雨燕側欄菜單中的規定，但沒有出現

Question

我一直在這個指南[https://www.youtube.com/watch?v=qaLiZgUK2T0]爲創建一個快捷工具欄菜單中的以下內容：代碼編譯，用了錯誤的......我一定在簡單的東西... 。菜單沒有出現。請協助我找出這個問題。

ViewController.swift：

爲菜單中的代碼在三個文件下面列出

import UIKit 
class ViewController: UIViewController, SideBarDelegate { 

var sideBar:SideBar = SideBar() 

override func viewDidLoad() { 
    super.viewDidLoad() 

    sideBar = SideBar(sourceView: self.view, menuItems: ["first item","second item","third item"]) 

} 

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

func sideBarDidSelectButtonAtIndex(index: Int) { 

}  
}   

SideBarTableViewController.swift：

import UIKit 

protocol SideBarTableViewControllerDelegate{ 
func sideBarControlDidSelectRow(indexPath:NSIndexPath); 
} 

class SideBarTableViewController: UITableViewController { 

var delegate:SideBarTableViewControllerDelegate? 
var tableData:Array<String> = [] 


override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 
    return 1 
} 

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 
    return tableData.count; 
} 

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
    var cell:UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell 

    if cell == nil{ 
     cell = UITableViewCell(style :UITableViewCellStyle.Default, reuseIdentifier: "Cell") 
     // Configure the cell... 
     cell!.backgroundColor = UIColor.clearColor() 
     cell!.textLabel.textColor = UIColor.darkTextColor() 

     let selectedView:UIView = UIView(frame: CGRect (x: 0, y:0, width: cell!.frame.size.width, height: cell!.frame.size.height)) 
     selectedView.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.3) 

     cell!.selectedBackgroundView = selectedView 

    } 

    cell!.textLabel.text = tableData[indexPath.row] 

    return cell! 
} 

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat{ 
    return 45.0 
} 

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
    delegate?.sideBarControlDidSelectRow(indexPath) 
} 

} 

SideBar.swift

import UIKit 

@objc protocol SideBarDelegate{ 
    func sideBarDidSelectButtonAtIndex(index:Int) 
    optional func sideBarWillClose() 
    optional func sideBarWillOpen()

    sideBarTableViewController.tableData = menuItems 

    animator = UIDynamicAnimator(referenceView: orginView) 

    let showGestureRecognizer:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "handleSwipe:") 
    showGestureRecognizer.direction = UISwipeGestureRecognizerDirection.Right 
    orginView.addGestureRecognizer(showGestureRecognizer) 

    let hideGesturerecognizer:UISwipeGestureRecognizer = UISwipeGestureRecognizer(target: self, action: "handleSwipe:") 
    hideGesturerecognizer.direction = UISwipeGestureRecognizerDirection.Left 
    orginView.addGestureRecognizer(hideGesturerecognizer) 

} 

func setupSideBar(){ 
    sideBarContainerView.frame = CGRectMake(-barWidth - 1,orginView.frame.origin.y, barWidth, orginView.frame.size.height) 
    sideBarContainerView.backgroundColor = UIColor.clearColor()

} 

func sideBarControlDidSelectRow(indexPath: NSIndexPath) { 
    delegate?.sideBarDidSelectButtonAtIndex(indexPath.row) 
} 
}

當我下載源代碼時，我經歷並調試了項目文件，我必須做的所有工作是對SideBarTableViewController.swift進行一些小改動，並且所有工作都適用於我。這是它：

import UIKit 


protocol SideBarTableViewControllerDelegate{ 
    func sideBarControlDidSelectRow(indexPath:NSIndexPath) 
} 

class SideBarTableViewController: UITableViewController { 

    var delegate:SideBarTableViewControllerDelegate? 
    var tableData:Array<String> = [] 


    // MARK: - Table view data source 

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int { 

     return 1 
    } 

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int { 

     return tableData.count 
    } 

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { 
     var cell = tableView.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell 

     if cell == nil{ 
      cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell") 
      // Configure the cell... 

      cell?.backgroundColor = UIColor.clearColor() 
      cell?.textLabel?.textColor = UIColor.darkTextColor() 

      let selectedView:UIView = UIView(frame: CGRect(x: 0, y: 0, width: cell!.frame.size.width, height: cell!.frame.size.height)) 
      selectedView.backgroundColor = UIColor.blackColor().colorWithAlphaComponent(0.3) 

      cell!.selectedBackgroundView = selectedView 
     } 
     cell?.textLabel?.text = tableData[indexPath.row] 
     return cell! 

    } 

    override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat { 
     return 45.0 
    } 

    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) { 
     delegate?.sideBarControlDidSelectRow(indexPath) 

    } 

}
