Ios 如何从UIWebView'；iPhone上的HTML是什么？

我想在我的UIWebView的HTML中使用

temp.jpg
“/>
。

如何引用名为
temp.jpg的本地文件以节省宝贵的加载时间

当然，显而易见的选择是
\temp.jpg
“/>
，但我不知道我的根在哪里

我不知道我的根在哪里

UIWebView
查找与加载的HTML文件相关的文件。因此，它可能是您的应用程序包。
这将创建一个URL对象，其中包含您的文件在磁盘上的位置。然后，您可以使用它输出一个有效的
文件：//
URL字符串，该字符串可在
img
标记中使用

NSURL* fileURL = [[NSBundle mainBundle] URLForResource:@"temp" withExtension:@"jpg"];

NSLog(@"<img src=\"%@\" />", fileURL.absoluteString);

NSURL*fileURL=[[NSBundle mainBundle]URLForResource:@“temp”带扩展名：@“jpg”]；
NSLog（@“”，fileURL.absoluteString）；

让根目录成为应用程序的主捆绑包
 我一直在寻找一个解决方案，发现了以下问题

在我的例子中，工作正常，我有一个本地HTML字符串和一个本地图像
我将图像转换为base 64

您可以使用此网站将图像转换为base64编码


并重写HTML字符串，使base64图像位于图像标记中，如下所示

    <img src="data:image/jpeg;base64,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" alt="Red dot" >



要测试结果，请使用以下联机HTML编辑器


希望它对其他人有帮助，或者可能得到更好的解决方案，祝你好运
它应该是URLForResource:withExtension:而不是pathForResource，那么你就不需要第二行了
