ios - Application is going in background -


my application in arc.
in view of application there 1 ground image , on image animations continuously repeating images.

problem : application going in background after time.

i seen , tried lots of thing on stack, google , on apple doc didn't got satisfactory solution.
have 3 question.
(1) how stop ?
(2) there other method release memory manually in arc.
(3) if use [self.view removefromsuperview]; uiview memory didn't released in arc ?

mycode animation is

imageview = [[uiimageview alloc] init]; imageview.image = [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy08" oftype:@"png"]]; [self.view addsubview:imgbubbleanimation];  imageview.animationimages = [nsarray arraywithobjects:                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy01" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy02" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy03" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy04" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy05" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy06" oftype:@"png"]],                                       [uiimage imagewithcontentsoffile:[[nsbundle mainbundle] pathforresource:@"bluecandy07" oftype:@"png"]],                                       nil]; [imageview setanimationrepeatcount:0]; // 0 continuous imageview.animationduration =3.0; [imageview startanimating];

and sound files (played when particular button clicked)

url = [nsurl fileurlwithpath: [[nsbundle mainbundle]                                  pathforresource:@"ect1a" oftype:@"mp3"]]; audiosound = [[avaudioplayer alloc] initwithcontentsofurl:url error:nil]; audiosound.delegate = self; audiosound.volume = 5.0; audiosound.numberofloops = 0; [audiosound play];

i have 15 small sound files 1 view , 15 animations 1 view.
in every particular animation there min 15 images.
help, suggestion, link or tutorial welcome.

do mean background or device go sleep/idle (turns off screen)?

if going idle try

[[uiapplication sharedapplication] setidletimerdisabled:yes];

when animation starts. should set off (no) again, when animation finished.
