当 Web 视图内容调整大小时确定 UIWebView 高度

Question

我正在使用UIWebView 在我的视图控制器中加载一个小部件我想在小部件内容大小更改时调整框架。

当一个选项被选中两次时，我下面的代码返回原始高度

这是我的代码

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{

    CGRect frame1 = _widget_VW.frame;
    frame1.size.height = 60;
    _widget_VW.frame = frame1;
    [_widget_VW sizeToFit];

    if (navigationType == UIWebViewNavigationTypeLinkClicked) {
        NSLog(@"User tapped a link.");
        [_widget_VW sizeToFit];

        [_widget_VW setSuppressesIncrementalRendering:YES];

        CGRect frame = _widget_VW.frame;
        frame.size.height = 1;
        _widget_VW.frame = frame;
        CGSize fittingSize = [_widget_VW sizeThatFits:CGSizeZero];
        frame.size = fittingSize;
        _widget_VW.frame = frame;

        _VW_activity.hidden = NO;
        [_activityindicator startAnimating];
        [self performSelector:@selector(setup_DATA) withObject:_activityindicator afterDelay:0.01];

        return YES;
    }

    return YES;
}

使用这个。 它对我有用。

#pragma mark - UIWebViewDelegate methods
- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
    CGRect frame = aWebView.frame;
    frame.size.height = 1;
    aWebView.frame = frame;
    CGSize fittingSize = [aWebView sizeThatFits:CGSizeZero];
    frame.size = fittingSize;
    aWebView.frame = frame;
}
