go to your signup view controller in storyboard, open the connections inspector, find the outlet connection that has a ! next to its name and delete it. you probably changed the name of an outlet in your .h file without removing the old one first.

that worked and fixed 75% of the problem but how do i go about fixing this 2014-02-13 12:49:17.591 Ribbit[22814:70b] -[SignupViewController emailField:]: unrecognized selector sent to instance 0x9a78c10 2014-02-13 12:49:17.596 Ribbit[22814:70b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[SignupViewController emailField:]: unrecognized selector sent to instance 0x9a78c10' *** First throw call stack: thanks so much

alll it says is this 2014-02-13 12:53:36.509 Ribbit[22893:70b] -[SignupViewController passwordField:]: unrecognized selector sent to instance 0x9b72bc0 (lldb)

do you know what to do about this? sorry about this just trying to get the hang of it

when i type in username that works fine. When i type in the password or email field it breaks down

• (IBAction)signup:(id)sender;

thats the line that had the blue arrow "- (IBAction)signup:(id)sender;"

where do i put the breakpoint or is it a general button

this is SignupViewController.m

import "SignupViewController.h"

@interface SignupViewController ()

@end

@implementation SignupViewController

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. }

• (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]; } } @end

i had alot of them so i deleted all of them? where do u want me to place this 1 breakpoint?

i cleared all the breakpoints

when i do debug add exception break point where should i be on the screen

i deleted all the exception break points because i had 4 of them

I did that but how do i find the line. once the app quits i cant seem to fine this blue arrow in the code

it is definitely not doing that because the app doesnt shut down till i start entering in the password or email field then pressing the sign up button

all i get is "2014-02-13 13:06:39.423 Ribbit[23096:70b] -[SignupViewController passwordField:]: unrecognized selector sent to instance 0x9a62390 (lldb) "

basically when i leave a field blank it should bring up a mesasge telling me to add content to the field. the username section works perfectly. Sometimes the password works if i enter that then username. But whenever i touch email and sometimes password the app just quits

nevermind the problem is if i enter anything into 1 field that works even email field but if i switch to entering into another field for instance from username to password or email to password then it quits

i also get this" return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));"

?
