iOS Build a Self-Destructing Message iPhone App Using Parse.com as a Backend and Adding Users Signing Up New Users: Part 2 (PFUser)

Challenge task 3 of 4Now let's use the'signUpInBackgroundWithBlock' method to sign up this new user.

Send this message to the newUser variable. For the block parameter, copy and paste the following empty block: ^(BOOL succeeded, NSError *error) {}

the code is as below :

import "SignupViewController.h"

import <Parse/Parse.h>

@implementation SignupViewController

  • (IBAction)signup:(id)sender { self.username = self.usernameField.text; self.password = self.passwordField.text;

    PFUser *newUser = [PFUser user]; newUser.username=self.username; newUser.password=self.password;

    [newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {}] // I add this line ,but cannot work

}

@end

Hi! the only problem I see is the semicolon at the end of the "signUpInBackgroundWithBlock" sentence. Apart from that the code seems to be ok. I've tried it and works for me. Let me know if you continue with the same problem.

Thank you and yes it is only problem miss semicolon.

Francisco Navarro ... I tried using this exact same code, even copied and pasted it but it didn't work, even with the ";" added.

This code did not work for me, can you help by chance? Thanks!

import "SignupViewController.h"

import <Parse/Parse.h>

@implementation SignupViewController

  • (IBAction)signup:(id)sender { self.username = self.usernameField.text; self.password = self.passwordField.text;

    PFUser *newUser = [PFUser user]; newUser.username = self.username; newUser.password = self.password;

[newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {}];

@end
