Question

我有一个很大的困境。我的应用程序正在运行解析sdk 1.1.12这是最新的。它会定期告诉新的注册用户名是在没有的情况下获取的。我的注册被分成三个独立的控制器，每个屏幕都有一个控制器，我将之前的注册信息传递给发生signUpInBackgroundWithBlock的最后一个控制器。

我的猜测是我在注册前以某种方式操纵用户名？我把它转换为小写。注册确实在大部分时间都有效，这是我无法弄清楚的优势。它会抛出error.code 202，这是用户名，但我保证在发生错误时不会使用它。

它仍然会注册用户并将其成功存储在数据库中。当用户在警报上点击时，我会显示它或者将它们带入应用程序，或者他们终止应用程序并重新打开它。当他们重新打开应用程序时，它会将它们带入主屏幕。

这是我的代码：

 func parseSignUpUser() {
 // creating the new user
 self.showHudWithTitle("Signing Up...")

 user.username = self.email!.lowercaseString
 user.password = self.password
 user.email = self.email!
 user["fullName"] = self.firstName!+" " + self.lastName!
 user["University"] = self.universityName
 user["Sex"] = self.gender
 user["Age"] = NSNumber.init(long: ageNow!)

 // If user seleceted a profile image save it
 if (self.profileImageVw.image != nil) {
  let profileData = UIImageJPEGRepresentation(self.profileImageVw.image!, 0.5)
  let profileFile = PFFile(name: "profilePicture.png", data: profileData!)
  let thumbnailData = self.profileImageVw.image ? .resizeImage()
  let thumbnailFile = PFFile(name: "thumbnailPicture.png", data: thumbnailData!)
  user["profilePicture"] = profileFile
  user["thumbnailImage"] = thumbnailFile

  let myImageName = "profile.png"
  let imagePath = DBAccessManager.sharedInstance.fileInDocumentsDirectory(myImageName)
  self.saveImage(UIImage(data: thumbnailData!) !, path: imagePath)

 }
 user.signUpInBackgroundWithBlock {
   (succeeded: Bool, signUpError: NSError ? ) -> Void in

    if signUpError == nil {
      //successfully sign up the user 
   } else {
     //If email has been used for another account kPFErrorUserEmailTaken
    if (signUpError!.code == 202) {
     appDelegate.log.info("Error Code 202: Email Taken")

     let alertController = UIAlertController(title: "Sign Up Failed", message: "Sorry! Email has been taken! ", preferredStyle: .Alert)
     appDelegate.log.error("Error on 202")

     let OKAction = UIAlertAction(title: "OK", style: .Default) {
      (action) in
      // ...
     }
     alertController.addAction(OKAction)

     MBProgressHUD.hideAllHUDsForView(self.view, animated: true)

     self.presentViewController(alertController, animated: true) {
      // ...
     }
    }    
    else if (signUpError!.code == 203) {
     //If email has been used for another account kPFErrorUserEmailTaken                       ...
    } else if (self.profileImageVw.image == nil) {
     // If the user does not have an image show alert 
     ...
    } else {
     // all other cases show alert 
     ...
    } 
   }
  } // end of parseSignUpUser()
}
