真機測試

更換電腦後，真機測試沒法運行怎麼辦？忘記導出P12文件怎麼辦？

   出現下邊錯誤怎麼辦？ 

No valid signing identities (i.e. certificate and private key pair) matching the team ID 「Y4YLL2LL5C」 were found.

Xcode can attempt to fix this issue. This will reset your code signing and provisioning settings to recommended values and resolve issues with signing identities and provisioning profiles.

意思是team id綁定配置文件了。

解決：

     在xcode中右擊target->showInFinder->右擊後點擊顯示包內容->以文本格式打開.pbxproj後綴文件，搜素team，刪除teamId保存下。從新運行便可真機運行
