在带有indexPath.row的tableView中从Dictionary获取值？

Question

I'm trying to get info from a plist. Here's the struct :

Root
-Dictionary
--Dictionary
---String
---String
--Dictionary
---String
---String
--Dictionary
---String
---String

edit : And a little sample of it :

<plist version="1.0">
<dict>
    <key>introduction</key>
    <dict>
        <key>gfx</key>
        <dict>
            <key>titre</key>
            <string>Introduction</string>
            <key>color</key>
            <string></string>
            <key>miniLogo</key>
            <string></string>
            <key>bigLogo</key>
            <string></string>
        </dict>
...

So basically I'm to get the string value from a dictionary nested in another dictionary.

The trick is, I want to use a tableView

So far I'm here :

let pathRoot = NSBundle.mainBundle().pathForResource("MyPLIST", ofType: "plist")

let rootRubrique = NSDictionary(contentsOfFile: pathRoot!)

I'm trying to get the info like that :

let rubriqueTitre = NSDictionary(contentsOfFile: pathRoot!)?.allKeys[indexPath.row].objectForKey("gfx")?.valueForKey("titre")

But maybe the problem is from the way I'm trying to screen that

label.text = imageRubrique! as! String
// And also tried :
label.text = "\(imageRubrique!)"

Also I tried to get other values, just to try. This is working for me :

let rubriqueIndex = NSDictionary(contentsOfFile: pathRoot!)?.allKeys[indexPath.row]
 label.text = rubriqueIndex as! String

I get the "introduction" with a lower case, the first one. But I don't want that value, I want the nested one ! I'm getting crazy! Fortunately for me Stackoverflow exist!

After that, I'll have to find a way to sort my dictionary in the right order which seems to be another big problem…

edit : I solved the first issue like that. I've created this func :

func getValueFromPLIST(rub: String, sousDossier : String, sousSousDossier : String?, value : String) -> String {

if sousSousDossier == nil {

    return (NSDictionary(contentsOfFile: pathRoot!)!.objectForKey(rub)!.objectForKey(sousDossier)!.valueForKey(value) as? String)!
} else {

    return (NSDictionary(contentsOfFile: pathRoot!)!.objectForKey(rub)!.objectForKey(sousDossier)!.objectForKey((sousSousDossier!))!.valueForKey(value) as? String)!
}

}

then I'm assigning the index to a constant :

let rubriqueIndex = NSDictionary(contentsOfFile: pathRoot!)?.allKeys[indexPath.row]

And then I'm generating the whole valueForKey via the func :

let rubriquePathTitre = getValueFromPLIST(String(rubriqueIndex!), sousDossier: "gfx", sousSousDossier: nil, value: "titre")

I have no idea why it's working with that trick, but it's working, and it's not so bad since I need the index somewhere else. But unfortunately I think I'm gonna have to use something else, like a "rank" or "ID" value to sort my dictionary. So the whole thing is useless in the end haha!

Answer 1

You can use UITableView index instead iteration index

// *** Access data from plist ***
let pathRoot = NSBundle.mainBundle().pathForResource("MyPLIST", ofType: "plist")

// *** Get Root element of plist ***
let rootRubrique = NSDictionary(contentsOfFile: pathRoot!)

// *** get Next element which is `Introduction` holding all other objects ***
let objIntro:NSDictionary = rootRubrique!.objectForKey("introduction") as! NSDictionary

Option 1 : Iterate Through all objects using Index

for var i = 1; i <= objIntro.allValues.count; ++i
{
    print("Index[\(i)] \(objIntro.allValues[0])")
}    

Access Using indexpath in your case

let obj = (objIntro.allValues[indexPath.row])

Option 2 : Iterate through allValues of dictionary

for (key, value) in objIntro
{
    print("key: \"\(key as! String)\" obj : \(value)")
}
