【问题描述】：

当我弹出控制器时，我正面临导航标题颜色不变的问题。请找到以下代码。

ProfilescreenVC.swift
override func viewWillAppear(_ animated: Bool) 
        super.viewWillAppear(animated)
        self.navigationController?.navigationBar.tintColor = UIColor.white
        self.navigationController?.navigationBar.barTintColor = UIColor.primaryGreen
        let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
        self.navigationController?.navigationBar.titleTextAttributes = textAttributes
    

EditprofileVC.swift

override func viewDidLoad() 
        super.viewDidLoad()        
        self.style()
    

    override func didReceiveMemoryWarning() 
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    

    func style() 
        navigationController?.navigationBar.tintColor = UIColor.black
        navigationController?.navigationBar.barTintColor = UIColor.white
        let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.black]
        navigationController?.navigationBar.titleTextAttributes = textAttributes

        carbonTabSwipeNavigation.setIndicatorColor(UIColor.black)
        carbonTabSwipeNavigation.setTabBarHeight(50.0)
        carbonTabSwipeNavigation.setNormalColor(UIColor.hexString("9A9CA1"), font: UIFont.systemFont(ofSize: 15))
        carbonTabSwipeNavigation.setSelectedColor(UIColor.black, font: UIFont.systemFont(ofSize: 15))

        self.navigationController?.view.setNeedsLayout()
        self.navigationController?.view.layoutIfNeeded()
    

    override func viewDidDisappear(_ animated: Bool) 
        navigationController?.navigationBar.tintColor = UIColor.white
        navigationController?.navigationBar.barTintColor = UIColor.white
        let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
        navigationController?.navigationBar.titleTextAttributes = textAttributes
        super.viewDidDisappear(animated)

【参考方案1】：

这似乎是一个尴尬的问题，导航栏的标题属性只能通过前进来应用。

在尝试了所有我能做的事情后，我解决了以下解决方法，我在 navigationItem 中提供了自己的 titleView。

    let titleView = UIView(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
    titleView.backgroundColor = UIColor.clear
    let titleLabel = UILabel(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
    titleLabel.textAlignment = .center
    titleLabel.text = "Profile"
    titleLabel.textColor = .white
    titleView.addSubview(titleLabel)
    self.navigationItem.titleView = titleView
    self.navigationItem.title = "Profile"

请注意，您还需要在 navigationItem.title 中提供您的标题，以便在您向前导航时正确设置后退按钮。

【参考方案2】：

ProfilescreenVC.swift

override func viewWillAppear(_ animated: Bool) 

        super.viewWillAppear(animated)
        self.navigationController?.navigationBar.tintColor = UIColor.white
        self.navigationController?.navigationBar.barTintColor = UIColor.primaryGreen
        let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
        self.navigationController?.navigationBar.titleTextAttributes = textAttributes
    

在editProfileVC中

override func viewWillAppear(_ animated: Bool) 
        
    navigationController?.navigationBar.tintColor = UIColor.black
            navigationController?.navigationBar.barTintColor = UIColor.white
            let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.black]
            navigationController?.navigationBar.titleTextAttributes = textAttributes
    

无需在代码中添加ViewDidDisapper
