iOS UIWebView with changing content size

Question

I have a UIWebView which i've set the height of the WebView to

[[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight"] floatValue];

This works fine but on my webpage I have a menu which is expandable, so when the webpage is changing it's height the WebView doesn't increase/decrease it's size.

Any tips how I can make my UIWebView change height dynamically when the webpage is changing its size?

I would very much like to keep the UIWebView's size = webpage so I never have to scroll in the WebView.

Answer 1

you can set sizeToFit property and again set Frame of UIWebView in webViewDidFinishLoad

- (void)webViewDidFinishLoad:(UIWebView *)webView{
       [detailsWebView sizeToFit];
       [detailsWebView setFrame:CGRectMake(detailsWebView.frame.origin.x, detailsWebView.frame.origin.y, 300.0, detailsWebView.frame.size.height)];

}

Answer 2

尝试设置其scrollview的contenSize：

detailsWebView.scrollView.contentSize = CGSizeMake(detailsWebView.scrollView.contentSize.width,[[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight"] floatValue]);

Answer 3

使用UIWebView属性scalesPageToFit = YES;
