1 +(CCSprite *) convertImageToSprite:(UIImage *) image
2 {
3     CGImageRef cgimage = image.CGImage;
4     CCTexture2D *texture = [[CCTexture2D alloc] initWithCGImage:cgimage resolutionType:kCCResolutioniPhoneRetinaDisplay];
5     CCSprite *sprite = [CCSprite spriteWithTexture:texture];
6     [texture release];
7     return sprite;
