ios - 如何在iOS的Google Material Design上禁用水平滚动到选项卡

我不知道如何从googlematerialdesignforios中禁用标签栏的水平滚动。我打算做一个固定的标签栏，有3个标签选项。
也许有人能帮我。提前谢谢你。
示例代码：

import UIKit
import MaterialComponents
import ChameleonFramework

class ViewController: UIViewController, MDCTabBarDelegate {


  override func viewDidLoad() {
    super.viewDidLoad()
    view.backgroundColor = .white
    navigationController?.navigationBar.isTranslucent = false
    setupView()
  }

  let tabBarContainer: MDCTabBar = {

    let tabBar = MDCTabBar()

    tabBar.barTintColor = .white

    tabBar.items = [
      UITabBarItem(title: "All Activities", image: nil, tag: 0),
      UITabBarItem(title: "Bookmark", image: nil, tag: 0),
      UITabBarItem(title: "My Journal", image: nil, tag: 0)
    ]

    tabBar.itemAppearance = .titledImages
    tabBar.autoresizingMask = [.flexibleWidth, .flexibleBottomMargin]
    tabBar.sizeToFit()

    tabBar.tintColor = UIColor.rgb(red: 12, green: 82, blue: 143)
    tabBar.selectedItemTintColor = UIColor.rgb(red: 12, green: 82, blue: 143)
    tabBar.unselectedItemTintColor = .lightGray

    return tabBar
  }()

  func setupView() {
    view.addSubview(tabBarContainer)
    view.addConstraintsWithFormat("H:|[v0]|", views: tabBarContainer)
    view.addConstraintsWithFormat("V:|[v0(48)]", views: tabBarContainer)
  }
}

Actual sample of the issue on simulator

最佳答案

也许我迟到了，但我可以通过

tabBar.alignment = .justified
