objective c - Bizarre unwanted animation occurring in iPhone app -


i hate post seeing unwanted animation in iphone app working on. have never seen before in apps or other apps.

this app ios 4.2 , iphones only. weirdness happening on iphone4.

examples:

  • when application in question launches uialertview, "flies in top or top left."

  • when uitableview scrolls, new (standard) cell data "expands in left of cell" when first coming view , populated.

  • when uitextfield has text entered it, typing slow , can see cursor slide right on new letter. if there "clear" button in uitextfield, slides left side uitextfield first entered into.

  • when uipickerview scrolling, scrolling newly displayed row "flying" new row data in top left.

the overall behavior old old old apple ii+ basic set "speed=20" , "slow" computer down.

what know: happening on multiple phones (4 , 3gs). not happen in other apps. not happen in other apps in general. seems consistent across entire app. not small project not when started, did not begin behavior. there no animation associated mentioned items. problem seems affecting in application.

there example of free standing code base app, when integrated prpoblem app, displays same problems.

has seen such behavior before? not sole developer there possible setting else set causes this?

it sounds you're leaving uiview animations un-finished. if begin animation never finish it, uiview manipulations after point animated, describe. odd part thought uikit terminate them (and log message) if control passed runloop open animation block. either no longer happens, or you're starting new animation blocks.

you should on code instances of +[uiview beginanimations:context:] , ensure they're balanced corresponding +[uiview commitanimations].
