TVML is a good choice, when you prefer simplicity over dynamic UIKit implementation. TVMLKitchen helps to manage your TVML with or without additional client-server. Put TVML templates in Main Bundle, then you're ready to go.

Loading a TVML view is in this short.

Kitchen.serve(jsFile:"Catalog.xml.js")

Kitchen automatically looks for the jsFile in your Main Bundle, parse and load it, then finally pushes it to navigationController. User can pop to previous viewcontroller with AppleTV(Remote)'s 'Menu' button.

1. Put your Sample.xml.js to your app's main bundle.

2. Prepare your Kitchen in AppDelegate's didFinishLaunchingWithOptions:.

   Kitchen.prepare(launchOptions)
   

3. Launch the template from anywhere.

   Kitchen.serve(jsFile: "Sample.xml.js")
   

4. Got TVML server ? Just pass the URL String and you're good to go.

   Kitchen.serve(urlString: "https://raw.githubusercontent.com/toshi0383/TVMLKitchen/master/SampleRecipe/Catalog.xml.js")

• Inject native code into TVML(javascript) context
• Add error handlers

Kitchen.prepare(launchOptions, evaluateAppJavaScriptInContext:
{ appController, jsContext in
    /// set Exception handler
    /// called on JS error
    jsContext.exceptionHandler = {context, value in
        LOG(context)
        LOG(value)
        assertionFailure("You got JS error. Check your javascript code.")
    }

    /// SeeAlso: http://nshipster.com/javascriptcore/
    /// Inject native code block named 'debug'.
    let consoleLog: @convention(block) String -> Void = { message in
        print(message)
    }
    jsContext.setObject(unsafeBitCast(consoleLog, AnyObject.self),
        forKeyedSubscript: "debug")

}, onError: { error in
    let title = "Error Launching Application"
    let message = error.localizedDescription
    let alertController = UIAlertController(title: title, message: message, preferredStyle:.Alert )

    Kitchen.navigationController.presentViewController(alertController, animated: true) { }

})

Though TVML view cannot be modified programatically after presented(or is there a way?), we can at least generate TVML dynamically by defining Recipe. Theme is customizable.

let banner = "Movie"
let thumbnailUrl = NSBundle.mainBundle().URLForResource("img",
    withExtension: "jpg")!.absoluteString
let actionID = "/title?titleId=1234"
let (width, height) = (250, 376)
let templateURL: String? = nil
let content = ("Star Wars", thumbnailUrl, actionID, templateURL, width, height)
let section1 = Section(title: "Section 1", args: (0...100).map{_ in content})
let catalog = CatalogRecipe<BlackTheme>(banner: banner, sections: (0...10).map{_ in section1})
Kitchen.serve(recipe: catalog)

Note: This feature is still in beta. APIs are subject to change.

• Catalog
• Catalog with select action handler
• Alert with button handler
• Rating with handler
• Compilation with select action handler
• Product with select action handler
• Product Bundle with select action handler
• Stack with select action handler
• Stack Room with select action handler
• Stack Separator with select action handler

and more...

We don't know when or how to inject additional data onto already presented TVML view. For now, if you need 100% dynamic behavior, go ahead and use UIKit.

Put this to your Cartfile,

github "toshi0383/TVMLKitchen"

Follow the instruction in carthage's Getting Started section.

TVML + Native = Hybrid
