Hello,
you give us some informations about "Other important methods of AutoScroller class".
I use so far only this line => [AutoScroller addAutoScrollTo:scrollView];
Pls can you explain and give me some examples how can I write in my code the right lines of the other methods of AutoScroller.
I got errors when I write ... +(AutoScroller*) addAutoScrollTo:(UIScrollView*)scroll:(BOOL)showDoneButtonToolbar:(id<uitextfielddelegate>)textFieldsDelegate;
At which point of my program code I write the other text.


Thnks
