I wrote this code below to get the length of a textfield and pop up an alert after it, it keeps ask me to declare the length in the #interface, how could I do that?
if ([myTextField length]<=0)
Maybe you should use [myTextField.text length]?
If this wasn't the problem then maybe you could post some codes and the error message to get more clarification ;D
