Local files from Tableview to Webview Detail - xcode

Question

I have a UITableView whose each row must take me to a detail page containing UIWebView .At each item (row) of Tableview there is a local HTML file.
With this code, I support the same HTML file:
#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)
}
How to assign to each row the HTML file that matches it?

Answer 1

In my TableViewController :
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
}
}
And in my DetailViewController :
class DetailIntroViewController: UIViewController {
#IBOutlet weak var webView: UIWebView!
override func viewDidLoad() {
super.viewDidLoad()
let localfilePath = NSBundle.mainBundle().URLForResource(self.selectedHTMLFileName, withExtension: "html")
}
}

Answer 2

Make a property selectedHTMLFileName at this viewcontroller where you loading webview. From previous controller having tableview, handle didSelectRowAtIndexPath and set this property to your filename.
let localfilePath = NSBundle.mainBundle().URLForResource(self.selectedHTMLFileName, withExtension: "html")
EDIT:
Something like this can work.
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)
}
}
and in DetailViewController :
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")
}
}
This code is not tested, but you can check the flow of the process.
Changes made are:
prepareForSegue code updated
Added property selectedIndex
Added didSelectRowAtIndexPath event
Added property selectedHTMLFileName in Detail viewcontroller.
