我一直在尝试以下方法,以使导航栏的标题保持左对齐:

在AppDelegate.swift文件中:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    UINavigationBar.appearance().barTintColor = UIColor.red
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:
        UIColor.white]
    return true
}

在TableViewController.swift文件中:

override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        self.navigationController?.navigationBar.topItem?.title = "Home"
    }

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.


    UINavigationBar.appearance().barTintColor = UIColor.red
    UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName:
        UIColor.white]
let lbNavTitle = …
