i have a stackview with an imageview and a label underneath it but when i try to add it into stackview it doesnt appear and apparently all the constraints break.i want the imageview to be fixed width and height and the stackview to equal the width of the label
let userView_stackView = UIStackView()
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
userView_stackView.axis = .vertical
userView_stackView.alignment = .center
userView_stackView.spacing = 5
userView_stackView.addArrangedSubview(user_imageView)
userView_stackView.addArrangedSubview(user_name)
self.contentView.addSubview(userView_stackView)
stackView_constraints()
}
var user_imageView: UIImageView = {
let imageView = UIImageView()
let imageViewHeightAndWidth: CGFloat = 60
let image = UIImage(named: "steve")
imageView.image = image
imageView.layer.borderWidth = 1
imageView.clipsToBounds = true
imageView.layer.borderColor = UIColor.white.cgColor
imageView.layer.cornerRadius = imageViewHeightAndWidth / 2
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.heightAnchor.constraint(equalToConstant: imageViewHeightAndWidth).isActive = true
imageView.widthAnchor.constraint(equalToConstant: imageViewHeightAndWidth).isActive = true
return imageView
}()
var user_name: UILabel = {
let label = UILabel()
label.text = "Steve Rodriquez"
label.font = label.font.withSize(14)
return label
}()
func stackView_constraints() {
userView_stackView.topAnchor.constraint(equalTo: self.contentView.topAnchor, constant: 0).isActive =
true
userView_stackView.leadingAnchor.constraint(equalTo: self.contentView.leadingAnchor, constant: 0)
.isActive = true
userView_stackView.trailingAnchor.constraint(
equalTo: self.contentView.trailingAnchor, constant: 0
).isActive = true
userView_stackView.bottomAnchor.constraint(equalTo: self.contentView.bottomAnchor, constant: 0)
.isActive = true
}
Adding views like this breaks the constraints and prints the following error on the console where all the constraints are breaking
[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
