set username and password challenge

Hey All,

I'm having a bit of trouble with my code challenge. I am supposed to set the 2 properties in the signup method (username and password) to the 2 UITextFields (usernameField and passwordField). With my code below, I get the error: "Make sure you set both the 'username' and 'password' properties!".... Any suggestions? Thanks!

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

@implementation SignupViewController

- (IBAction)signup:(id)sender {
NSString *username = [self.usernameField text];
NSString *password = [self.passwordField text];

}
@end

Because username and password are already properties, you would need to set them using the self. notation 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;
}

@end

That is because we probably already set them up as a NSString in the header file using something like

@property (nonatomic, strong) NSString *username;
@property (nonatomic, strong) NSString *username;

Also, I used self.usernameField.text in my answer, but that is the equivalent of what you put [self.usernameField text]

Both of them work fine once you start using the self. instead of declaring a new NSString.
