  <p>as you can see last tab which is المواجهات المباشرة is not displayed fully..</p>
  
  <p>this is my code:</p>
  
  <pre><code>override func viewDidLoad() {
      super.viewDidLoad()
  
      containerView.isScrollEnabled = false
      containerView.delegate = self
  
      self.settings.style.buttonBarBackgroundColor = UIColor.clear
      self.settings.style.buttonBarItemBackgroundColor = UIColor.clear
      self.settings.style.selectedBarBackgroundColor = UIColor.clear
      self.settings.style.buttonBarItemFont = .boldSystemFont(ofSize: 7)
      self.settings.style.selectedBarHeight = 1.0
      self.settings.style.buttonBarMinimumLineSpacing = 0.1
      self.settings.style.buttonBarItemTitleColor = UIColor.white
      self.settings.style.buttonBarItemsShouldFillAvailableWidth = true
      self.settings.style.buttonBarLeftContentInset = 0
      self.settings.style.buttonBarRightContentInset = 0
      self.settings.style.selectedBarHeight = 1.0
  
      changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -&gt; Void in
          guard changeCurrentIndex == true else { return }
          //oldCell?.label.adjustsFontSizeToFitWidth = true
          //newCell?.label.adjustsFontSizeToFitWidth = true
          oldCell?.label.textColor = UIColor.white
          newCell?.label.textColor = UIColor.white
          oldCell?.label.font = UIFont(name: "AJannatLT", size: 14)!
          newCell?.label.font = UIFont(name: "AJannatLT", size: 14)
          newCell?.label.lineBreakMode = .byCharWrapping
          oldCell?.label.lineBreakMode = .byCharWrapping
          self?.buttonBarView.selectedBar.backgroundColor = UIColor.white
      }
  
      getMatchInfo()
  
      self.navigationController?.navigationBar.topItem?.title = " "
  
      // Do any additional setup after loading the view.
  }
  </code></pre>
