Creating a Self destructing message>> Logging In

for some strange reason whenever i try to log in with a user that i just created it always says that i have an invalid username and password. Ive tried deleting users from parse.com and creating new ones, no matter how simple or complex the usernames are the log in credentials don't seem to match for me to login.

Also, i have no errors in my code and it runs just fine.

here's my login view controller.m:

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


if ([username length] == 0 || [password length] == 0)
    {
        UIAlertView *alertView =[[UIAlertView alloc] initWithTitle:@"Oops!"
                                                     message:@"Make sure you enter a username and password!" delegate: nil cancelButtonTitle:@"OK" otherButtonTitles:nil];

    [alertView show];

}
    else {
        [PFUser logInWithUsernameInBackground:username password:password block:^(PFUser *user, NSError *error) {
            if (error) {
            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Please check username and/or password and try again!" message:[error.userInfo objectForKey:@"error"] delegate:nil cancelButtonTitle:@"OK"otherButtonTitles: nil];
            [alertView show];
        }
            else {
                [self.navigationController popToRootViewControllerAnimated:YES];
            }
        }];
    }
}
@end

Verify that your ApplicationId and ClientKey match up if you have multiple applications defined on Parse.

Thanks Amit,

but the applicationId and the ClientKey do match up. I only have one application that is using parse and that's the self destructing message.

The only other suggestion I have would be to add NSLogs to output the contents of username and password. And set breakpoints to step through your code.

I believe all I did was create a new app on parse with another id and etc.. either that or completely started over on the project.
