How do I create an animated credits page?

Question

I have a UITextView that has a lot of content (e.g. credit view), and I want to create an automatic scrolling view for it (something like the credits page for Firefox) where it automatically scrolls the names

I have tried the following, but it is not smooth, and I also require it to happen automatically when user goes to that view

CGPoint scrollPoint = textView.contentOffset;

scrollPoint.y= scrollPoint.y+10;

[textView setContentOffset:scrollPoint animated:YES];

Any guidance?

Answer 1

Since UITextView is a subclass of UIScrollView, you can use its scrollRectToVisible:animated: method to scroll with animation to any point you wish.

The PageControl sample code demonstrates its use (although it's scrolling horizontally).

CGRect Frame1 = CGRectMake(5.0,5.0, 100.0,400.0);
CGPoint scrollPoint = textView.contentOffset;

scrollPoint.y= scrollPoint.y+100;

[textView setContentOffset:scrollPoint animated:YES];

[textView scrollRectToVisible:Frame1 animated:YES];
NSTimer *time;
