Hello,
I'm trying to create a custom Facebook friend picker. At the moment almost everything works the way I want it to, except for one thing. I want that when you scroll down and the picker goes from "Angie" to "Bob" that there is a separator with the letter "B". This separator needs to have a different size compared to the other cells in the scrollview. This is working when you scroll down because I check when the first letter changes and at that point I change the cells settings. The problem is when I scroll back up. Because when I scroll back up the change in the first letter is between the "B" and "Angie" and because of that the cell with "Angie" gets changed. I was wondering if there is a way to check if it is scrolling up or down because if I could check that I would be able to change the settings of the "B" instead of "Angie".
Thanks for the help in advance
Kind Regards,
Max Uijlings
