iphone - ARC の下の osx で SecItemCopyMatching が依然としてリークする

Question

SecItemCopyMatching でメモリ リークが見つかりました。SFを調査した後、解決策が見つかりました：

__block NSString *certificateName = nil;
SecKeychainRef keychain;
SecKeychainCopyDefault(&keychain);
NSMutableDictionary *attributeQuery = [NSMutableDictionary dictionary];
[attributeQuery setObject: (id) kSecClassIdentity forKey:(__bridge_transfer id) kSecClass];
[attributeQuery setObject: (id) kCFBooleanTrue forKey:(__bridge_transfer id) kSecReturnRef];
[attributeQuery setObject: (id) kSecMatchLimitAll forKey:(__bridge_transfer id) kSecMatchLimit];
CFTypeRef attrResult = NULL;
OSStatus status = SecItemCopyMatching((__bridge CFDictionaryRef) attributeQuery,(CFTypeRef *) &attrResult);<------- here is a leak according Instruments


if (status != errSecItemNotFound) {
    NSArray *attributeResult = (__bridge_transfer NSArray *)attrResult;
    [attributeResult enumerateObjectsUsingBlock:^(id identityFromArray, NSUInteger idx, BOOL *stop) {
        OSStatus status;
        SecCertificateRef cert = NULL;
        status = SecIdentityCopyCertificate((__bridge SecIdentityRef)identityFromArray, &cert);
        if (!status)
        {

または別の解決策：

NSMutableDictionary *attributeQuery = [NSMutableDictionary dictionary];
[attributeQuery setObject: (id) kSecClassIdentity forKey:(__bridge_transfer id) kSecClass];
[attributeQuery setObject: (id) kCFBooleanTrue forKey:(__bridge_transfer id) kSecReturnRef];
[attributeQuery setObject: (id) kSecMatchLimitAll forKey:(__bridge_transfer id) kSecMatchLimit];
CFTypeRef attrResult = NULL;
CFDictionaryRef cfquery = (__bridge_retained CFDictionaryRef)attributeQuery;
OSStatus status = SecItemCopyMatching(cfquery,(CFTypeRef *) &attrResult);<------- here is a leak according Instruments


if (status != errSecItemNotFound) {
    NSArray *attributeResult = (__bridge_transfer NSArray *)attrResult;
    [attributeResult enumerateObjectsUsingBlock:^(id identityFromArray, NSUInteger idx, BOOL *stop) {
        OSStatus status;
        SecCertificateRef cert = NULL;
        status = SecIdentityCopyCertificate((__bridge SecIdentityRef)identityFromArray, &cert);
        if (!status)
        {
            char *nameBuf = NULL;
            CFStringRef nameRef = NULL;
            OSStatus statusNew = SecCertificateInferLabel(cert, &nameRef);
            .....
CFRelease(cfquery)

しかし、どちらもまだ漏れています。
