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：

prepareForSegue已更新代码

添加了属性selectedIndex

添加了didSelectRowAtIndexPath活动

在Detail viewcontroller中添加了属性selectedHTMLFileName。

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")

        }
}

从Tableview到Webview Detail的本地文件
