UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:self.view.bounds];
scrollView.backgroundColor = [UIColor whiteColor];
[self.view addSubView:scrollView];

//Get Image
UIImage *displayImage = [UIImage imageNamed:@""];

//Get Image Size
CGSize imageSize = displayImage.size;

//Add Image View
UIImageView *displayImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, imageSize.width, imageSize.height)];
displayImageView.backgroundColor = [UIColor clearColor];
displayImageView.image = displayImage;
[scrollView addSubView: displayImageView];
[scrollView setContentSize: imageSize];
