ios - TabBar 显示 9 个项目而不是更多按钮

Question

我有一个 ViewController，它有一个 UITabBar 和一个 webview。触摸选项卡时，webview 加载不同的 URL。我似乎无法弄清楚如何确保显示“更多”按钮而不是在标签栏中压缩 9 个标签。

import UIKit

class HomeViewController: UIViewController, UITabBarDelegate {
@IBOutlet var webView: UIWebView!
@IBOutlet var tabBar: UITabBar!

override func viewDidLoad() {
    super.viewDidLoad()


}

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

override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(true);

    let prefs:NSUserDefaults = NSUserDefaults.standardUserDefaults()
    let isLoggedIn:Int = prefs.integerForKey("ISLOGGEDIN") as Int;
    if (isLoggedIn != 1) {
        self.performSegueWithIdentifier("goto_login", sender: self)
    } else {
        //self.usernameLabel.text = prefs.valueForKey("USERNAME") as NSString
        tabBar.delegate = self;
        tabBar.selectedItem = tabBar.items?.first as UITabBarItem;
        loadPage("http://mywodlog.com");
    }
}

标签栏通常由 UITabBarController 管理。

您的 HomeViewController 是 Root View Controller 吗？将其替换为 UITabBarController。为 WebView 创建一个单独的 View Controller 。
