Ask/Cancel in iOS

[Dan Friedman]

Klaus,

That doesn't tell me if they canceled or entered nothing.  Perhaps they want to set their password to empty?  How do I know if they entered nothing, or they hit "Cancel"?

Seems like as long as the user response is empty, the result is "cancel".  How do you determine a empty response from a request to cancel?
