for touchdown and touchinside... is it depends on threads on which it runs... because i have faced some problems with this events in my app... and sometimes it happens that they are called randomly...

can anyone explain for touchdown and touchupinside...?????/

Answer 1

TouchDown will fire before TouchUpInside because touch down is the action of your finger touching down on the phone.

TouchUpInside will happen after because it describes the action of your finger lifting up from the down position off of the phone
