通过HTML代码在UIView中使用透明背景颜色 [英] Using transparent background color in UIView by HTML code
问题描述
我试图在UIView中显示广告...我需要将背景颜色设置为透明...我尝试使用，
[viewObject setBackgroundColor：[UIColor clearcolor]];
尽管它使得UIView透明，但它显示的是白色背景......
以下是我试过的HTML代码...
NSString * HTML = [NSString stringWithFormat ：@< html>< head>< meta name = \viewport \content = \width = device-width，user-scalable = no \/>< style> * {margin：0px; padding：0px}< / style>
< / head>< body style = \background-color：transparent \>< div style = \text -align：％@ \>％@< / div>< / body>< / html>，adAlignment，link];
预先感谢...

我不确定if我理解你的问题，但是你的HTML代码应该有一个 UIWebView 。要实现具有透明背景的UIWebView，您只需要做到以下几点：1）将UIWebView的backgroundColor属性设置为[UIColor clearColor]
2）在HTML中使用UIWebView的内容：
$ b
3）UIWebView的opaque属性设置为NO。
以上内容均摘自Apple的 TransWeb 示例代码ReadMe.txt文件。
I'm trying to display an ad in UIView... I need to set the background color to transparent... I tried using,
[viewObject setBackgroundColor:[UIColor clearcolor]];
Eventhough it made the UIView transparent, it is displaying white background...
Below is the HTML code I tried...
NSString *HTML = [NSString stringWithFormat:@"<html><head><meta name=\"viewport\" content=\"width=device-width, user-scalable=no\"/><style>*{margin:0px;padding:0px}</style>
</head><body style=\" background-color:transparent\"><div style=\"text-align: %@\">%@</div></body></html>",adAlignment,link];
Thanks in advance...

I'm not sure if I understood your question, but you should have a UIWebView for your HTML code. To implement a UIWebView with a transparent background all you need to do is
1) set the UIWebView's backgroundColor property to [UIColor clearColor]
2) use the UIWebView's content in the html:
3) the UIWebView's opaque property set to NO.
The above are taken verbatim from Apple's TransWeb sample code ReadMe.txt file.
