Objective c Keychain请求多个帐户的权限

在我的MacOS应用程序中，我存储了电子邮件帐户数据，因此在Keychain中保存了5个应用程序密码。当应用程序启动时，钥匙链要求5次始终允许。。。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，其密钥链中只有一个条目：Internet密码

代码签名是避免这种情况的唯一方法吗

你会发布你用来在Keychain中存储项目的代码吗？

+(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);

    const char * accountName = [accountNameStr UTF8String];
