Touch Move Method issue in cocos2d for iphon4 - objective-c

Question

I am developing one universal puzzle game, in which i have used separate image for iphone4 and for iphone3, iphone4 image is double in size of iphone3 image. My issue is for iphone4, touch area of image for iphone4 image is taking double size, suppose i have an image size for iphone4 is 20*40 and for iphone3 is 10*20, issue is touch area for iphone4 image is 40*80 i don't know how its happening i worked out in my code but i didnt get any solution of this issue, touching is working fine in iphone3, taking with in sprite rectangle.
can you one help me to solve this issue or tell me what i am forgetting to code for iphone4 touching so that its take touch with in sprite (image) rectangle
Thank in advance.
Here is my code:

CCSprite * sp= [CCSprite spriteWithFile:#"1.png"];
sp.position = ccp(touchLocation.x ,touchLocation.y);
// [self addChild:sp z:100];

Answer 1

Do this in your app delegate
[director enableRetinaDisplay:YES];
and make sure your images follows the convention.
e.g. for iPhone3 suppose you have image as image.png then your retina image must be image-hd.png

Answer 2

Well, everything should be in points e.g. i dont think you need the logic around the UIScreen scale property, and your logic for scale=1 should work identically on a retina and non-retina display.
Quick try : change scale > 1.0 to scale > 3.0 (the if should always branch to the else part, which you state 'works' on iPhone 3), just to see if this is correct. If it is, remove the logic around scale altogether and cleanup :) ... In my code, i have not had one legitimate case of figuring out whether the scale is 1.0 or otherwise.
