In a UITextView i can resize the height of the control to it’s content

  • 0

In a UITextView i can resize the height of the control to it’s content like this:

CGRect frame = textView.frame;
frame.size.height = textView.contentSize.height;
textView.frame = frame;

But i want to use an UIWebView instead in order to show rich text. The UIWebVie’s content is:

NSString *myDescriptionHTML = [NSString stringWithFormat:@"<html> \n"
                                  "<head> \n"
                                  "<style type=\"text/css\"> \n"
                                  "body {font-family: \"%@\"; font-size: %@; }\n"
                                  "</style> \n"
                                  "</head> \n"
                                  "<body>%@</body> \n"
                                  "</html>", @"helvetica",
                                  [NSNumber numberWithInt:12], @"yadayadayada..."];
[webView loadHTMLString:myDescriptionHTML baseURL:nil];

So the UIWebView contains nothing but plain text. How can i achieve result similar to the above UITextView code?

    Although in theory the JavaScript method provided

    - (void)webViewDidFinishLoad:(UIWebView *)webview
    CGRect oldBounds = [[self webview] bounds];
    CGFloat height = [[webview stringByEvaluatingJavaScriptFromString:@"document.height"] floatValue];
    [webview setBounds:CGRectMake(oldBounds.x, oldBounds.y, oldBounds.width, height)];
}

    should work (and seems to work for most people), it just didn’t for me. I tried with a number of variation and it always returned a size that has nothing to do with the true content’s height. A one liner would come up with 260 or 244 height, for instance. Don’t know why (would love to know).

    SO i ended up doing as hinted in this answer:

    - (void)webViewDidFinishLoad:(UIWebView *)aWebView {
    CGRect frame = aWebView.frame;
    frame.size.height = 1;
    aWebView.frame = frame;
    CGSize fittingSize = [aWebView sizeThatFits:CGSizeZero];
    frame.size = fittingSize;
    aWebView.frame = frame;

    NSLog(@"size: %f, %f", fittingSize.width, fittingSize.height);
}

    I think the JS way more elegant but hell, it doesn’t works for me and can’t figure out why, while this method worked out of the box.
