此Html字符串由一个图像标记组成，该标记具有图像的字节数组。我正在尝试加载html字符串，如下所示： -

var nsdata = NSData.FromString(mData);
wvNewsDetail.LoadData(nsdata, "text/html; charset=utf-8", "UTF-8", new NSUrl(""));

但这只是加载实际的Html字符串而不是格式化页面。

如何在WebView中加载此Html字符串？

感谢任何帮助。

Answer 1

text/html; charset=utf-8不是公认的mime类型，请将text/html指定为mime类型。

wvNewsDetail.LoadData(nsdata, "text/html", "UTF-8", new NSUrl(""));
