您可以在Apple TV而不是外部服务器上托管TVJS文件吗？

经过深层的谷歌搜索，我能够找到答案。这个人的帖子确实对我有帮助：

http://thejustinwalsh.com/objective-c/tvml/2015/09/20/tvml-without-the-webserver.html

该示例在Objective-C中，但我已经实现了Swift解决方案。

这是我从原始帖子中更改代码的方式：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    window = UIWindow(frame: UIScreen.mainScreen().bounds)

    /*
    Create the TVApplicationControllerContext for this application
    and set the properties that will be passed to the `App.onLaunch` function
    in JavaScript.
    */
    let appControllerContext = TVApplicationControllerContext()

    /*
    The JavaScript URL is used to create the JavaScript context for your
    TVMLKit application. Although it is possible to separate your JavaScript
    into separate files, to help reduce the launch time of your application
    we recommend creating minified and compressed version of this resource.
    This will allow for the resource to be retrieved and UI presented to
    the user quickly.
    */

    if let javaScriptURL = NSBundle.mainBundle().URLForResource("application", withExtension: "js"){
        appControllerContext.javaScriptApplicationURL = javaScriptURL
    }

    let TVBaseURL = appControllerContext.javaScriptApplicationURL.URLByDeletingLastPathComponent

    appControllerContext.launchOptions["BASEURL"] = TVBaseURL?.absoluteString

    if let launchOptions = launchOptions as? [String: AnyObject] {
        for (kind, value) in launchOptions {
            appControllerContext.launchOptions[kind] = value
        }
    }

    appController = TVApplicationController(context: appControllerContext, window: window, delegate: self)

    return true
}

重要说明：您需要在TVJS文件中更改文件路径引用，以反映新的包路径结构。

Application.js中的示例：

App.onLaunch = function(options) {
var javascriptFiles = [
    `${options.BASEURL}js/ResourceLoader.js`,
    `${options.BASEURL}js/Presenter.js`
];
...

变成：

App.onLaunch = function(options) {
var javascriptFiles = [
    `${options.BASEURL}ResourceLoader.js`,
    `${options.BASEURL}Presenter.js`
];
...

和这条路：

${options.BASEURL}templates/Index.xml.js

变成：

${options.BASEURL}Index.xml.js

重要提示：将application.js文件添加到项目的目标；启动新项目时，默认情况下不添加此功能。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    // Override point for customization after application launch.
    window = UIWindow(frame: UIScreen.main.bounds)

    // Create the TVApplicationControllerContext for this application and set the properties that will be passed to the `App.onLaunch` function in JavaScript.
    let appControllerContext = TVApplicationControllerContext()

    // The JavaScript URL is used to create the JavaScript context for your TVMLKit application. Although it is possible to separate your JavaScript into separate files, to help reduce the launch time of your application we recommend creating minified and compressed version of this resource. This will allow for the resource to be retrieved and UI presented to the user quickly.
    if let javaScriptURL = Bundle.main.url(forResource: "application", withExtension: "js"){
        appControllerContext.javaScriptApplicationURL = javaScriptURL
    }

    let TVBaseURL = appControllerContext.javaScriptApplicationURL.deletingLastPathComponent()

    appControllerContext.launchOptions["BASEURL"] = TVBaseURL.absoluteString

    if let launchOptions = launchOptions {
        for (kind, value) in launchOptions {
            appControllerContext.launchOptions[kind.rawValue] = value
        }
    }

    appController = TVApplicationController(context: appControllerContext, window: window, delegate: self)

    return true
}
