Question

I user Interface Builder to layout my view and image view. I put a imageView on the view and set it as an outlet. The problem is that no matter what size of image (768*1024、1024*700) I set in my program：

 self.imageView.image = [UIImage imageNamed:self.filename];

The size to be on the screen is always the size of the imageView I set in the Interface Builder. How can I dynamically set the size of the imageView according to the size of the image? Thanks!

Something like:

UIImageView *imageView = [[UIImageView alloc] init];

UIImage *image = [UIImage imageNamed:@"image.png"];
CGSize imageSize = [image size];

imageView.frame = CGRectMake(0, 0, imageSize.width, imageSize.height);
