因证书问题，Xcode 真机调试时经常遇到的问题

1. This application’s application-identifier entitlement does not match that of the installed application. These values must match for an upgrade to be allowed.

   
   报错截图

报错原因:
虽然开发证书不同，但是手机上已经有一个相同的bundle Identifier的应用。
解决方案:
删除手机上的应用即可！

2. The certificate used to sign "XXX" has either expired or has been revoked. An updated certificate is required to sign and install the application.
   原因:本地没有相关证书.
   解决方案:
   Xcode => Preferences =>Accounts=>Apple IDs列表点击相关用户=>下载证书。

3.The application bundle does not contain a valid identifier.

报错原因: Derived Data导致的问题.
解决方案:
Xcode => Preferences => Locations => 进入 Derived Data => 关闭 Xcode => 删除Derived Data文件夹 => 重启 Xcode => Clean => 重新运行
