iPhone dev: Increase scroll speed in UIWebView?

Question

I have an app in which I render local HTML files in a UIWebView. The files, however, are sometimes large, and getting to where you want takes a long time with the default scroll

Answer 1

Search for a subview of UIWebView that responds to -setScrollDecelerationFactor: (it's UIScroller - a private class that's the only subview of UIScrollView). You'll find that it takes the same deceleration factors defined for the public UIScrollView class:

- (void)webViewDidFinishLoad:(UIWebView *)aView {
    id decelerator = [aView viewWithSelector:@selector(setScrollDecelerationFactor:)];
    [decelerator setScrollDecelerationFactor:UIScrollViewDecelerationRateNormal];
}

Note that the method I'm using viewWithSelector: is a method I defined in a category of UIView. Presumably, if UIWebView changes in future, my search will return nil and this method will become a no-op.
