没有故事板或使用 Swift 的 xib 文件的 OSX 应用程序

问题描述

不幸的是，我在 Internet 上没有找到任何有用的东西 - 我想知道，在不使用 Swift 中的情节提要或 XIB 文件的情况下，我实际上必须键入哪些代码来初始化应用程序.我知道我必须有一个名为 main 的 .swift 文件.但我不知道在那里写什么(比如我需要 autoreleasepool 或类似的东西吗?).例如，我将如何初始化 NSMenu 以及如何将 NSViewController 添加到活动窗口(iOS 类似的 .rootViewController 没有)帮助).感谢您的帮助;)

Unfortunately, I haven't found anything useful on the Internet - I wanted to know, what code I actually have to type for initializing an application without using storyboard or XIB files in Swift. I know I have to have a .swift file called main. But I don't know what to write in there (like do I need autoreleasepool or something like that?). For example, what would I do for initializing an NSMenu and how would I add a NSViewController to the active window (iOS's similar .rootViewController doesn't help). Thanks for any help ;)

我实际上不想在 AppDelegate 前面使用 @NSApplicationMain.我宁愿知道那里到底发生了什么，然后自己做.

I actually don't want to use @NSApplicationMain in front of the AppDelegate. I'd rather know what exactly happens there and then do it myself.

推荐答案

如果您不想拥有 @NSApplicationMain 属性，请执行以下操作:

if you don't want to have the @NSApplicationMain attribute, do:

1. 有一个文件 main.swift

1. have a file main.swift

添加以下顶级代码:

 import Cocoa

 let delegate = AppDelegate() //alloc main app's delegate class
 NSApplication.shared.delegate = delegate //set as app's delegate
 NSApplicationMain(CommandLine.argc, CommandLine.unsafeArgv) //start of run loop

 // Old versions:
 //  NSApplicationMain(C_ARGC, C_ARGV)
 //  NSApplicationMain(Process.argc, Process.unsafeArgv);

其余的应该在您的应用程序委托中.例如:

the rest should be inside your app delegate. e.g.:

import Cocoa

class AppDelegate: NSObject, NSApplicationDelegate {
    var newWindow: NSWindow?
    var controller: ViewController?

    func applicationDidFinishLaunching(aNotification: NSNotification) {
        newWindow = NSWindow(contentRect: NSMakeRect(10, 10, 300, 300), styleMask: .resizable, backing: .buffered, defer: false)

        controller = ViewController()
        let content = newWindow!.contentView! as NSView
        let view = controller!.view
        content.addSubview(view)

        newWindow!.makeKeyAndOrderFront(nil)
    }
}

那么你就有了一个视图控制器

then you have a viewController

import Cocoa

class ViewController : NSViewController {
    override func loadView() {
        let view = NSView(frame: NSMakeRect(0,0,100,100))
        view.wantsLayer = true
        view.layer?.borderWidth = 2
        view.layer?.borderColor = NSColor.red.cgColor
        self.view = view
    }
}
