應用程序不啓動在系統重新啓動

Question

我創建了運行的應用程序

sudo launchctl load /Library/LaunchDaemons/com.testapp.plist 

這裏是我的com.testapp.plist一個LaunchDaemon服務：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> 
<plist version="1.0"> 
<dict> 
    <key>Label</key> 
    <string>com.testapp</string> 
    <key>OnDemand</key> 
    <false/> 
    <key>UserName</key> 
    <string>root</string> 
    <key>GroupName</key> 
    <string>wheel</string> 
    <key>KeepAlive</key> 
    <true/> 
    <key>StandardErrorPath</key> 
    <string>/var/log/OutputLog1.log</string> 
    <key>StandardOutPath</key> 
    <string>/var/log/OutputLog2.log</string> 
    <key>ProgramArguments</key> 
    <array> 
     <string>/usr/local/TestApplication/Test.app/Contents/MacOS/Test</string> 
    </array> 
</dict> 
</plist> 

這是工作的罰款。但是當我重啓我的系統時，launchdaemon啓動我的應用程序，但它殺死了應用程序。

登錄我在控制檯得到的是，

我還檢查應用程序從活動監控運行狀態，這表明應用程序正在運行。

通過

sudo launchctl list | grep testapp 

這也表明守護進程還運行還檢查守護進程狀態。

此外，以下是守護進程的plist我的標準輸出日誌（它記錄了我在我的應用程序做了日誌）：

我不能夠得到這個問題的主要原因。

請幫忙。

在此先感謝。

由於this answer顯示，錯誤消息：

不受信任的應用程序是不允許登錄之前連接到窗口服務器。

是誤導的，因爲它表明這個問題是信任一個，當現實中的問題是，你正在試圖GUI操作從錯誤的上下文。

啓動守護進程獨立於系統上下文運行，並且可能在任何用戶登錄之前運行，並且無法訪問Window Server - 它們無法呈現UI。

總之：如果您的應用程序提供了一個用戶界面，它不能運行爲守護程序。

相比之下，發射劑（從/Library/LaunchAgents和~/Library/LaunchAgents加載）能夠呈現的GUI，Apple recommends against it的。

也許你需要的僅僅是創建一個登錄項，儘管你必須在每個用戶的基礎上創建它。
