WebView内容无法正确缩放

Question

我正在尝试在UIWebView中加载一些内容，但它没有正确显示。 我在webview周围画了一条红色边缘，并且位置正确。但正如您所看到的，内容上面有一个灰色条。

我在viewDidLoad webview中有以下代码：

productEnergyDetailWebview = [[UIWebView alloc]init];
productEnergyDetailWebview.delegate = self;
productEnergyDetailWebview.scalesPageToFit = YES;
productEnergyDetailWebview.opaque = YES;
[productEnergyDetailWebview setUserInteractionEnabled:true];
productEnergyDetailWebview.autoresizesSubviews = YES;
productEnergyDetailWebview.scrollView.bounces = false;
productEnergyDetailWebview.scrollView.scrollEnabled = false;

更多代码：

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    [topBar removeFromSuperview];
    [self createViews];
    [productEnergyDetailWebview setScalesPageToFit:YES];
    [refreshIndicator stopAnimating];
    [refreshIndicator removeFromSuperview];
    [productEnergyDetailWebview setHidden:false];
}





-(void)createViews{
        productEnergyDetailWebview.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight);
        if(selectedRange != 5 && selectedRange != 4){
            //Add the bar above the detailWebView
            [self createTopBar];
            int xLocation = topBar.frame.size.height + topBar.frame.origin.y;
                [productEnergyDetailWebview setFrame:CGRectMake(self.view.frame.origin.x, xLocation, self.view.frame.size.width, (self.view.frame.size.height - xLocation) - 50)];
                [productEnergyDetailWebview setScalesPageToFit:YES];
                [productEnergyDetailWebview setContentMode:UIViewContentModeScaleAspectFill];
            }

        productEnergyDetailWebview.scrollView.bounces = false;
        productEnergyDetailWebview.scrollView.scrollEnabled = false;
        [productEnergyDetailWebview setUserInteractionEnabled:true];

    }

在这种情况下，谁能告诉我我做错了什么？谢谢

Answer 1

试试这个

self.automaticallyAdjustsScrollViewInsets = NO;

在viewDidLoad

上

编辑：

上面的答案在iOS9上不起作用

此solution from NKorotkov有效：

if (__iOS_9_OR_GREATER__) {

    CGFloat topInset = 20;

    if (self.navigationController) {
        topInset += self.navigationController.navigationBar.bounds.size.height;
    }

    UIEdgeInsets insets = UIEdgeInsetsMake(topInset, 0, 0, 0);

    self.collectionView.contentInset = insets;
    self.collectionView.scrollIndicatorInsets = insets;

}
