    <p>I am writing an application that parses a HTML string embedded with images and data. I am able to use SDWebImage to cache the images part for later use and it is caching perfectly. However, I need to use the cached image (UIImage) as a replacement for the src in the html string. I think this can be done with some javascript code but I am a total duffer when it comes to javascript and css. Can someone give me some javascript code to change the image src to this UIImage?</p> <p>Code to cache image:</p> <pre><code>-(NSString *)fetchImageUrlFromSummary:(NSString *)summaryData { NSError *error = nil; NSString *urlString = [NSString string]; HTMLParser *parser = [[HTMLParser alloc]initWithString:summaryData error:&amp;error]; if (error) { NSLog(@"%@", error); return nil; } HTMLNode *bodyNode = [parser body]; NSArray *inputNodes = [bodyNode findChildTags:@"img"]; for (HTMLNode *inputNode in inputNodes) { //NSLog(@"%@", [inputNode getAttributeNamed:@"src"]); if ([[inputNode getAttributeNamed:@"src"]hasSuffix:@"png"] || [[inputNode getAttributeNamed:@"src"]hasSuffix:@"jpg"]|| [[inputNode getAttributeNamed:@"src"]hasSuffix:@"jpeg"]) { urlString = [inputNode getAttributeNamed:@"src"]; [SDWebImagePrefetcher.sharedImagePrefetcher prefetchURLs:[NSArray arrayWithObject:urlString]]; } } return urlString; } </code></pre> <p>Code to set the summary string in uiwebview:</p> <pre><code>NSString *summaryString = [[NSString alloc]initWithData:[_htmlData summary] encoding:NSUTF8StringEncoding]; NSString *myDescriptionHTML = [NSString stringWithFormat:@"&lt;html&gt;&lt;head&gt;&lt;style type=\"text/css\"&gt; div{text-align:justify;text-justify:inter-word;margin:auto} img {max-width:100%%;width:auto;height:auto;}body{font-family: Verdana;font-size: 12pt;max-width: 100%%; width:auto; height:auto;} &lt;body bgcolor=\"#F5F5DC\"&gt;&lt;/style&gt;&lt;body&gt;%@&lt;/body&gt;&lt;/html&gt;", summaryString]; [_webView loadHTMLString:myDescriptionHTML baseURL:[NSURL URLWithString:[_htmlData originUrl]]]; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
