Question

我在注册视图控制器中实现了以下功能（附加到“注册按钮”），如下所示。该函数依赖于Parse，并且通常是无缝的。

但是我目前遇到以下问题：

如果用户错误地插入了无效的电子邮件地址; “else”下列出的错误字符串被激活（这很好），但无论如何都会注册上面输入的用户名和密码。
用户可以将密码字段留空。

任何帮助，尤其是与第1期有关的任何帮助，都会受到极大的赞赏。

registerViewController

// Register user.
- (IBAction)registerUser:(id)sender
{
PFUser *user = [PFUser user];
user.username = self.mobileTextField.text;
user.password = self.passwordTextField.text;
user.email = self.emailTextField.text;

// Show loading HUD.
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_LOW, 0), ^{

[user signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
 {
     if (!error)
     {
         [self performSegueWithIdentifier:@"userRegistered" sender:self];
     }
     else
     {
         NSString *errorString = [[error userInfo] objectForKey:@"error"];
         UIAlertView *errorAlertView = [[UIAlertView alloc] initWithTitle:@"Error"                                                 message:errorString delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
         [errorAlertView show];

         // Dismiss loading HUD.
         dispatch_async(dispatch_get_main_queue(), ^{
             [MBProgressHUD hideHUDForView:self.view animated:YES];
         });
     }
 }];

// End editing.
[self.view endEditing: YES];

});
}

这里有很多问题。

a，你绝对不需要也不应该采取新的主题。 Parse会为你做这件事。你必须改变它。

b，你可能正在寻找解析中的神奇公式“如果（（！成功）||错误）......”

c，在发送电子邮件之前，您应该本地检查该电子邮件是否有效。（即，您不能输入“xyz @ hotmail”或不合理的电子邮件。）

即，您需要编写一个例如“checkThisEmailIsValid”的例程。如果你需要帮助他的大喊大叫。请注意，从概念上讲，这并不容易。您了解解析会尝试验证电子邮件吗？即它会发送其中一封电子邮件“新用户，点击此处验证您的电子邮件！”你对此很熟悉吗？

d，一个很大的秘密是202错误代码

这是来自制作应用程序的一些示例代码，希望它有所帮助！

-(void)_actuallyJoin
   {
   ... do things like check the email is valid

   ... in this app the username is the lowercase email

   PFUser *nuser = [PFUser user];
   nuser.username = [self.email.text lowercaseString];

   ... in this app, the email is the email, password is the password

   nuser.email = self.email.text;
   nuser.password = self.password.text;

   [APP huddie];
   APP.hud.labelText = @"Registering ...";
   APP.hud.detailsLabelText = @"1 of 3 ...";
   ... that is just MBProgressHUD.

   [nuser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
      {
      if ( (!succeeded) || error)
         {
         [APP.hud hide:YES]; .. that's MBProgressHUD

         .. usually, blank the form while app is connecting
         self.email.text = @"";
         self.password.text = @"";
         self.confirmPassword.text = @"";

         if ( error.code == 202 )
            {
            [PFAnalytics trackEvent:@"newAccount"
               dimensions:@{ @"result":@"emailAlreadyUsed" }];

            [self woe:@"That email address is already in use...."];
            [PFUser logOut]; .. don't forget that
            return;
            }

         [PFAnalytics trackEvent:@"newAccount"
            dimensions:@{ @"result":@"connectionWoe" }];
         [self woe:@"Couldn't connect. Please try later"];
         return;
         }

      NSLog(@"step one rego success");
      [self _actuallyJoinStepTwo];
      ... now continue to save other information
      ... for example user's address, age, avatar photo etc.
      }];
   }

在signUpInBackgroundWithBlock函数中包含电子邮件验证
