Xcode Error: The service is invalid (0XE8000022) 解决方法

Xcode Error: The service is invalid (0XE8000022)

真机调试时赶上以下状况：

The service is invalid

Please check your setup and try again

(0XE8000022)

这个未越狱设备的解决方法， 很不凑效，未越狱的可能要抹掉数据恢复设置了：

解决办法：

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).

可是对于恢复设备这种最有效却很弱的方法是很坑的，要折腾好久，还要担忧资料损失

下面介绍个人解决方法，

设备链接Mac，Xcode的Organizer中找到设备，

而后在设备的Console里面就有设备链接不上的报错日志：

看到这里就知道缘由了，是链接Gdb服务获取设备号的可执行文件的权限变了，Deamon进程启动不了， 

个人iPad是越狱的很容易就修复了，无需重启

在iPad终端（越狱的能够去Cydia安装）里面进入终端输入命令便可

（无终端的话能够用ssh链接iPhone， 用户名：root，密码：alpine）

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

收工能够继续连Xcode调试玩了，
