I need to load an image from a url and set it inside an UIImageView; the problem is that I don\'t know the exact size of the image, then how can I show the image correctly?<

    Just use the size property of UIImage, for example:

    NSURL *url = [NSURL URLWithString:path];
    NSData *data = [NSData dataWithContentsOfURL:url];
    UIImage *img = [[UIImage alloc] initWithData:data];
    CGSize size = img.size;
