objective-c - 钥匙串请求多个帐户的许可

Question

在我的 MacOS 应用程序中，我存储电子邮件帐户数据，因此 5 个应用程序密码保存在钥匙串中。当应用程序启动时，Keychain 询问 5 次以始终允许... 有没有办法让 Keychain 接受我的应用程序一次？例如，Adium 存储多个帐户数据，并且在其钥匙串中只有一个条目（种类：“Internet 密码”）。

代码签名是避免这种情况的唯一方法吗？

店铺：

+(void)storePasswordKeychainWithPassAndKey:(NSString *)passwordStr:(NSString *)accountNameStr {
const char * accountName = [accountNameStr UTF8String];
const char * password = [passwordStr UTF8String];

OSStatus status;
status = SecKeychainAddGenericPassword(NULL, 
                                      strlen(serviceName), serviceName,
                                      strlen(accountName), accountName,
                                      strlen(password), password, 
                                      NULL);

}

得到

+(NSString *) getPasswordKeychainWithKey: (NSString *)accountNameStr {
    const char * accountName = [accountNameStr UTF8String];
    void *password = nil;
    UInt32 passwordLen = 0;
    SecKeychainItemRef itemRef = nil;

    OSStatus status1;
    status1 = SecKeychainFindGenericPassword(NULL, 
                                             strlen(serviceName), serviceName,
                                             strlen(accountName), accountName,
                                             &passwordLen, &password,
                                             &itemRef);

    if (status1 == noErr) {
        NSData* passwordData = [NSData dataWithBytes:password length:passwordLen];
        SecKeychainItemFreeContent (NULL, password);
        return [NSString stringWithCString:[passwordData bytes] encoding:NSUTF8StringEncoding];
    }

    return nil;
}
