Problems with third-party library afnetworking

In the AFSECURITYPOLICY.M class, such three errors are reported

1. Use of undeclared identifier ' Ksecformatunknown '

2. Use of undeclared identifier ' Ksecitempemarmour '

3. Implicit declaration of function ' Secitemexport ' is invalid in C99

After searching online, you will find that you can simply add the following code to the. pch file:

#ifndef Target_os_ios #define Target_os_ios target_os_iphone#endif#ifndef target_os_watch#define Target_os_watch 0 #endif

The current version of Xcode 6 already does not have a. pch file that needs to be created manually, and the specific steps can be found in another article: Why Xcode6 the PCH (precompile Prefix Header) & how to add a PCH file.
