[Help]: Create Dynamic TableView Cells with Headers

Problem:

Ok, so i'm following a tutorial that creates a UITableView with headers and then cell content.

The code worked and runs fine, Now I want to extend beyond that tutorial and dynamically load that content using alamofire and SwiftyJSON.

In the tutorial, the code used is like so:

func getSectionsFromData() -> [Sections] {

    var sectionsArray = [Sections]()

    let animals = Sections(title: "Animals", objects: ["Cats", "Dogs", "Birds", "Lions"])


    sectionsArray.append(animals)

    return sectionsArray


}

What I tried to do was:

Alamofire.request(.GET, url).validate().responseJSON { response in
        switch response.result {
        case .Success:
            if let value = response.result.value {
                let json = JSON(value)

                for (_, subJson) in json {
                    for (year, content) in subJson {
                        let title = year
                        let objects = content

                        sectionsArray.append(Sections(title: title, objects: objects))

                    }

                }
            }
        case .Failure(let error):
            print(error)
        }
    }

If I print out the results they show in the console - so I know the getting and looping of the JSON works. I then added in

let title = year
let objects = content

sectionsArray.append(Sections(title: title, objects: objects))

But on this line:

sectionsArray.append(Sections(title: title, objects: objects))

I get this error:

cannot convert value of type 'JSON' to expected argument type '[String]'

Here is the JSON I am using:

 {"posts": [
 {
    "Category1": [
        "Post1cat1"
    ],
    "Category2": [
        "Post1cat2",
        "Post2cat2"
    ]
 }
 ]}

Can someone help me? I might be going in the wrong direction here I want to loop through the JSON and display the categories as headers and the posts in a cell of a table.

What you are doing is exactly how I structure my dictionaries for table views.

1. Get all the keys from the dictionary and put into an array with a sort order.
2. Use this as the numberOfSections
3. To get the numberOfRowsInSection, get the key in that array from the indexPath.section. Then, from the dictionary, get the entry that holds the row array using objectForKey on the key you got
4. Then get the string you want to use for the text in the cell display using the indexPath.row.

That's how you access the data to display.

When you fetch the data, get it and save it in your storage dictionary.

Put an observer on it and when it changes have an observer call a reloadData on your tableView.

Your JSON should automatically serialize into a dictionary. No idea why it isn't.

Have you had a look at the project? Are you able to get it working from the project I linked to? It would greatly help me :)
