@implementation SignupViewController

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


I have also tried the stringWithTrimmingCharactersInSet similar to the previous video and that one doesn't work either. Is it not working because I am trying to store the values as strings?

can you try this:

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

Yes, I did try this as well since this is the way it was done in the previous video but I get the feed back Bummer! Make sure you set both the 'username' and 'password' properties!

Are the textFields on the viewController in the storyboard connected to the properties on the .h file? This link https://developer.apple.com/library/ios/documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/ManageTextFieldTextViews/ManageTextFieldTextViews.html could be of some for you in how to use textFields.

I figured out the answer I just had one question regarding this. In the video Ben assigned the username and password to a string. If I use the following code what is it being stored as? Does the .text make it a string? self.username = self.userNameField.text;
