Cocoa 函数“SecCertificateInferLabel”的隐式声明在C99中无效

代码OSX山狮：

OSStatus statusNew = SecCertificateInferLabel(cert, &nameRef);

在Subc中生成一条警告，如下所示：

#import <SecurityInterface/SFChooseIdentityPanel.h>
#include <Security/cssmtype.h>
#include <Security/oidsalg.h>
#include <Security/SecCertificate.h>
#include <Security/SecIdentity.h>
#include <Security/SecIdentitySearch.h>
#include <Security/SecPolicySearch.h>
#include <Security/SecTrust.h>
#include <Security/SecIdentitySearch.h>
#include <Security/cssmapi.h>
#include <Security/cssmapple.h>
#include <Security/cssmtype.h>
#include <Security/Security.h>

有什么建议吗？

尝试将标题也包括在内：

#include <Security/SecCertificatePriv.h>

这些头文件是否定义了SecCertificateInferLabel？我试图这么做，但我收到的文件未找到！

...
/*
 * 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);
