Question

我正在创建一个聊天应用程序，其中有一些预定义的常见问题解答，其中包含不同的类别，当用户点击按钮以下是图片的外观：

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。滚动uitableview不起作用。此外，免费和商业部分的数据也会被加载。

以下是ChatViewController类代码，它是上图中显示的父类：

    var categoryName:String = ""

    var categoryQuestion:[String] = []

    override func viewDidLoad() {

        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

    }


    func setQuestionsCategoryArray(_categoryArray: [String], _questionsDictionary:Dictionary<String,[String]>, _categoryName:String)
    {
        //self.categoryArray = _categoryArray
        self.categoryName = _categoryName
        //self.questionsDictionary = _questionsDictionary

    // MARK: - UITableViewDataSource

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

        {

        }
        else
        {
            categoryQuestion = self.questionsDictionary[self.categoryName]!
            print("categoryQuestion count :: ",categoryQuestion.count)
            return categoryQuestion.count
        }

    }

    // MARK: - UITableViewDelegate

    func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! ChatCellView

        //let repository = self.categoryArray[indexPath.row]
        cell.questionNoLbl.text = String(indexPath.row)
        cell.questionLbl.text = categoryQuestion[indexPath.row]
        //cell.questionLbl.text = repository["name"] as? String
        return cell
    }

    func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        tableView.deselectRowAtIndexPath(indexPath, animated: true)

        /*let detailViewController = storyboard?.instantiateViewControllerWithIdentifier("DetailViewController") as! DetailViewController
        navigationController?.pushViewController(detailViewController, animated: true)*/
    }

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

}

还有uitableview的自定义单元格代码如下：

import UIKit

class ChatCellView: UITableViewCell
{

    @IBOutlet var questionNoLbl: UILabel!
    @IBOutlet var questionLbl: UILabel!


}

Answer 1

在这里，我对项目PagingMenuController进行了更改，并根据需要创建了一个UI。

以下是您可以查看的演示项目！

我做了什么？

我刚刚根据需要将ContainerView的约束更改为特定高度。

并确保您已对其ChildViewController提供了适当的约束。

项目下载链接：https://www.dropbox.com/s/zili4l7yot7dnvo/Example.zip?dl=0

回答更新

如果您使用的是Autolayout，那么您可以使用frame来更改约束，这肯定会导致错误。如果您想要更改，那么您可以通过以下方式完成：

questionViewBottomConstraint.constant = 250.0 //any value (here you can use `UITableView` height)

OR

questionViewBottomConstraint.constant = -250.0

相应地更改约束值并查看差异。

如果有任何改变，请告诉我们！
