黑线出现在UIWebView的底部。如何清除？ [英] Black line appearing at bottom of UIWebView. How to remove?
问题描述
我在一个嵌入表单元格的webview中渲染一些html。由于某些原因，在webview的底部有一条黑线。我尝试将webview的背景颜色和它的scrollview设置为白色，但这没有改变任何东西。有没有人看过这个？
以下是正在呈现的HTML：
< html>
< head>
< style type =text / css>
a {text-decoration：none; background-color：white;}
< / style>
< title>< / title>
< / head>
< body style =margin：0; padding：0; background-color：white;>
< a href =http：// body /style =
font-family：HelveticaNeue-Light; font-size：20.000000; color：black; -webkit-tap-highlight-color ：rgba（0,0,0,0）;>

这是在iOS7上。
strong> UPDATE：我仍然不确定是什么导致黑线出现，但我设法通过改变我如何设置我的布局约束摆脱它。在我为视图之间的间距设置约束之前，让布局系统确定视图应该是什么大小。我改变它，以便在webview完成加载其内容时显式地设置webview的高度约束。这似乎已经解决了问题，但我还是不明白黑线来自哪里。

- 设置

UIWebView的backgroundcolor到清除code>。

I am rendering some html in a webview that is embedded in a table cell. For some reason there is a black line at the bottom of the webview. I tried setting the background color of the webview and its scrollview to white but this did not change anything. Has anyone seen this before?
Here is the HTML that is being rendered:
<html>
<head>
<style type="text/css">
a {text-decoration:none;background-color:white;}
</style>
<title></title>
</head>
<body style="margin:0;padding:0;background-color:white;">
<a href="http://body/" style=
"font-family:HelveticaNeue-Light;font-size:20.000000;color:black;-webkit-tap-highlight-color:rgba(0,0,0,0);">

</html>
This is on iOS7.
UPDATE: I'm still not sure what is causing the black line to appear but I managed to get rid of it by changing how I setup my layout constraints. Before I was setting constraints for the spacing around the views and letting the layout system figure out the size that the view should be. I changed it to explicitly set a height constraint of the webview when the webview finishes loading its content. This seems to have fixed the issue but I still do not understand where the black line was coming from.
I had same issue and solution is given below :
- Set
UIWebView'sopaquetoNO - Set
UIWebView'sbackgroundcolortoclearcolor.
Note : Both things provided above are necessary.
