我已经从 Apple 下载了 TVMLCatalog 应用程序。代码分为两部分。

  1. 客户端- 这包含 TVML 和 TVJS 文件
  2. TVMLCatalog 项目- 这是设置 TVML/TVJS 的基本 Xcode 项目

我正在尝试将客户端TVJS 文件托管在与TVMLCatalog Project相同的捆绑包中。

我已将 AppDelegate didFinishLaunching 更改如下：

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.
    */

    TVBootURL = NSBundle.mainBundle().pathForResource("application", ofType: "js")!
    TVBaseURL = TVBootURL.stringByReplacingOccurrencesOfString("application.js", withString: "")
    if let javaScriptURL = NSURL(string: TVBootURL) {
        appControllerContext.javaScriptApplicationURL = javaScriptURL
    }

    appControllerContext.launchOptions["BASEURL"] = TVBaseURL

    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
}

这是演示我如何导入客户端的屏幕截图： Xcode Screenshot

当我运行项目（仅在模拟器上测试）时，AppleTV 模拟器屏幕上显示以下消息：

启动应用程序时出错 - 操作无法完成。（TVMLKitErrorDomain 错误 3。）

我可以像这样从本地的 TVJS 文件加载吗？

经过一番深入的谷歌搜索后，我能够找到答案。这个人的帖子真的帮助了我：

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

该示例在objective-c 中，但我已经实现了一个Swift 解决方案。

这是我从原始帖子更改代码的方式：

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
}

一个重要提示：您需要更改 TVJS 文件中的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`
];
...

这条路：

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

变成：

${options.BASEURL}Index.xml.js

重要提示：将您的 application.js 文件添加到项目的目标中；启动新项目时默认不添加此项。

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
}
