TabBar显示9个项目而不是更多按钮

Question

我有一个具有UITabBar和webview的ViewController。触摸选项卡时，webview会加载不同的URL。我似乎无法弄清楚如何确保更多按钮显示而不是压缩标签栏中的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是根视图控制器吗？将其替换为UITabBarController。为Web视图创建单独的视图控制器。
