Ios UIN航空标题颜色更改问题

当我弹出控制器时，我面对的导航标题颜色没有改变。请查找下面的代码

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
    }

编辑：vc.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)
    }

我有一个标题的颜色变化面临的问题，请检查以下更好的理解

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
    }

而在VC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

这似乎是一个棘手的问题，导航栏的标题属性仅通过向前应用

在尽我所能尝试之后，我决定采用以下解决方法，在navigationItem中提供我自己的标题视图

    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中提供标题，以便在向前导航时正确设置“后退”按钮。
