(NSMenuItem):缺少setter或实例变量 [英] (NSMenuItem): missing setter or instance variable

问题描述

我遇到一个奇怪的错误:

I am encountering a strange error:

2015-04-02 12:20:14.642 test[21167:257788] Failed to connect     
(testApp) outlet from (test.AppDelegate) to (NSMenuItem): missing 
setter or instance variable
inserted id: 122

我在向菜单添加menuItem并将功能连接到菜单时发生.

I occured when a added a menuItem to a menu and connected a function to it.

我不知道问题是什么.该应用程序工作正常，但我认为忽略该错误不是一个聪明的主意. setter或instance变量是什么意思?为什么需要它?

I do not know what the Problem is. The app works fine but i don't think it is a smart idea to ignore the error. What is meant by setter or instance variable? Why is it needed?

更新:这是相关代码:

import Cocoa
import Foundation

@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

@IBOutlet weak var window: NSWindow!
@IBOutlet weak var statusMenu: NSMenu!

let statusItem = NSStatusBar.systemStatusBar().statusItemWithLength(-1)

func applicationDidFinishLaunching(aNotification: NSNotification) {
    let icon = NSImage(named: "statusIcon")

    statusItem.image = icon
    statusItem.menu = statusMenu
    // Time for constant repeat
    NSTimer.scheduledTimerWithTimeInterval(1, target: self, selector: "timerRepeat", userInfo: nil, repeats: true)
}

// Method to call the tracking core
func timerRepeat() {
    //....
}

@IBAction func frontEnd(sender: NSMenuItem) {
    var targetURL : String = NSBundle.mainBundle().resourcePath!
    targetURL = targetURL + "/" + "front.app"
    let workspace = NSWorkspace()
    workspace.launchApplication(targetURL)
}


@IBAction func menuClicked(sender: NSMenuItem) {
    NSApplication.sharedApplication().terminate(self)
}   
}

推荐答案

您的xib文件中的插座已损坏.通常，当您为ivar或属性设置出口，然后不使用Xcode的重命名功能将其删除或重命名时，就会发生这种情况.

You have a broken outlet in your xib file. Usually it happens when you set up an outlet to ivar or property which is later deleted or renamed not using Xcode's rename feature.
