iphone - 查看存储在 iPhone 钥匙串中的凭据

Question

我已将登录凭据保存Keychain在我的应用程序中。我需要知道，我是否可以Keychain像在 Mac 中看到或访问凭据存储在 .

我跟着这个教程

    /*write in keychain*/

  KeychainItemWrapper *keychain=[[KeychainItemWrapper alloc]initWithIdentifier:@"Login Credentials" accessGroup:nil];
  [keychain setObject:self.txtusername.text forKey:(__bridge id)kSecAttrAccount];
  [keychain setObject:self.txtpassword.text forKey:(__bridge id)kSecValueData];


  /*read from keychain*/
  NSString *stuname=[keychain objectForKey:(__bridge id)kSecAttrAccount];
  stuname=[stuname stringByAppendingString:@"   "];
  stuname=[stuname stringByAppendingString:[keychain objectForKey:(__bridge id)kSecValueData]];
