iOS extracting certificate identity: EXC_BAD_ACCESS - ios

Question

I'm developing an iOS application and struggling to extract an identity from a .p12 certificate. I'm still new to objective-c so I'm sure something major is missing. Here's the code:
#implementation P12Extractor
-(SecIdentityRef)getIdentity{
NSString *path = [[NSBundle mainBundle] pathForResource:#"ServerCert" ofType:#"p12"];
NSData *p12data = [NSData dataWithContentsOfFile:path];
CFDataRef inP12Data = (__bridge CFDataRef)p12data;
SecIdentityRef myIdentity;
OSStatus status = extractIdentity(inP12Data, &myIdentity);
if (status != 0) {
NSLog(#"%#",status);
}
return myIdentity;
}
OSStatus extractIdentity(CFDataRef inP12Data, SecIdentityRef *identity){
OSStatus securityError = errSecSuccess;
CFStringRef password = CFSTR("password");
const void *keys[] = { kSecImportExportPassphrase };
const void *values[] = { password };
CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
securityError = SecPKCS12Import(inP12Data, options, &items);
if (securityError == 0) {
CFDictionaryRef ident = CFArrayGetValueAtIndex(items,0); // <<<at this point i get an EXC_BAD_ACCESS(code=2,adress=0x0) error
const void *tempIdentity = NULL;
tempIdentity = CFDictionaryGetValue(ident, kSecImportItemIdentity);
*identity = (SecIdentityRef)tempIdentity;
}
if (options) {
CFRelease(options);
}
return securityError;
}
#end
I've marked the point of error with a comment, I really have no idea why I keep getting this. This code should be the approved solution from Apple dev site.

Your array is still empty when you try to get its first element...
CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
securityError = SecPKCS12Import(inP12Data, options, &items);
if (securityError == 0) {
CFDictionaryRef ident = CFArrayGetValueAtIndex(items,0); // <<<at this point i get an EXC_BAD_ACCESS(code=2,adress=0x0) error
I think the problem could lay with the certificate or with the options you pass in.
