我正在创建一个聊天应用程序，其中有一些具有不同类别的预定义常见问题解答，当用户单击按钮时会向上滑动。以下是它的外观：

我正在使用以下链接中的 PagingMenucontroller 库： https ://github.com/kitasuke/PagingMenuController
我面临的问题是视图不占用设备的宽度。uitableview 的滚动不起作用。免费的数据和业务部分也只会被加载。
下面是 ChatViewcontroller 类的代码，它是上图所示的父类：

以下是连接到具有表格视图的 xib 的聊天问题视图控制器的代码：

class ChatQuestionsViewController: UIViewController, UITableViewDelegate, UITableViewDataSource
{
@IBOutlet var chatTableView: UITableView!
var categoryArray:[String]!
var categoryName:String = ""
var questionsDictionary:Dictionary<String,[String]> = [:]
var categoryQuestion:[String] = []
override func viewDidLoad() {
super.viewDidLoad()
print("self.chatTableView :: ",chatTableView)
self.chatTableView.registerNib(UINib(nibName: "ChatQuestionCellRowView", bundle: nil), forCellReuseIdentifier: "cell")
self.categoryArray = Constants.questionCategoriesArray
self.questionsDictionary = Constants.questionsDictionary
self.view.autoresizingMask = [UIViewAutoresizing.FlexibleWidth, UIViewAutoresizing.FlexibleHeight]
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code

// MARK: - UITableViewDataSource
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

//let repository = self.categoryArray[indexPath.row]

func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
/*let detailViewController = storyboard?.instantiateViewControllerWithIdentifier("DetailViewController") as! DetailViewController

}
func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {

}
还有 uitableview 的自定义单元格，下面是代码：
import UIKit
class ChatCellView: UITableViewCell
{
@IBOutlet var questionNoLbl: UILabel!
@IBOutlet var questionLbl: UILabel!
}
