重启后iPhone4 SecItemCopyMatching返回-25300 [英] iPhone4 SecItemCopyMatching returns -25300 after reboot

问题描述

我的方法：

+(SecKeyRef)getKeyByTagWithoutAlert:(NSString *)keyTag status:(OSStatus *) status{
    *status = noErr;
    SecKeyRef key = NULL;

    NSMutableDictionary *queryKey = [[NSMutableDictionary alloc] init];

    // Set the key query dictionary.
    [queryKey setObject:(id)kSecClassKey forKey:(id)kSecClass];
    [queryKey setObject:[SecKeyUtility getDataByTag:keyTag] forKey:(id)kSecAttrApplicationTag];
    [queryKey setObject:(id)kSecAttrKeyTypeRSA forKey:(id)kSecAttrKeyType];
    [queryKey setObject:[NSNumber numberWithBool:YES] forKey:(id)kSecReturnRef];

    *status = SecItemCopyMatching((CFDictionaryRef)queryKey, (CFTypeRef *)&key);

    [queryKey release];
    return key;
}

在我重启iPhone4之前它一切正常。在此SecItemCopyMatching返回错误代码为-25300并且我的应用程序停止正常工作。在iPhone3上我没有这个问题，只是工作完美。
你能帮助我吗？

And it works fine until I restart my iPhone4. After this SecItemCopyMatching returns error with code -25300 and my app stoping work properly. On iPhone3 I don't have this problem, just work perfect. Can you help me?

对不起我的英语。

推荐答案

错误 25300 是 errSecItemNotFound ，这意味着没有这样的项目在您的钥匙链中。

Error 25300 is errSecItemNotFound, which means that there is no such item in your key chain.
