Ribbit - Setting Up Parse and Checking UN, PW, Em for blank characters.

This happens when you add a connection, then rename it in your property declaration later on

go to your storyboard and open the connections editor (its near the attributes, size inspector etc) you will see a connection to your password text field (possibly more than one). remove it by clicking the x. then delete your code in your .h that declares the password text field as a property. then click and drag from your text field in storyboard to your .h to reconnect the property. make sure you give it the same name as you used to reference in your code. That should fix it.

Hi Dan go into your stack trace when the app crashes this will tell you when the error is coming up and pop on your break points to see which line is throwing out the error.

From this error

2014-05-10 07:48:47.045 Ribbit[537:60b] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key passwordField.'

From your code it will be one of these things

1. You have a property which is not referenced properly, you may have changed its name or deleted it in that view controller. You will see what I mean when you fire it up in Xcode that there is broken link.

2. Or you have an Object within your view controller class which you have defined a property type for an object which it can't accessed. When it says

'key value coding-compliant for the key passwordField.'

Your object which you have defined is unable to access a value defined simply because it was maybe the wrong type. Remember with objects it key-value pairing and using the key to get the value. So I think in this case you have a key passwordField which can't seem to access it's property ( that is the user password) likely hood there should be a NSString for it to access when it runs this method that you may have not defined as a parameter of the object.

It could be that you typed a @"PasswordField" instead of passwordField and its throwing a error.

Without your code I can't go into it much more detail but just from your console output thats what I would make a educated guess at.

Hope this helps!!
