont(ofSize: textView.contentSize.height / 2) // Resize that
textView.layer.borderWidth = 2
textView.layer.borderColor = UIColor.red.cgColor
return textView
}()
var mainPicture: UIImageView = {
let imageView = UIImageView()
imageView.contentMode = .scaleAspectFill
imageView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
imageView.clipsToBounds = true
return imageView
}()
func setPictureForIndex(index: Int) {
self.mainPicture.image = UIImage(named: "color\(index)")
}
func setupViews() {
addSubview(mainPicture)
confMainPicture()
addSubview(descriptionTextView)
confDescriptionTextView()
}
func confMainPicture() {
mainPicture.translatesAutoresizingMaskIntoConstraints = false
mainPicture.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
mainPicture.heightAnchor.constraint(equalTo: self.heightAnchor).isActive = true
mainPicture.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
mainPicture.bottomAnchor.constraint(equalTo: self.bottomAnchor).isActive = true
}
func confDescriptionTextView(){
descriptionTextView.translatesAutoresizingMaskIntoConstraints = false
descriptionTextView.widthAnchor.constraint(equalTo: self.widthAnchor).isActive = true
descriptionTextView.heightAnchor.constraint(equalTo: mainPicture.heightAnchor, multiplier: 0.25).isActive = true
descriptionTextView.topAnchor.constraint(equalTo: self.topAnchor).isActive = true
}
Too small for the text
Just fine
Too big to look good
This Code solved my problem more or less:
It doesn't work properly if the Cell is really small but it's better than the starting point and maybe someone can use it.
class PictureCell: UICollectionViewCell {
