iphone - 如何以人类可读的形式获取 iOS 根证书列表

Question

我想以人类可读的形式获取 iOS 可信根证书列表。通过编写代码或任何工具。我怎样才能得到它？

我尝试使用来自 here 的一些代码，如下所示，但它返回 null。状态返回 -25300，即未找到项目。

- (void) readCert2 {
    NSMutableDictionary *query = [NSMutableDictionary dictionaryWithObjectsAndKeys:
//                                (__bridge id)kCFBooleanTrue, (__bridge id)kSecReturnAttributes,
                                (__bridge id)kCFBooleanTrue, (__bridge id)kSecReturnRef,
                                  (__bridge id)kSecMatchLimitAll, (__bridge id)kSecMatchLimit,
                                  nil];
    NSArray *secItemClasses = [NSArray arrayWithObjects:
//                             (__bridge id)kSecClassGenericPassword,
//                             (__bridge id)kSecClassInternetPassword,
                               (__bridge id)kSecClassCertificate,
//                             (__bridge id)kSecClassKey,
//                             (__bridge id)kSecClassIdentity,
                               nil];
    for (id secItemClass in secItemClasses) {
        [query setObject:secItemClass forKey:(__bridge id)kSecClass];

        CFTypeRef result = NULL;
        OSStatus status =  SecItemCopyMatching((__bridge CFDictionaryRef)query, &result);
        NSLog(@"%@", (__bridge id)result);
        if (result != NULL) CFRelease(result);
    }
}

答案是，到 iOS 6.1.4 API 为止还不可能。我在苹果论坛上问过，一位苹果开发者这样回答。
