Ribbit signUpViewController viewDidLoad method being called twice.

Question

In my Ribbit app I have an NSLog in the viewDidLoad method of my signUpViewController. When I click the "Sign Up" button on my login screen when the app is running the Log in screen pops over, waits a second, then pops over a second time. Additionally, there are two outputs in the console from the NSLog in the viewDidLoad. I can't seem to find a cause for this.

Everything works fine. This is just an annoyance.

Any help is appreciated.

Thanks, Matthew

Here is the code:

LoginViewController.m

@implementation LoginViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.navigationItem.hidesBackButton = YES;

}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


- (IBAction)signUp:(id)sender {

    [self performSegueWithIdentifier:@"showSignUp" sender:self];
}

- (IBAction)login:(id)sender {
    [PFUser logInWithUsernameInBackground:self.usernameField.text password:self.passwordField.text block:^(PFUser *user, NSError *error) {

        if (error) {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops!" message:@"Make sure you have entered a valid username and password." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

            [alertView show];
        }
        else{

            [self.navigationController popToRootViewControllerAnimated:YES];
        }
    }];


}


@end

SignUpViewController.m

@implementation SignupViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"Sing up view loaded.");
}


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

    if (username.length == 0 || password.length == 0 || email.length == 0) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops!" message:@"Make sure you have entered a username, password, and email." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

        [alertView show];
    }

    else{

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

        [newUser signUpInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
            if (error) {

                UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops!" message:@"Make sure you have entered a username, password, and email." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

                [alertView show];
            }

            else{

                [self.navigationController popToRootViewControllerAnimated:YES];

            }
        }];
    }
}
@end
