Question

我想改变所有应用程序的NavigationControl后退按钮的颜色，我该怎么办？我希望用红色代替普通的蓝色按钮......

我的TabBar有问题。我已将图标颜色和名称从标准蓝色更改为红色：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.redColor()], forState:.Selected)

这个

class TabBarController: UITabBarController {

var color = UIColor.redColor()

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any additional setup after loading the view, typically from a nib.
    self.tabBarController?.tabBar.selectedImageTintColor = UIColor.redColor()
    UITabBar.appearance().selectedImageTintColor = UIColor.redColor()

但是我有超过5个标签，所以我有“更多”按钮，当我按下它时，图标不是红色而是蓝色，当我按下编辑标签栏图标时，名称选项卡为红色，但图标不是。我能做什么？图片解释： http://postimg.org/image/67oqa15ll/

Answer 1

在整个应用程序中更改所有UITabBarItem的文本和图标颜色（在Swift / Xcode 6中）：

在AppDelegate.swift中：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // Override point for customization after application launch.

    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: your_color ], forState: .Selected)

    UITabBar.appearance().tintColor = your_color

    return true

}

这就行了！

在firstViewController中尝试这个

class ViewController: UIViewController,UITabBarDelegate, UITabBarControllerDelegate, UINavigationControllerDelegate {

        override func viewDidLoad() {
            super.viewDidLoad()

            UITabBar.appearance().tintColor = UIColor.redColor()
            var view: UITableView = self.tabBarController?.moreNavigationController.topViewController.view as UITableView
            view.tintColor = UIColor.redColor()
            if view.subviews.count != 0 {
                for cell in view.visibleCells() {
                    cell.textLabel??.textColor = UIColor.redColor()
                }
            }
        }

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


}

，这在你的UITabbarController

中

class TabbarViewController: UITabBarController,UITabBarDelegate, UITabBarControllerDelegate, UINavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

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

    override func tabBar(tabBar: UITabBar, didBeginCustomizingItems items: [AnyObject]) {
        self.view.tintColor = UIColor.redColor()

    }
}
