Objective C version of this solution with top image re-centered logic :

-(UIImage *)getImageInclosedWithinAnotherImage
{
    float innerImageSize = 20;
    UIImage *finalImage;

    UIImage *outerImage = [UIImage imageNamed:@"OuterImage.png"];
    UIImage *innerImage = [UIImage imageNamed:@"InnerImage.png"];

    CGSize outerImageSize = CGSizeMake(40, 40); // Provide custom size or size of your actual image
    UIGraphicsBeginImageContext(outerImageSize);

    //calculate areaSize for re-centered inner image
    CGRect areSize = CGRectMake(((outerImageSize.width/2) - (innerImageSize/2)), ((outerImageSize.width/2) - (innerImageSize/2)), innerImageSize, innerImageSize);
    [outerImage drawInRect:CGRectMake(0, 0, outerImageSize.width, outerImageSize.height)];
    [innerImage drawInRect:areSize blendMode:kCGBlendModeNormal alpha:1.0];

    finalImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return finalImage;
}
