Answer 2

This may be one example. We basically create a scrollview, set its frame, add content as a preview, and then set the content size. The image (iphone.png) is lower than the iphone screen so we can scroll it.

 UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 20, 320, 460)]; UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"iphone.png"]]; [scrollView addSubview:imageView]; [imageView release]; scrollView.contentSize = CGSizeMake(imageView.image.size.width, imageView.image.size.height); [window addSubview:scrollView]; [scrollView release];

You can use the code below to add a UIScrollView to your view: -

 [self.ScrollView setContentSize:(CGSizeMake(self.view.frame.size.width, self.view.frame.size.height))]; 

Step: 1 Create a UiScrollView,

 @interface ViewController : UIViewController @property (strong, nonatomic) IBOutlet UIScrollView *MyScrollView; @end 

Step 2: In your ViewController.m,

 [self.MyScrollView setContentSize:(CGSizeMake(self.view.frame.size.width, self.view.frame.size.height))];
