M Markos Well-Known Member Licensed User Longtime User Sep 10, 2016 #1 Hi All The touch event for a panel in iOS behaviour is very different from B4A and unpredictable. I want find out if my assumptions are correct: 1) The Action_Up value is returned when you stop touching the panel 2) The Action_Down value is returned when you start touching the panel and does it repeat until you stop touching 3) The sub syntax is : Sub panel1_Touch(Action As Int, X As Float, Y As Float) As Boolean What I wish to do is to known when the panel is being touched and when it is not and get the coordinates at where it is touched and released/ I am returning true to consume the event but I get weird times the event fires and what action is reported as last experienced. Thanks for any guidance or help in advance as it's driving me crazy

Z Zakerg Member Licensed User Longtime User Sep 12, 2016 #3 I also had some issues with IOS panel touch behavior. My intention was to have the user touch the screen and keep their finger there while a sound effect played and an event triggered. In B4A using the Reflection Library, this works fine. I get the X and Y values one sound and one event is triggered. In B4I if the finger is left in place multiple sound and events can be triggered. I tried a few things to see if I could stop this from happening but nothing seemed to work. In reality I believe users tend to just tap the screen and the touch panel event works good for that. I would probably have had to add a note " For best experience keep finger on screen during sound effect" and that would have been awkward. I am concerned about the results a few user might get with a longer touch. Upvote 0
