Code Challenge: Signing Up New Users Part 2

Hello fellow students and teachers!

I'm having some trouble on the challenge 1 of the Signing Up New Users Part 2.

Here's the question:

In our view controller below we want to sign up new users for our app. In the signup method, start by capturing the username and password from two UITextField properties: 'usernameField' and 'passwordField'. Store the values in the properties 'username' and 'password'.

Here's my answer:

#import "SignupViewController.h"
#import <Parse/Parse.h>

@implementation SignupViewController

@property (strong, nonatomic) IBOutlet UITextField *usernameField;
@property (strong, nonatomic) IBOutlet UITextField *passwordField;

- (IBAction)signup:(id)sender {

    NSString *username = [self.usernameField.text];
    NSString *password = [self.passwordField.text];

}

@end

What am I missing, I really can't pin point the problem, if I know myself it's probably a missing bracket or something :p

Can anyone help me? Thanks ;)

well the code

@property (strong, nonatomic) IBOutlet UITextField *usernameField;
@property (strong, nonatomic) IBOutlet UITextField *passwordField;

does not belong in the .m file, they belong in the .h. I think the question lets you assume they are already defined in the .h

Also, it states you want to store the values of the fields in 2 properties which are already defined. 

NSString *username = [self.usernameField.text];
NSString *password = [self.passwordField.text];

the above code is wrong because you assign the values of the fields to two new objects, not the existing properties.

Try using the self.propertyName style of syntax to assign the field values

There's another syntax error in Rafael's code. Brackets ( [ ] ) in Objective-C are for messages/methods or arrays (if prefixed with the @ character). Hence they should also be removed when accessing the self.usernameField.text and self.passwordField.text properties.

That solved it guys, thanks so much.

I had to assume both the usernameField/passwordField and username/password properties were already defined.

Again, thanks ;)
