You can use this method, which is very dynamic and you can specify the starting position of the second image and total size of the image.

-(UIImage *) addImageToImage:(UIImage *)img withImage2:(UIImage *)img2 andRect:(CGRect)cropRect withImageWidth:(int) width     
{

    CGSize size = CGSizeMake(width,40);
    UIGraphicsBeginImageContext(size);

    CGPoint pointImg1 = CGPointMake(0,0);
    [img drawAtPoint:pointImg1];

     CGPoint pointImg2 = cropRect.origin;
     [img2 drawAtPoint: pointImg2];

     UIImage* result = UIGraphicsGetImageFromCurrentImageContext();
     UIGraphicsEndImageContext();
     return result;
}
