iphone Programming Glossary: motions

to call touchesMoved on the other scroll views. Unfortunately touchesMoved doesn't get called for scrolling motions as UIScrollView intercepts those motions somehow and uses them to control its scrolling. I started looking around more low.. scroll views.

Getting displacement from accelerometer data with Core Motion

http://stackoverflow.com/questions/4449565/getting-displacement-from-accelerometer-data-with-core-motion

ended up with poor results. I am sure that there won't be an acceptable solution for either larger distances or slow motions lasting for more than 1 or 2 seconds. If you can live with some restrictions like small distances 10 cm and a given minimum.. or 2 seconds. If you can live with some restrictions like small distances 10 cm and a given minimum velocity for your motions then I believe there might be the chance to find a solution no guarantee at all. If so it will take you a pretty hard time..

UIScrollView : paging horizontally, scrolling vertically?

nested UIScrollViews to work. Unfortunately it does not UIScrollView appears to do some additional filtering for fast motions which cannot be disabled so that even if UIScrollView can only be scrolled horizontally it will always eat up and ignore.. so that even if UIScrollView can only be scrolled horizontally it will always eat up and ignore fast enough vertical motions. The effect is so severe that vertical scrolling inside a nested scroll view is unusable. It appears that you have got exactly..
