I'm setting constraints to image view programmatically like so:
imgScrollView = UIScrollView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
imgScrollView.showsHorizontalScrollIndicator = false
imgScrollView.showsVerticalScrollIndicator = false
imgScrollView.bouncesZoom = false
imgScrollView.bounces = false
view.addSubview(imgScrollView)
imgScrollView.translatesAutoresizingMaskIntoConstraints = false
imgScrollView.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
imgScrollView.bottomAnchor.constraint(equalTo: toolBar.topAnchor, constant: -100).isActive = true
imgScrollView.leftAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leftAnchor, constant: 0).isActive = true
imgScrollView.rightAnchor.constraint(equalTo: view.safeAreaLayoutGuide.rightAnchor, constant: 0).isActive = true
// add image view to scrollview
imgView = UIImageView(frame: CGRect(x: 0, y: 0,width: 100, height: 100))
imgScrollView.addSubview(imgView)
imgView.translatesAutoresizingMaskIntoConstraints = false
imgView.topAnchor.constraint(equalTo: imgScrollView.contentLayoutGuide.topAnchor, constant: 0).isActive = true
imgView.bottomAnchor.constraint(equalTo: imgScrollView.contentLayoutGuide.bottomAnchor, constant: 0).isActive = true
imgView.leftAnchor.constraint(equalTo: imgScrollView.contentLayoutGuide.leftAnchor, constant: 0).isActive = true
imgView.rightAnchor.constraint(equalTo: imgScrollView.contentLayoutGuide.rightAnchor, constant: 0).isActive = true
imgView.widthAnchor.constraint(equalTo: imgScrollView.widthAnchor, multiplier: 1).isActive = true
Now later on with button tap I'm adding additional constraint
imgView.heightAnchor.constraint(equalTo: imgScrollView.heightAnchor, multiplier: 1).isActive = true
However the constraint is not being added. Why is it happening?
Your implementation logic working for me.
Left image show implementation without height constraint.
Right image show button pressed with height constraint.

}
}

I am working on a canvas view where I am trying to add image to a UIView and a text to a UIView, on satisfying some conditions.
The issue is, I am not able to add label to my UIView after satisfying the required condition. I tried this code separately without any functions and conditions and it is working fine. But if I try and run it as given below it doesn't show me the label on the UIView.
[Note- The code here is working fine for imageView.]
I tried various constraint combinations like, centerX, centerY, width, height or leading, trailing, top, bottom. But nothing is working. Please help.
My code is as below: -
class CanvasViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
createCanvasOnAspectRatio()
}
func createCanvasOnAspectRatio() {
let View1: UIView = {
let viewView = UIView()
viewView.translatesAutoresizingMaskIntoConstraints = false
viewView.contentMode = .scaleAspectFit
print(UserDefaults.standard.bool(forKey: "backgroundColourSelected"))
if UserDefaults.standard.bool(forKey: "backgroundColourSelected") {
viewView.backgroundColor = self.viewColor
}else {
viewView.backgroundColor = .white
}
viewView.clipsToBounds = true
return viewView
}()
self.canvasView.addSubview(View1)
View1.centerXAnchor.constraint(equalTo: canvasView.centerXAnchor, constant: 0).isActive = true
View1.centerYAnchor.constraint(equalTo: canvasView.centerYAnchor, constant: 0).isActive = true
View1.widthAnchor.constraint(equalTo: canvasView.widthAnchor, constant: 0).isActive = true
View1.heightAnchor.constraint(equalTo: canvasView.widthAnchor, multiplier: aspectRatio).isActive = true
if UserDefaults.standard.bool(forKey: "imageSelectedFromGallexy") == true {
for item in 0..<self.imagesForGallery.count {
let image = imagesForGallery[item]
let image_View: UIImageView = {
let imageV = UIImageView()
imageV.image = image
imageV.contentMode = .scaleAspectFill
imageV.translatesAutoresizingMaskIntoConstraints = false
imageV.clipsToBounds = true
return imageV
}()
View1.addSubview(image_View)
image_View.topAnchor.constraint(equalTo: View1.topAnchor, constant: 0).isActive = true
image_View.bottomAnchor.constraint(equalTo: View1.bottomAnchor, constant: 0).isActive = true
image_View.leadingAnchor.constraint(equalTo: View1.leadingAnchor, constant: 0).isActive = true
image_View.trailingAnchor.constraint(equalTo: View1.trailingAnchor, constant: 0).isActive = true
}
}
if UserDefaults.standard.bool(forKey: "addTextToCanvas") == true {
let labelTextView: UILabel = {
let labelView = UILabel()
//labelView.frame = CGRect(x: 0.0, y: 0.0, width: 50.0, height: 30.0)
labelView.translatesAutoresizingMaskIntoConstraints = false
labelView.textColor = .green
labelView.text = "Hello"
labelView.font = UIFont(name: "Avenir-Medium", size: 15.0)
labelView.textAlignment = .center
// labelView.clipsToBounds = true
return labelView
}()
View1.addSubview(labelTextView)
labelTextView.centerXAnchor.constraint(equalTo: View1.centerXAnchor, constant: 0).isActive = true
labelTextView.centerYAnchor.constraint(equalTo: View1.centerYAnchor, constant: 0).isActive = true

UserDefaults.standard.set(false, forKey: "addTextToCanvas")
}
}
}
I have three views on the bottom of the view. I'm trying to make them have the same size and the size can be resized automatically depending on the size of the container view. I'd like to do it programmatically.
Here's how I want them to look
Here's how it looks by my current code
import UIKit
class ViewController: UIViewController {
var view1 = UIView(frame: CGRect(x: 100, y: 100, width: 100, height: 100))
var view2 = UIView(frame: CGRect(x: 300, y: 300, width: 50, height: 50))
var view3 = UIView(frame: CGRect(x: 400, y: 500, width: 70, height: 70))
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(view1)
view.addSubview(view2)
view.addSubview(view3)
view1.backgroundColor = .orange
view2.backgroundColor = .black
view3.backgroundColor = .gray
view1.translatesAutoresizingMaskIntoConstraints = false
view2.translatesAutoresizingMaskIntoConstraints = false
view3.translatesAutoresizingMaskIntoConstraints = false
// view1.topAnchor.constraint(equalTo: view.topAnchor, constant: 10).isActive = true
view1.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -10).isActive = true
view1.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: -10).isActive = true
view1.widthAnchor.constraint(equalTo: view.widthAnchor, constant: view.frame.size.width*0.01).isActive = true
view2.heightAnchor.constraint(equalToConstant: view.frame.size.height*0.1).isActive = true
//view2.topAnchor.constraint(equalTo: view.topAnchor, constant: 10).isActive = true
view2.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -10).isActive = true
view2.leadingAnchor.constraint(equalTo: view1.leadingAnchor, constant: view.frame.size.width*(2/3)).isActive = true
view2.widthAnchor.constraint(equalTo: view1.widthAnchor, constant: 0).isActive = true
view2.heightAnchor.constraint(equalTo: view1.heightAnchor, constant: 0).isActive = true
// view3.topAnchor.constraint(equalTo: view.topAnchor, constant: 10).isActive = true
view3.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -10).isActive = true
view3.leadingAnchor.constraint(equalTo: view2.leadingAnchor, constant: 10).isActive = true
view3.widthAnchor.constraint(equalTo: view2.widthAnchor, constant: 0).isActive = true
view3.heightAnchor.constraint(equalTo: view2.heightAnchor, constant: 0).isActive = true
}
}
Here, you can use the concept of UIStackView. Here, you can get your desired output using the following code(sample demo)
import UIKit
class ViewController: UIViewController {
var view1 = UIView()
var view2 = UIView()
var view3 = UIView()
override func viewDidLoad() {
super.viewDidLoad()
let stackView = UIStackView(arrangedSubviews: [view1, view2, view3])
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.axis = .horizontal
stackView.distribution = .fillEqually
stackView.spacing = 50 //add amount of space between your views
view.addSubview(stackView)
view1.backgroundColor = .orange
view2.backgroundColor = .black
view3.backgroundColor = .gray
stackView.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: -10).isActive = true
stackView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor, constant: 10).isActive = true
stackView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor, constant: -10).isActive = true
stackView.heightAnchor.constraint(equalToConstant: view.frame.size.height*0.1).isActive = true
}
}
For more about UIStackView with example check this: https://nshipster.com/uistackview
Output:
Welcome to Stackoverflow. Please read on UIStackView. And by using that stackView, you can easily achieve what you want to achieve in your screenshot.
import UIKit
class ViewController: UIViewController {
var view1 = UIView()
var view2 = UIView()
var view3 = UIView()
lazy var stackView: UIStackView = {
return UIStackView(arrangedSubviews: [
self.view1,
self.view2,
self.view3
])
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(stackView)
view1.backgroundColor = .orange
view2.backgroundColor = .black
view3.backgroundColor = .gray
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.axis = .horizontal
stackView.distribution = .equalSpacing
stackView.alignment = .center
view1.translatesAutoresizingMaskIntoConstraints = false
view2.translatesAutoresizingMaskIntoConstraints = false
view3.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
self.stackView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: 16),
self.stackView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor, constant: -16),
self.stackView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -16),
self.view1.heightAnchor.constraint(equalToConstant: view.frame.size.height*0.1),
self.view1.widthAnchor.constraint(equalToConstant: view.frame.size.height*0.1),
self.view2.heightAnchor.constraint(equalToConstant: view.frame.size.height*0.1),
self.view2.widthAnchor.constraint(equalToConstant: view.frame.size.height*0.1),
self.view3.heightAnchor.constraint(equalToConstant: view.frame.size.height*0.1),
self.view3.widthAnchor.constraint(equalToConstant: view.frame.size.height*0.1)
])
}
}
RESULT:
I have a view and inside the view there is a scrollview. I setup the scrollview programmatically. But for some reason the scrollview fits not perfectly in the view. The scrollview has the same frame as the view. But for some reason it is not working.
The white view is the view where the scrollview is in it.
The scrollview is the green view. I set the background color to green.
In the scrollview there is an image view.
My Code:
var scrollView: UIScrollView = {
let scrollView = UIScrollView()
scrollView.showsHorizontalScrollIndicator = false
scrollView.alwaysBounceVertical = false
scrollView.alwaysBounceHorizontal = false
scrollView.isPagingEnabled = true
return scrollView
}()
override func viewDidLoad() {
super.viewDidLoad()
scrollView.backgroundColor = .green
scrollView.frame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.size.width, height: contentView.frame.height) contentView.addSubview(scrollView)
scrollView.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 0).isActive = true
scrollView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 0).isActive = true
scrollView.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: 0).isActive = true
scrollView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: 0).isActive = true
}
var frame = CGRect.zero
func viewTutorial() {
for i in 0..<arrayOfTutorilImages.count {
frame.origin.x = scrollView.frame.size.width * CGFloat((i))
frame.size = scrollView.frame.size
let imageView = UIImageView(frame: frame)
imageView.image = UIImage(named: arrayOfTutorilImages[i])
imageView.contentMode = .scaleAspectFit
self.scrollView.addSubview(imageView)
}
scrollView.contentSize = CGSize(width: (scrollView.frame.size.width * CGFloat(arrayOfTutorilImages.count)), height: scrollView.frame.size.height)
scrollView.delegate = self
}
extension TutorialViewController: UIScrollViewDelegate {
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
let pageNumber = scrollView.contentOffset.x / scrollView.frame.size.width
pageControl.currentPage = Int(pageNumber)
}
}
UPDATE:
I changed the frame and added constraints to the scrollview. Now it look like this. The images is not resizing (this image is the blue drawing)
I would recommend you to use constrains:
self.scrollView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor),
self.scrollView.trailingAnchor.constraint(equalTo: self.view.trailingAnchor),
self.scrollView.topAnchor.constraint(equalTo: self.view.topAnchor),
self.scrollView.bottomAnchor.constraint(equalTo: self.view.bottomAnchor)
You can create a helper method for this if you have like a UIView+Helpers, and use just one line.
extension UIView {
public func pinToEdges(of view: UIView,
topConstant: CGFloat = 0,
leadingConstant: CGFloat = 0,
bottomConstant: CGFloat = 0,
trailingConstant: CGFloat = 0) {
NSLayoutConstraint.activate([
self.topAnchor.constraint(equalTo: view.topAnchor, constant: topConstant),
self.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: leadingConstant),
self.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: bottomConstant),
self.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: trailingConstant),
])
}
}
And then use:
self.scrollView.pinToBounds(self.view)
And remember of course to set the translatesAutoresizingMaskIntoConstraints to false
I have some issues using translatesAutoresizingMaskIntoConstraints.
I am creating a scrollview where you can swipe to the left or right. Every time you get a another image. But for some reason I can't swipe if translatesAutoresizingMaskIntoConstraints = false.
This is with translatesAutoresizingMaskIntoConstraints = false (in this case, I can't swipe left or right)
But if I set translatesAutoresizingMaskIntoConstraints = true it look like this and I can swipe to the left and right. The problem is, that the layout is messed up.
My code:
var scrollView: UIScrollView = {
let scrollView = UIScrollView()
scrollView.showsHorizontalScrollIndicator = false
scrollView.showsVerticalScrollIndicator = false
scrollView.translatesAutoresizingMaskIntoConstraints = false
scrollView.alwaysBounceVertical = false
scrollView.alwaysBounceHorizontal = false
scrollView.isPagingEnabled = true
return scrollView
}()
override func viewDidLoad() {
super.viewDidLoad()
scrollView.frame = contentView.frame
contentView.addSubview(scrollView)
scrollView.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 0).isActive = true
scrollView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 0).isActive = true
scrollView.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: 0).isActive = true
scrollView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: 0).isActive = true
}
var frame = CGRect.zero
func viewTutorial() {
for i in 0..<arrayOfTutorilImages.count {
frame.origin.x = scrollView.frame.size.width * CGFloat((i))
frame.size = scrollView.frame.size
let imageView = UIImageView(frame: frame)
imageView.image = UIImage(named: arrayOfTutorilImages[i])
imageView.contentMode = .scaleAspectFit
imageView.backgroundColor = .red
imageView.translatesAutoresizingMaskIntoConstraints = false
self.scrollView.addSubview(imageView)
imageView.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 0).isActive = true
imageView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 0).isActive = true
imageView.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: 0).isActive = true
imageView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: 0).isActive = true
}
scrollView.contentSize = CGSize(width: (scrollView.frame.size.width * CGFloat(arrayOfTutorilImages.count)), height: scrollView.frame.size.height)
scrollView.delegate = self
}
extension TutorialViewController: UIScrollViewDelegate {
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
let pageNumber = scrollView.contentOffset.x / scrollView.frame.size.width
pageControl.currentPage = Int(pageNumber)
}
}
You need to add constraints probably , You can try
class TutorialViewController: UIViewController {
var scrollView: UIScrollView = {
let scrollView = UIScrollView()
scrollView.showsHorizontalScrollIndicator = false
scrollView.showsVerticalScrollIndicator = false
scrollView.translatesAutoresizingMaskIntoConstraints = false
scrollView.alwaysBounceVertical = false
scrollView.alwaysBounceHorizontal = false
scrollView.isPagingEnabled = true
return scrollView
}()
override func viewDidLoad() {
super.viewDidLoad()
contentView.addSubview(scrollView)
scrollView.leftAnchor.constraint(equalTo: contentView.leftAnchor, constant: 0).isActive = true
scrollView.topAnchor.constraint(equalTo: contentView.topAnchor, constant: 0).isActive = true
scrollView.rightAnchor.constraint(equalTo: contentView.rightAnchor, constant: 0).isActive = true
scrollView.bottomAnchor.constraint(equalTo: contentView.bottomAnchor, constant: 0).isActive = true
viewTutorial()
}
func viewTutorial() {
var con:UIView = scrollView
for i in 0..<arrayOfTutorilImages.count {
let imageView = UIImageView(frame: CGRect.zero)
imageView.image = UIImage(named: arrayOfTutorilImages[i])
imageView.contentMode = .scaleAspectFit
imageView.backgroundColor = .red
imageView.translatesAutoresizingMaskIntoConstraints = false
self.scrollView.addSubview(imageView)
if con == scrollView {
imageView.leftAnchor.constraint(equalTo: con.leftAnchor, constant: 0).isActive = true
}
else {
imageView.leftAnchor.constraint(equalTo: con.rightAnchor, constant: 0).isActive = true
}
imageView.topAnchor.constraint(equalTo: scrollView.topAnchor, constant: 0).isActive = true
if i == arrayOfTutorilImages.count - 1 {
imageView.rightAnchor.constraint(equalTo: scrollView.rightAnchor, constant: 0).isActive = true
}
imageView.bottomAnchor.constraint(equalTo: scrollView.bottomAnchor, constant: 0).isActive = true
imageView.widthAnchor.constraint(equalTo: view.widthAnchor, constant: 0).isActive = true
con = imageView
}
scrollView.delegate = self
}
}
extension TutorialViewController: UIScrollViewDelegate {
func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
let pageNumber = scrollView.contentOffset.x / scrollView.frame.size.width
}
}
Don't set frames when using constrraints
Add Scrollview frame when create
var scrollView: UIScrollView = {
let scrollView = UIScrollView(frame:.zero)
//other properties
return scrollView
}()
ImageView constraints same as for ScrollView.
That is the reason why you can't swipe, because all your images have the same constraints, and they are located one over another.
You should do smth like:
imageView.translatesAutoresizingMaskIntoConstraints = true
imageView.frame.size = contentView.frame.size
imageView.frame.origin = CGPoint(x: imageIndex * contentView.frame.size.width, y: 0.0)
I'm trying to creating a reusable UIView subclass, with a UILabel and UIImageView as subviews. My view subclass should adjust its width according to the label's width.
Here is my class-
class CustomView: UIView {
private var infoLabel: UILabel!
private var imageView: UIImageView!
override init(frame: CGRect) {
super.init(frame: frame)
infoLabel = UILabel(frame: CGRect.zero)
imageView = UIImageView(frame: CGRect.zero)
addSubview(infoLabel)
addSubview(imageView)
infoLabel.backgroundColor = .white
imageView.backgroundColor = .gray
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func updateConstraints() {
super.updateConstraints()
infoLabel.translatesAutoresizingMaskIntoConstraints = false
imageView.translatesAutoresizingMaskIntoConstraints = false
infoLabel.leadingAnchor.constraint(
equalTo: self.leadingAnchor, constant: 5).isActive = true
// infoLabel.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
infoLabel.topAnchor.constraint(equalTo: self.topAnchor, constant: 5).isActive = true
infoLabel.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 5).isActive = true
imageView.leadingAnchor.constraint(
equalTo: infoLabel.trailingAnchor, constant: 10).isActive = true
//imageView.trailingAnchor.constraint(
//equalTo: self.trailingAnchor, constant: 10).isActive = true
//imageView.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
imageView.widthAnchor.constraint(equalToConstant: 25).isActive = true
imageView.topAnchor.constraint(equalTo: self.topAnchor, constant: 5).isActive = true
imageView.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 5).isActive = true
}
internal func setText(_ text: String, andImage image: String){
infoLabel.text = text
imageView.image = UIImage(named: image)
}
}
and here is how I'm adding it to view -
let aView: CustomView = CustomView(frame: CGRect(x: 20, y: 144, width: 120, height: 31))
view.addSubview(aView)
aView.setText("my testing label", andImage: "distanceIcon")
aView.backgroundColor = UIColor.red
I get the result like added image.(red is my custom view, white is label and gray is image)
Edit: It is working if add view in Storyboard and but if I try via code as mentioned above it is not working.
You have to call translatesAutoresizingMaskIntoConstraints = false on CustomView class instance as well:
self.translatesAutoresizingMaskIntoConstraints = false
Also add leading and top constraints on custom view to set it's position:
customView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: 200).isActive = true
customView.topAnchor.constraint(equalTo: self.view.topAnchor, constant: 200).isActive = true
Don't forget to add trailing constraint on imageView:
imageView.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: -10).isActive = true
