iphone - Image on UIbutton visible on simulator but lost on device -

-

i have made application includes movie player in it. video starts playing on touching play button. have set image "play.png" on button , while running on simulator image shows on device image not show up.. checked application on ios 4.3 simulator , installed on device ios 3.2. because of older version ? thanks..

i don't think os version matters. check case of image name , 1 using.

once happened me because of wrong case of image name. image name "portraitbackground.png" , writing "portraitbackground.png". remember simulator running on mac os not ios. anyway, check case , write image name is. think .png , .png treated different haven't experienced it.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
