ios - Changing the background image using UISwitch -


hi im working on simple app changing background image using uiswitch.

the problem on device pictures in original size. i'm using 960 x 640 png's, should fine on device huge.

thats using. 

- (ibaction)changedstate:(uiswitch*)sender {     uiswitch *switchvalue = (uiswitch*)sender;     [self settorchon:[switchvalue ison]];      if(switchvalue.on)     {        // lights on        self.view.backgroundcolor = [uicolor colorwithpatternimage:[uiimage imagenamed:@"latarka_4_on.png"]];     }     else     {        // lights off        self.view.backgroundcolor = [uicolor colorwithpatternimage:[uiimage imagenamed:@"latarka_4_off.png"]];     } }

make sure have 2 sets of images.-

latarka_4_on.png latarka_4_off.png

for sd resolution (480 x 320). and

latarka_4_on@2x.png latarka_4_off@2x.png

for hd resolution (960 x 640)

chances going wrong if have pngs no suffixes @2x retina resolution.
