ios - iPhone中的UiWebview根据内容大小调整大小

Question

我遇到了一个问题，比如我在 Iphone 中使用 UIWebView，数据以 HTML 形式存储，将 html 数据存储为字符串并传递给 UIWebView，但 我想根据内容大小更改 UIWebView 大小

    - (void)viewDidLoad {
        web.delegate = self; 
        NSString * str = [dict objectForKey:@"terms"];
        [web loadHTMLString:str baseURL:nil];
    }
- (void)webViewDidStartLoad:(UIWebView *)webView
{
        CGRect frame = web.frame;
        frame.size.height = 1;

        CGSize fittingSize = [web sizeThatFits:CGSizeZero];
        frame.size = fittingSize;
        web.frame = frame;

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

     web.frame = CGRectMake(10, 100, web.scrollView.contentSize.width, web.scrollView.contentSize.height);

}

Answer 1

设置您的web view delegate和 frame .

 yourwebview.frame=[[UIScreen mainScreen] bounds]; 
 yourwebview.delegate = self;

end 然后使用这个委托(delegate)方法来设置高度。

- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
        CGSize contentSize = aWebView.scrollView.contentSize;
        NSLog(@"webView contentSize: %@", NSStringFromCGSize(contentSize));
        yourwebview.contentsize = contentSize;
    }
