My wish is to make centered image(left) and next to it(right) the label.
Without setting an image, there was a perfectly centered titleLabel:
btnWhatsapp.titleLabel?.adjustsFontSizeToFitWidth = true
btnWhatsapp.setTitle("WhatsApp", for: .normal)
Then I added this code to add an image:
btnWhatsapp.setImage(UIImage(named: "phoneIcon"), for: .normal)
btnWhatsapp.imageView?.layer.transform = CATransform3DMakeScale(0.5, 0.6, 0.5)
btnWhatsapp.imageView?.contentMode = .scaleAspectFit
, and this iswhat I got then:
, so the title disappeared.
Maybe the problem is that image uses more space than its actual size(the size shouldnt take more widht and height than the icon size). I saw this when changed images background(should be this much grey color):
btnWhatsapp.imageView?.backgroundColor = .gray
I tried to use the imageEdgeInsets but it is very hard to calculate it to fit perfectly on every iPhone.
This is the Attributes inspector of the button:
You can't set title and image at once by default, nor position them as you describe.
If you need to have a UIButton, I'd recommend to make a UIView (or possibly horizontal UIStackView) with UIImage and UILabel inside, position them with autolayout, then you can add this view to the UIButton as a subview.
let button = UIButton(type: .custom)
button.frame = viewFrame // This is the desired frame of your custom UIView or UIStackView
button.addSubview(customView)
You will be able to position the views easily for all sizes with this approach, but you will probably want to use autolayout in real word app, instead of hardcoded frames.
Example:
override func viewDidLoad() {
super.viewDidLoad()
let image = UIImageView(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
let label = UILabel(frame: CGRect(x: 0, y: 0, width: 50, height: 50))
label.text = "text"
let stack = UIStackView(arrangedSubviews: [image, label])
stack.frame = CGRect(x: 0, y: 0, width: 100, height: 50)
stack.distribution = .fillEqually
let button = UIButton()
button.frame = CGRect(x: 0, y: 0, width: 100, height: 50)
button.addSubview(stack)
view.addSubview(button)
self.view.addSubview(button)
}
Set your button under your controller class like this:
let imageButton: UIButton = {
let b = UIButton(type: .custom)
b.backgroundColor = #colorLiteral(red: 0.3411764801, green: 0.6235294342, blue: 0.1686274558, alpha: 1)
b.layer.cornerRadius = 12
b.clipsToBounds = true
b.translatesAutoresizingMaskIntoConstraints = false
let imageV = UIImageView()
imageV.image = UIImage(named: "yourImage")?.withRenderingMode(.alwaysTemplate)
imageV.tintColor = .white
imageV.contentMode = .scaleAspectFill
imageV.translatesAutoresizingMaskIntoConstraints = false
imageV.widthAnchor.constraint(equalToConstant: 30).isActive = true
let label = UILabel()
label.text = "WhatsApp"
label.textColor = .white
label.font = .systemFont(ofSize: 16, weight: .regular)
let stack = UIStackView(arrangedSubviews: [imageV, label])
stack.distribution = .fill
stack.spacing = 4
stack.axis = .horizontal
stack.translatesAutoresizingMaskIntoConstraints = false
b.addSubview(stack)
stack.heightAnchor.constraint(equalToConstant: 30).isActive = true
stack.widthAnchor.constraint(equalToConstant: 120).isActive = true
stack.centerXAnchor.constraint(equalTo: b.centerXAnchor).isActive = true
stack.centerYAnchor.constraint(equalTo: b.centerYAnchor).isActive = true
return b
}()
Now in viewDidLoad add button and set constraints in your view (in my case on top)
view.addSubview(imageButton)
imageButton.topAnchor.constraint(equalTo: view.safeAreaLayoutGuide.topAnchor, constant: 20).isActive = true
imageButton.heightAnchor.constraint(equalToConstant: 50).isActive = true
imageButton.widthAnchor.constraint(equalToConstant: 200).isActive = true
imageButton.centerXAnchor.constraint(equalTo: view.centerXAnchor).isActive = true
This is the result:
Problem
I am trying to do everything programmatically, so I have created this ResultController. For some reason, two of my buttons work but the other three don't work. The program doesn't even notice the touch-up event. I have read many posts on this topic but none of the solutions worked for me.
The two buttons that work are the language button and the swap button, which are embedded in a stack view towards the top of the screen. The 3 buttons that don't work are the soundButton, loopButton, and addFlashcardButton on the result card shown in the image below.
Question
What do I need to do such that these buttons respond to touch events?
Here is the code for this viewController, as well as a picture of the result. I will post the important parts and the whole code for reference. The Buttons are laid out in two functions, setupResultsView() and setupScrollView():

I am stuck in UIButton. I want to add to UIButton text and then next to text add an image, like this:
I want to center it.
when I type this:
let button = UIButton(type: .custom)
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle("Přidat za: \(priceForCategory)", for: .normal)
button.setImage(UIImage(named: "Coin"), for: .normal)
button.imageEdgeInsets = UIEdgeInsets(top: 6, left: -100, bottom: 6, right: 6)
button.titleLabel?.textAlignment = .right
button.alignImageRight()
button.imageView?.contentMode = .scaleAspectFit
button.backgroundColor = UIColor.custom.orange
button.addTarget(self, action: #selector(handleAddCategory), for: .touchUpInside)
button.tintColor = .white
button.titleLabel?.font = UIFont(name: ".SFUIText-Bold", size: 20)
It shows me:
My height breaks and still it doesn't work.
button.alignImageRight()
Means
func alignImageRight() {
if UIApplication.shared.userInterfaceLayoutDirection == .leftToRight {
semanticContentAttribute = .forceRightToLeft
}
else {
semanticContentAttribute = .forceLeftToRight
}
}
Thanks for every answer.
Create func for adding UIButton
func addRoundedButton() {
let button = UIButton(type: .custom)
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle("Add for: 100", for: .normal)
button.setImage(UIImage(named: "Coin"), for: .normal)
button.alignImageRight()
//Add this line for rounded corner
button.layer.cornerRadius = 20 // set cornerRadius = height/2
button.backgroundColor = UIColor.orange
button.tintColor = .white
button.titleLabel?.font = UIFont(name: ".SFUIText-Bold", size: 20)
view.addSubview(button)
[button.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: -15),
button.centerXAnchor.constraint(equalTo: view.centerXAnchor),
button.heightAnchor.constraint(equalToConstant: 40),
button.widthAnchor.constraint(equalToConstant: 300)].forEach{ $0.isActive = true }
}
Create extension for UIButton (as you already created). but add UIEdgeInsets in extension.
extension UIButton {
func alignImageRight() {
if UIApplication.shared.userInterfaceLayoutDirection == .leftToRight {
semanticContentAttribute = .forceRightToLeft
imageEdgeInsets = UIEdgeInsets(top: 0, left: 15, bottom: 0, right: 0)
} else {
semanticContentAttribute = .forceLeftToRight
imageEdgeInsets = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 15)
}
}
}
Output
TIP
For auto adjust width depend on Text and Image, use this extension
How can i display the UIButton titleLabel text to bottom of its frame. Currently i am using the UIEdge top margin and setting the negative UIButton image width, result is not as expected. i also want to place the image center to its frame.
`
let leftButton: UIButton = {
let button = UIButton()
button.layer.borderWidth = 2
button.layer.borderColor = UIColor.ublGray1().cgColor
button.setImage(UIImage.init(named: leftButtonImage)?.withRenderingMode(.alwaysTemplate), for: .normal)
button.tintColor = UIColor.cerulean()
button.layer.masksToBounds = false
button.layer.cornerRadius = 37
button.translatesAutoresizingMaskIntoConstraints = false
button.setTitle(leftButtonTitle, for: .normal)
button.titleEdgeInsets = UIEdgeInsets(top: 110, left: -26, bottom: 0, right: 0)[![enter image description here][1]][1]
button.imageEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0)
button.setTitleColor(UIColor.charcoalGrey(), for: .normal)
button.titleLabel?.font = UIFont.aspiraMedium(size: 16)
return button
}()
`
You can try something like this.
How about setting "Title Insets" - bottom - to a negative number? It works.
But if you want it to stick to the bottom of the frame, it won't work, so... how about this:
bt.titleEdgeInsets.top = (bt.imageView?.safeAreaInsets.bottom)!
or bt.titleEdgeInsets.top = (bt.imageView?.alignmentRectInsets.bottom)!
