Adding UIButton to toolbar swift 5 - ios

Question

so I have read other stack overflow ages and none seem to help me. I have a piece of code that creates my UIButton which is here:
let haveAccountButton: UIButton = {
let HColor = UIColor(red: 89/255, green: 156/255, blue: 120/255, alpha: 1)
let HFont = UIFont.systemFont(ofSize: 16)
let HSColor = UIColor(red: 239/255, green: 47/255, blue: 102/255, alpha: 1)
let HButton = UIButton(type: .system)
let attributedTitle = NSMutableAttributedString(string:
NSLocalizedString("Already have an account?", comment: ""), attributes: [NSAttributedString.Key.foregroundColor: UIColor.lightGray, NSAttributedString.Key.font: HFont])
attributedTitle.append(NSAttributedString(string: NSLocalizedString(" Sign In", comment: ""), attributes: [NSAttributedString.Key.foregroundColor: HSColor, NSAttributedString.Key.font: HFont]))
HButton.addTarget(self, action: #selector(signinAction), for: .touchUpInside)
HButton.setAttributedTitle(attributedTitle, for: .normal)
return HButton
}()
I already set navigationController?.isToolbarHidden = false in viewDidLoad. my question is how do I make the button appear in the toolbar?
UPDATE: The way this code will run currently without the toolbar is as follows:
import Foundation
import UIKit
class SignUpControllerSave: UIViewController {
let haveAccountButton: UIButton = {
let HColor = UIColor(red: 89/255, green: 156/255, blue: 120/255, alpha: 1)
let HFont = UIFont.systemFont(ofSize: 16)
let HSColor = UIColor(red: 239/255, green: 47/255, blue: 102/255, alpha: 1)
let HButton = UIButton(type: .system)
let attributedTitle = NSMutableAttributedString(string:
NSLocalizedString("Already have an account?", comment: ""), attributes: [NSAttributedString.Key.foregroundColor: UIColor.lightGray, NSAttributedString.Key.font: HFont])
attributedTitle.append(NSAttributedString(string: NSLocalizedString(" Sign In", comment: ""), attributes: [NSAttributedString.Key.foregroundColor: HSColor, NSAttributedString.Key.font: HFont]))
HButton.addTarget(self, action: #selector(signinAction), for: .touchUpInside)
HButton.setAttributedTitle(attributedTitle, for: .normal)
return HButton
}()
//potential gradient background if wanted
func setGradientBackground() {
let top_Color = UIColor(red: 203/255, green: 215/255, blue: 242/255, alpha: 1.0).cgColor
let bottom_Color = UIColor(red: 181/255, green: 199/255, blue: 242/255, alpha: 1.0).cgColor
let gradientLayer = CAGradientLayer()
gradientLayer.colors = [top_Color, bottom_Color]
gradientLayer.locations = [0, 1]
gradientLayer.frame = self.view.bounds
self.view.layer.insertSublayer(gradientLayer, at: 0)
}
override func viewDidLoad() {
super.viewDidLoad()
//view.backgroundColor = .yellow
navigationController?.isNavigationBarHidden = true
navigationController?.isToolbarHidden = false
navigationItem.title = NSLocalizedString("Membership", comment: "")
setupHaveAccountButton()
}
override func viewWillAppear(_ animated: Bool) {
navigationController?.isNavigationBarHidden = true
navigationController?.isToolbarHidden = false
setGradientBackground()
super.viewWillAppear(animated)
}
#objc func signinAction() {
navigationController?.popViewController(animated: true)
}
fileprivate func setupHaveAccountButton() {
view.addSubview(haveAccountButton)
haveAccountButton.anchors(top: nil, topPad: 0, bottom: view.safeAreaLayoutGuide.bottomAnchor,
bottomPad: 8, left: view.leftAnchor, leftPad: 0, right: view.rightAnchor,
rightPad: 0, height: 20, width: 0)
}
}
UPDATE: The previous answer did allow for the button to now be on the toolbar, but the button target action does not work. I have tried adding .sizeToFit() where I can and looked at a lot of websites all to no avail. Anyone know how I can go about solving the button target issue?

Answer 1

This code should work the way you want:
class SignUpControllerSave: UIViewController {
/* the other code you posted can be used without changes */
fileprivate func setupHaveAccountButton() {
toolbarItems = [
UIBarButtonItem(customView: haveAccountButton)
]
}
}
As this seems to cause problems with regards to the click handler, try this (which looks almost the same – except for the font size):
class SignUpControllerSave: UIViewController {
fileprivate func setupHaveAccountButton() {
let haveAccountLabel = UILabel()
haveAccountLabel.font = UIFont.systemFont(ofSize: UIFont.buttonFontSize)
haveAccountLabel.text = NSLocalizedString("Already have an account?", comment: "")
haveAccountLabel.textColor = .lightGray
toolbarItems = [
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil),
UIBarButtonItem(customView: haveAccountLabel),
UIBarButtonItem(title: "Sign In", style: .plain, target: self, action: #selector(self.signinAction)),
UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
]
navigationController?.toolbar.tintColor = UIColor(red: 239/255, green: 47/255, blue: 102/255, alpha: 1)
}
}
