Question

First i have scaled the layer larger which contains the sprites.
Now I need to sense touch on a sprite.
I have tried as follows, but cant reach to goal-

CGRect tRect= [[aSprite displayedFrame] rect];
    if(CGRectContainsPoint(tRect, touchedPosition))
{
    NSLog(@"touched:>> touch at (%f,%f)",touchedPosition.x,touchedPosition.y);
    // Do something, maybe return kEventHandled;
}
else{
    NSLog(@"NOT touched: touch at (%f,%f)",touchedPosition.x,touchedPosition.y);
}

FYI: I have used cocos2d framework

At last I have found the solution :), here is the code

CGPoint location = [touch locationInView: [touch view]];
CGPoint convertedLocation = [[CCDirector sharedDirector] convertToGL:location];

CGPoint tapPosition = [self convertToNodeSpace:convertedLocation];

where ‘self’ is the sprite holder layer as I have specified before. This layer is listening the touch event.
