无法将值正确存储在钥匙串中 [英] Unable to store values in keychain correctly

问题描述

我正在使用以下内容在钥匙串中存储值:

I am using the following to store values in the keychain:

KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"suggest" accessGroup:nil];       
[keychain setObject:[object valueForKey:@"token"] forKey:(__bridge id)(kSecValueData)];
[keychain setObject:[object valueForKey:@"usr_id"] forKey:(__bridge id)(kSecAttrAccount)];

这是我获取值的代码:

KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"suggest" accessGroup:nil];   
NSLog(@"TOKEN:%@",[keychain objectForKey:(__bridge id)(kSecValueData)]);
NSLog(@"USER NAME:%@",[keychain objectForKey:(__bridge id)(kSecAttrAccount)]);

我还包括了安全框架.

I have also included the security framework.

我已经搜索了stackoverflow和google，但无法在NSLog中获取值.

I have searched stackoverflow and google but am not able to get values in NSLog.

可能是什么原因?

如果有人有，我还可以向我提供其他信息，以便使用钥匙串吗?

One can also Provide me other information if anyone have, in order to work with keychain?

推荐答案

我使用了答案，原因是评论数量有限... 我在一个新项目中尝试了以下代码，下载了KeychainItemWrapper并链接了Security.framework

I use an answer cause comment are limited... I tried the following code out of a new project, downloading KeychainItemWrapper and linking Security.framework

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    {
        KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"suggest" accessGroup:nil];
        [keychain setObject:@"aaaa" forKey:(__bridge id)(kSecValueData)];
        [keychain setObject:@"bbbb" forKey:(__bridge id)(kSecAttrAccount)];
        NSLog(@"TOKEN:%@",[keychain objectForKey:(__bridge id)(kSecValueData)]);
        NSLog(@"USER NAME:%@",[keychain objectForKey:(__bridge id)(kSecAttrAccount)]);
    }

    {
        KeychainItemWrapper *keychain = [[KeychainItemWrapper alloc] initWithIdentifier:@"suggest" accessGroup:nil];
        NSLog(@"TOKEN:%@",[keychain objectForKey:(__bridge id)(kSecValueData)]);
        NSLog(@"USER NAME:%@",[keychain objectForKey:(__bridge id)(kSecAttrAccount)]);
    }

    // Override point for customization after application launch.
    return YES;
}

一切正常.我想您需要提供更多代码才能找到答案.这是我的日志:

Everything works perfectly. I guess you need to provide more of your code in order to find an answer. Here my logs :

2013-11-19 17:11:08.378 test[3430:a0b] TOKEN:aaaa
2013-11-19 17:11:08.379 test[3430:a0b] USER NAME:bbbb
2013-11-19 17:11:08.380 test[3430:a0b] TOKEN:aaaa
2013-11-19 17:11:08.381 test[3430:a0b] USER NAME:bbbb
