javascript - NSStatusBar 与 NodObjC

Question

我正在尝试使用 NodObjC 使用 Node.js 创建一个可可应用程序。我一直在创建一个仅在 MacOS X 上作为 HTTP 服务器运行的应用程序。

NodObjC https://github.com/TooTallNate/NodObjC

我想像这样在 StatusBar 上用图标显示服务器状态。

我试过这样：

var $ = require('NodObjC');
$.import('Foundation');
$.import('Cocoa');

var systemStatusBar = $.NSStatusBar('systemStatusBar');
var _statusItem = systemStatusBar('statusItemWithLength', $.NSVariableStatusItemLength);
_statusItem('setHighlightMode', 'YES');
var title = $.NSString('stringWithUTF8String', 'Test');
_statusItem('setTitle', title);
_statusItem('setMenu', systemStatusBar);

但是这段代码会导致错误

node[15637:707] -[NSStatusItem _setMenuOwner:]: unrecognized selector sent to instance 0x10816d810

tmp/node_modules/NodObjC/lib/id.js:158
    throw e
          ^

    at Object.<anonymous> (tmp/test.js:30:1)
    at Module._compile (module.js:456:26)

我找不到此错误的任何解决方案。有人可以给我任何建议吗？

Answer 1

我终于想出了如何自己做到这一点。

var $ = require('NodObjC')
$.import('Cocoa')

var pool = $.NSAutoreleasePool('alloc')('init'),
    app  = $.NSApplication('sharedApplication'),
    statusMenu;



// set up the app delegate
var AppDelegate = $.NSObject.extend('AppDelegate')
AppDelegate.addMethod('applicationDidFinishLaunching:', 'v@:@', function (self, _cmd, notif) {
  var systemStatusBar = $.NSStatusBar('systemStatusBar');
  statusMenu = systemStatusBar('statusItemWithLength', $.NSVariableStatusItemLength);
  statusMenu('retain');
  var title = $.NSString('stringWithUTF8String', "Hello World");
  statusMenu('setTitle', title);
})
AppDelegate.register()

var delegate = AppDelegate('alloc')('init')
app('setDelegate', delegate)

app('activateIgnoringOtherApps', true)
app('run')

pool('release');
