UIWebView计算高度

第一种：
- (void)webViewDidFinishLoad:(UIWebView *)webView{ float height = [[webView stringByEvaluatingJavaScriptFromString:@”document.body.offsetHeight;”] floatValue]; //document.body.scrollHeight}

第二种：
- (void) webViewDidFinishLoad:(UIWebView *)webView{ CGRect frame = webView.frame; CGSize fittingSize = [webView sizeThatFits:CGSizeZero]; frame.size = fittingSize; webView.frame = frame;}

另外一种
- (void)viewDidLoad { [super viewDidLoad]; webview.delegate = self; [webview loadHTMLString:@”
fdasfda
” baseURL:nil];}- (void)webViewDidFinishLoad:(UIWebView *)webView{NSString *output = [webview stringByEvaluatingJavaScriptFromString:@”document.getElementByIdx_x_x_x(“foo”).offsetHeight;”]; NSLog(@”height: %@”, output);}
