How to set content offset and content size in a UIWebView

Question

I have had to change a UIScrollView into a UIWebView due to formatting reasons.

There is a problem though that I need to be able to get the content offset back to 0, 0 (as I am using reusable UIWebViews and changing content) and get the content size so I can place a button at the bottom; but UIWebView does not seem to have this.

Answer 1

Use JavaScript.

I think that the next line should do the magic:

[webView stringByEvaluatingJavaScriptFromString:@"window.scroll(0,0)"];

Answer 2

The best way I found to sort the problem was:

1. Create a UIWebView
2. Put it in a UIScrollView
3. Add the HTML into it using "loadHTMLString"

4. Using the "- (void)webViewDidFinishLoad:(UIWebView *)webView {" delegate method I detect the size of the UIWebView

5. Set the frame of the UIWebView to the content size.

6. Remove interaction from the UIWebView
7. Set the Content size of the UIScrollView to the content size.

Then used the functionality of the UIScrollView instead of the UIWebView.
