How to Detect the Height of a UIWebView

A nifty solution from Stack Overflow.

Here’s my particular implementation, where I simply measure the height of the document.body element:

    NSString *output = [myWebView 
                        stringByEvaluatingJavaScriptFromString:
                        @"document.body.offsetHeight;"];
    NSLog(@"height: %d", [output intValue]);
