Hi everyone,
ran into this problem:
there is a table view; it has a header view.
header view has 2 buttons
one button (expandButton) is clickable and the other (closeButton) is not
please help me figure it out
private(set) lazy var expandButton: UIButton = {
let button = UIButton()
button.setTitleStyled(buttonLabelText, fontName: Constants.robotoMediumFont, fontSize: appearance.expandButtonLabelSize, fontColor: appearance.textColor)
button.addTarget(self, action: #selector(expandLabel), for: .touchUpInside)
return button
}()
private(set) lazy var closeButton: UIButton = {
let button = UIButton()
button.translatesAutoresizingMaskIntoConstraints = false
button.setImage(UIImage(named: "24_x_24_close"), for: .normal)
button.addTarget(self, action: #selector(closeButtonTapped), for: UIControl.Event.touchUpInside)
return button
}()
@objc func expandLabel() {
print("Done")
let params: [AnyHashable : Any] = ["installationId": Constants.deviceUniqueId as Any, "product": product?.code as Any]
appMetricaFactory = factory.makeAppMetricaFactory()
appMetricaFactory?.sendRequest(name: "productShowMoreDescription", parametrs: params)
if CardConst.expandedState == .collapsed {
CardConst.expandedState = .expanded
} else {
CardConst.expandedState = .collapsed
}
ProductCardViewController.shared?.updateView()
}
@objc func closeButtonTapped(_ sender: UIButton) {
print("Tapped")
ProductCardViewController.shared?.customizeView()
onClose?()
}

When the application is launched, the compiler gives out this information : (When the application is launched, the compiler gives out this information (2020-07-29 13:42:26.411510+0300 News App[1538:86650] [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.

)
Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.), I cannot figure out what I am doing wrong, I have arranged all the constraints
