开发中真机调试遇到的问题总结

问题1：问题描述：

    Code signing is required for product type 'Application' in SDK 'iOS8.3'

      并且使用真机调试的时候xcode 挂掉了。

 解决方案：

  在工程的code sign 里面修改Provisioning Profile  选择app的描述性文件。然后匹配即可。

1. Search "code sign" in Build settings
2. Change everything in code signing identity to "iOS developer", which are "Don't code sign" originally.
