Easy

NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
    NSURL *bundleBaseURL = [NSURL fileURLWithPath: bundlePath];

    NSLog(@"webview %@", bundlePath);


    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];  
    NSData *htmlData = [NSData dataWithContentsOfFile:filePath];  
    NSString * html =  [NSString stringWithContentsOfFile:filePath encoding:NSStringEncodingConversionAllowLossy error:nil];
    if (htmlData) {  
       [webView loadData:htmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:bundleBaseURL];  
    }

Now in your html you can simply refer to the image as

现在在您的HTML中,您可以简单地将图像称为

Yes. UIWebView has two methods: -loadHtmlString:baseURL: and -loadData:MIMEType:textEncodingName:baseURL:

是。 UIWebView有两个方法:-loadHtmlString:baseURL:和-loadData:MIMEType:textEncodingName:baseURL:

You can get the file data using NSData's -initWithContentsOfFile:, then pass it to the latter of those methods above.

您可以使用NSData的-initWithContentsOfFile:获取文件数据,然后将其传递给上述方法中的后者。

EDIT: Whoops, I didn't notice the img part. But it still should work. Are you trying to load only the image?

编辑:哎呀,我没注意到img部分。但它仍然应该工作。你想加载图像吗?
