3,881 PointsOr Operators Not Working
Currently working through the Self-Destructing messaging app project and having trouble on the signup page setup portion.
The lesson instructed me to create code to prevent anyone from signing up with a user, pass, and email that has spaces in-between the lettering.
I'm using an if statement to prevent this, but for some reason I'm receiving a "parse issue: expected expression" error when running the code. It states the OR operator is causing this.
Here's my code:
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];
The error points out the failing point at the first ||.
Not sure why this operator isn't working.
If i remove the or operator and just keep the ([username length] == 0), it works just fine.
Appreciate your time,
Ryan

3,881 PointsHey Chris,
Thank you for the response. Unfortunately i made the mistake of accidentally deleting the 0 when I posted this question. I have the 0 listed in my project and it still fails. I've updated the code in the original posting.
Hope we can continue trying to figure this out.

You appear to be missing the operator value for [email length], apart from that your statement should work just fine.

26,676 PointsI just noticed something I didn't the first time around, you have the following
0) || [, the parentheses shouldn't be there.if ([username length] == 0 || [password length] == 0 || [email length] == 0) { /* ... */ }
