    data
    text
    <p>i have an XML file as url where the file contains like this, </p> <pre><code>&lt;Products&gt; &lt;products id="1"&gt; &lt;name&gt;product1&lt;/name&gt; &lt;price&gt;$150&lt;/price&gt; &lt;img&gt;http://www.myimage.com/Main_pic.png&lt;/img&gt; &lt;/products&gt; &lt;/Products&gt; </code></pre> <p>Now using NSXMLParser i can retrieve the data and the image but after i get those data am not understanding how to store in NSMutableArray or NSDictionary. Also i tried to implement lazyloading asynchronous image download from <a href="http://developer.apple.com/library/ios/#samplecode/LazyTableImages/Introduction/Intro.html" rel="nofollow noreferrer">Lazy Loading Table Images Asynchronous Downloading from Apple</a>. But i failed to load the images. Do we have any alternative for aynchronous loading.</p> <p>Kindly describe me in detail about,</p> <ol> <li>how to store a data retieved from url XML file in aysnchronous downloading.</li> <li>how to separate data and image. </li> <li>how to implement those in UIImage and data to view in iPhone. </li> </ol> <p><strong>EDITED</strong></p> <p>for better understanding i need the data and the image like below picture and not in the table view. <img src="https://i.stack.imgur.com/W7DEX.png" alt="Sample Picture"></p> <p><strong>EDITED-2</strong> By using the lazyloading parsing i modified according to my content here the code for your reference,</p> <pre><code>- (void)main{ self.workingArray = [NSMutableArray array]; self.workingPropertyString = [NSMutableString string]; NSXMLParser *parser = [[NSXMLParser alloc] initWithData:dataToParse]; [parser setDelegate:self]; [parser parse]; if (![self isCancelled]){ self.completionHandler(self.workingArray);} self.workingArray = nil; self.workingPropertyString = nil; self.dataToParse = nil;} - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ if ([elementName isEqualToString:@"Products"]){ self.workingEntry = [[egsLists alloc] init];} storingCharacterData = [elementsToParse containsObject:elementName];} - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ if (self.workingEntry){ if (storingCharacterData){ NSString *trimmedString = [workingPropertyString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; [workingPropertyString setString:@""]; if ([elementName isEqualToString:sIDStr]){ self.workingEntry.ProductID = trimmedString;} else if ([elementName isEqualToString:sImageStr]){ self.workingEntry.img = trimmedString;}} else if ([elementName isEqualToString:@"Products"]){ [self.workingArray addObject:self.workingEntry]; self.workingEntry = nil;}}} - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ if (storingCharacterData){ [workingPropertyString appendString:string];}} </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.
