从Tableview到Webview Detail的本地文件

Question

我有一个UITableView，每行必须带我到一个包含UIWebView的详细页面。Tableview的每个项目（行）都有一个本地HTML文件。 使用此代码，我支持相同的HTML文件：

@IBOutlet weak var webView: UIWebView!

override func viewDidLoad() {
    super.viewDidLoad()
    let localfilePath = NSBundle.mainBundle().URLForResource("yyy", withExtension: "html")
    let myRequest = NSURLRequest(URL: localfilePath!)
    webView.loadRequest(myRequest)
}

如何为每一行分配与之匹配的HTML文件？

Answer 1

在此加载webview的viewcontroller中创建一个属性selectedHTMLFileName。从具有tableview的先前控制器，处理didSelectRowAtIndexPath并将此属性设置为您的文件名。

let localfilePath = NSBundle.mainBundle().URLForResource(self.selectedHTMLFileName, withExtension: "html")

修改

这样的事情可以奏效。

class IntroTableViewController: UITableViewController {
    var labelintro = [String]()
    var webAddresses = [String]()
    int selectedIndex = 0;

override func viewDidLoad() {
    super.viewDidLoad()

    labelintro = ["Avant-propos", "Zone Sakalava", "Pronontiation", "Conjugaison", "Verbes indispensables","Grammaire & synthaxe","Mots indispensables","Les comptes","Le temps", "Termes de politesse", "La famille", "Se déplacer", "Le commerces", "Les vêtements", "Se loger", "Nourritures, épices & condiments", "Nature & paysages", "Ville, village", "L'école", "La flore", "La faune", "Santé & corps", "Artisanat, tradition & sacré", "Expressions courantes"]


    webAddresses = ["xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html"]

}

override func prepareForSegue(segue: UIStoryboardSegue,
                              sender: AnyObject?) {

    if segue.identifier == "gotodetail" {
        var detailIntroVC = segue!.destinationViewController as DetailIntroViewController;
        detailIntroVC.selectedHTMLFileName = webAddresses[selectedIndex];
    }
}

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

// MARK: - Table view data source

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Incomplete implementation, return the number of sections
    return 1
}

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


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


    let row = indexPath.row
    cell.labelIntro.text = labelintro[row]

    return cell
}

override func tableView(_ tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

 selectedIndex = indexPath.row;
 self.performSegueWithIdentifier("gotodetail", sender: self)

   }

}

并在DetailViewController中：

class DetailIntroViewController: UIViewController {


string selectedHTMLFileName;
@IBOutlet weak var webView: UIWebView!


override func viewDidLoad() {
    super.viewDidLoad()

    // Use filename without extension
    var fileNameComponents = split(selectedHTMLFileName) {$0 == "."}
    selectedHTMLFileName = fileNameComponents[0]

    let localfilePath = NSBundle.mainBundle().URLForResource(selectedHTMLFileName, withExtension: "html")

    }
}

此代码未经过测试，但您可以检查流程的流程。

所做的更改是：

1. prepareForSegue已更新代码
2. 添加了属性selectedIndex
3. 添加了didSelectRowAtIndexPath活动
4. 在Detail viewcontroller中添加了属性selectedHTMLFileName。

Answer 2

在我的TableViewController中：

    class IntroTableViewController: UITableViewController {
        var labelintro = [String]()
        var webAddresses = [String]()

    override func viewDidLoad() {
        super.viewDidLoad()

        labelintro = ["Avant-propos", "Zone Sakalava", "Pronontiation", "Conjugaison", "Verbes indispensables","Grammaire & synthaxe","Mots indispensables","Les comptes","Le temps", "Termes de politesse", "La famille", "Se déplacer", "Le commerces", "Les vêtements", "Se loger", "Nourritures, épices & condiments", "Nature & paysages", "Ville, village", "L'école", "La flore", "La faune", "Santé & corps", "Artisanat, tradition & sacré", "Expressions courantes"]


        webAddresses = ["xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html","xxx.html", "yyy.html"]

    }

    override func prepareForSegue(segue: UIStoryboardSegue,
                                  sender: AnyObject?) {

        if segue.identifier == "gotodetail" {
            _ = segue.destinationViewController
                as! DetailIntroViewController
        }
    }

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

    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

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


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


        let row = indexPath.row
        cell.labelIntro.text = labelintro[row]

        return cell
    }

}

在我的DetailViewController中：

    class DetailIntroViewController: UIViewController {



    @IBOutlet weak var webView: UIWebView!


    override func viewDidLoad() {
        super.viewDidLoad()


        let localfilePath = NSBundle.mainBundle().URLForResource(self.selectedHTMLFileName, withExtension: "html")

        }
}
