Xcode Error: The service is invalid (0XE8000022) 解決方法

Xcode Error: The service is invalid (0XE8000022)

真機調試時趕上以下狀況：

The service is invalid

Please check your setup and try again

(0XE8000022)

這個未越獄設備的解決方法， 很不湊效，未越獄的可能要抹掉數據恢復設置了：

解決辦法：

Xcode and the GDB connection is quite temperamental. The device and your Mac can become unsynchronised with each other. My checklist for this sort of thing:

• Restart Xcode.
• Delete the .app from your iOS device, do a Clean then Rebuild.
• Disconnect, reconnect device.
• Restart iOS device (90% of the time it fixes things)
• If all else fails, restart your Mac (unlikely but it did fix an issue once for me).

可是對於恢復設備這種最有效卻很弱的方法是很坑的，要折騰好久，還要擔憂資料損失

下面介紹個人解決方法，

設備鏈接Mac，Xcode的Organizer中找到設備，

而後在設備的Console裏面就有設備鏈接不上的報錯日誌：

看到這裏就知道緣由了，是鏈接Gdb服務獲取設備號的可執行文件的權限變了，Deamon進程啓動不了， 

個人iPad是越獄的很容易就修復了，無需重啓

在iPad終端（越獄的能夠去Cydia安裝）裏面進入終端輸入命令便可

（無終端的話能夠用ssh鏈接iPhone， 用戶名：root，密碼：alpine）

chmod  a+x  /Developer/Library/Daemons/*

收工能夠繼續連Xcode調試玩了，
