Answer 1

Essayez d'inclure l'en-tête SecCertificatePriv.h ainsi:

#include <Security/SecCertificatePriv.h> 

je vois qu'il comprend la déclaration de la fonction que vous souhaitez utiliser.

... 
/* 
* Private API to infer a display name for a SecCertificateRef which 
* may or may not be in a keychain. 
* This is a candidate for deprecation; use SecItemCopyDisplayNames() instead. 
*/ 
OSStatus SecCertificateInferLabel(SecCertificateRef certificate, CFStringRef *label);
