In the online document "Managing the Keyboard" under the heading "Moving Content That is Located Under the Keyboard"
There is some nifty code listings
Listing 4-1 Handling the keyboard notifications
Listing 4-2 Additional methods for tracking the active text field.
AND there is some explanation that I mostly follow and have implemented some of the code.
HOWEVER - I get a compile error on "activeField"
The doc says
"The active field is stored in a custom variable (called activeField in this example) that is a member variable of the view controller and set in the textFieldDidBeginEditing: delegate method, which is itself shown in Listing 4-2."
OK OK This is where my knowledge of Objective C breaks down and is lacking.
When I drop in code listing 4-1, I get a precompile error on activeField as "Use of undeclared identifier 'activeField' "
Looking at the 4-2 code I assume that "activeField" is of type (UITextField *)
AND the doc statement that its a custom variable that is a member variable of the view controller
MEANS that I should declare the activeField as a @property in the ViewController interface
@property (UITextField *) activeField;
BUT this yields the following 2 pre-compile errors
1) Unknown property attribute 'UITextField'
2)Type name requires a specifier or qualifier
Clearly I am yet again lost...
Please advise.
Thanks
