Swift OSX键事件 [英] Swift OSX key event

问题描述

我一直在开发一个Cocoa OSX项目在swift，需要使用键盘输入预制一个动作。在keydown我想移动一个对象在窗口，但停止对象一旦密钥被释放。我已经查看了AppKit的文档，并发现KeyDown函数，但我似乎不知道如何使用它。我想创建一个函数来调用我的游戏更新计时器，这将预先做到这一点。感谢

  import Cocoa 
 import Appkit 
 
 @NSApplicationMain 
 class AppDelegate： NSObject，NSApplicationDelegate {
 
 @IBOutlet弱var窗口：NSWindow！ 
 
 func applicationDidFinishLaunching（aNotification：NSNotification）{
 //在此插入代码以初始化应用程序
 
 func keyDown（theEvent：NSEvent）{
 if （theEvent.keyCode == 1）{
 println（test）
} 
 
} 
 
} 
 
 func applicationWillTerminate（aNotification：NSNotification）{
 //在此插入代码以清除应用程序
 
 
 
} 
  
 
 
 
} 
解决方案
 
  override func keyDown（theEvent：NSEvent）{
 if（theEvent.keyCode == 1）{
 //按下s键时执行任何操作
} 
 
}

I have been working on a Cocoa OSX project in swift that requires the use of keyboard input to preform an action. On keydown i want to move an object across the window, but stop the object as soon as the key is let up. I have looked in the documentation for AppKit and found the KeyDown function but I cannot seem to figure out how to use it. I want to create a function to call in my game update timer that will preform this. Thanks 
import Cocoa
import Appkit

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

@IBOutlet weak var window: NSWindow!

func applicationDidFinishLaunching(aNotification: NSNotification) {
    // Insert code here to initialize your application

     func keyDown(theEvent: NSEvent) {
        if (theEvent.keyCode == 1){
            println("test")
        }

    }

}

func applicationWillTerminate(aNotification: NSNotification) {
    // Insert code here to tear down your application



}
}
解决方案
Here is some example code:
  override func keyDown(theEvent: NSEvent) {
            if (theEvent.keyCode == 1){
           //do whatever when the s key is pressed
        } 

    }
