How do I get the image to display from this?

lukeirvin · October 2011

I am working on feeding in images from an RSS into a UITableView.

Right now I have it set up so that in each cell I can see the URL that points the image which looks like this:

How do I get the image to display in my cell and not this text?

Thanks!

I am parsing the RSS so it is broken down to where I can display only the title, or the date published or the description which holds this img src tag.

Right now I am just using a setText to show the "summary" which is linked to the description in the HTML.

Should I be using NSData to get the data held in the img src tag?

I've looked at a few examples such as LazyTableImages from Apple but this still isn't clicking well with me.

Can someone give me a run through on this please?

Right now my tableview is displaying empty cells.

In the debugger it shows that I am finding each url and placing them in the appropriate cell.

The app is set up right now that when I tap on the cell safari will open to the webpage with the image.

The image is not displaying in the cell though :(

Here's a bit of my code. I'm betting something else should go here but I'm not sure what:


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
	
	static NSString *MyIdentifier = @\"MyIdentifier\";
	
	CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
    
	if (cell == nil) 
       {
        cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
	}
	
	// Set up the cell
	int storyIndex = [indexPath indexAtPosition: [indexPath length] - 1];

       NSDictionary * dictionary = [stories objectAtIndex:storyIndex];
       [cell setLogoImage:[dictionary objectForKey:@\"summary\"]];
     
       return cell;
}

setLogoImage is set in my CustomCell.m file. Here is what I'm doing there:


-(void)setLogoImage:(NSString*)sender
{
	if(sender !=nil)
	{
        NSString*downloadURL = [[NSString alloc] initWithString:sender];
        
        ASIHTTPRequest *request = [[ASIHTTPRequest alloc] initWithURL:[NSURL URLWithString:downloadURL]];
        request.delegate=self;
        [request setDownloadCache:[ASIDownloadCache sharedCache]];
		[request setCachePolicy:ASIOnlyLoadIfNotCachedCachePolicy];
		
        [request startAsynchronous];
	}
}

Howdy, Stranger!
