I'm using a UIWebView for displaying content, in the form of an HTML string – not a website, higher than the screen of the iPhone, without needing to scroll in the webView itself, leaving that to the parent scrollView.

To achieve this, I need a way to get the total document size, including the scrollable area, to set the webView's height. I have tried a number of different Javascript solutions:

(document.height !== undefined) ? document.height : document.body.offsetHeight // Returns height of UIWebView

document.body.offsetHeight // Returns zero

document.body.clientHeight // Returns zero

document.documentElement.clientHeight // Returns height of UIWebView

window.innerHeight // Returns height of UIWebView -2

document.body.scrollHeight // Returns zero

Is there a solution that actually works?

Current (nonworking) code:

[[[self.singlePost.contentText subviews] lastObject] setScrollEnabled:NO];

int content_height = [[self.singlePost.contentText stringByEvaluatingJavaScriptFromString: @document.body.offsetHeight] intValue];

NSLog(@Content_height: %d, content_height);

CGRect rect = self.singlePost.contentText.frame;

rect.size.height = content_height;

self.singlePost.contentText.frame = rect;
