My ribbit app is not running, i'm getting a error message

You should check if your IBOutlet connection is working correctly. Maybe you renamed your @property? Hover over the outlet @property in your controller to see that it hightlights the correct view in your scene and check the Connections Inspector (the right-most tab in the Utilities panel (which is the right-most panel)) for faulty connections.

Hey, this usually happens when you change the outlet name, but view that was connected to that outlet still holds the reference to the old name. Simple solution: "right click" (or ctrl click) on the item in your storyboard and remove the old outlet in the popup window by simply clicking on the cross.

the error says that you try to add an object to a dictionary with a key that is most likely is nil. Check the part of your code where you write the value from the username field to a NSString.

hmm I can't seem to find an error, I assume this si the code you are talking about

- (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 enter a username, password, and email address!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];

        [alertview show];
    }
}

search your code for this exact string: usernameFeild and replace it with usernameField.

your issue is that you misspelled usernameField :)

What I did? I dont see it lol

Field is written with the i before the e, not after it!

Yeah, thats what I did....where are you seeing the misspelling? Because im having a hard time finding it lol

in your first post. in the error message :)

in xcode you can do shift+cmd+f to find inside a project and search for usernameFeild

Im getting "NO Results for usernameFeild" Thats weird, because I see that in the error message, but every time i spelled usernameField, I spelled it correctly. I did however spelled it wrong when setting up my storyboard properties, but i corrected it. Maybe thats is why idk

thats weird, got any possibility to zip and upload your project. I'll have a look at it.

Im not sure 100% how to do that lol

thats a possibility, but I never liked this solution. Doesn't really help with understanding what issue is and that is actually valuable information.

Ok yeah that worked, it must of saved the misspelled version, even though i changed it.
