iOS Doubt in parsing rss fields

iphonejudy · Feb 17, 2009

I need to parse rss fields like
<xml>
<item>
<title>title</title>
<description>descriptionsssssssss....</description>
<url>http:/example/example.jpg</url>
</item>
</xml>
I can parse title and description,But the image url is displayed as it is.
How can i parse the image url to display the image?

It sounds like you don't have a parsing question, you have a "how do I load an image from a remote URL?" question.

You should be able to load a UIWebView with the image URL.

You need to understand the difference between parsing and loading URLs. What you want is to load the image from the url you parsed.

UIWebView is waaayy oversized for displaying a single image!! Use UIImageView and load the image yourself. (Don't have the documentation at hand but that is easy).

You mean the component is too heavy-weight? I concur but it's a quick and easy way to do what they want. It won't scale well but perhaps that's not a problem.

To make a UIImage from a URL you want to do something like

Code:

NSString *path = @"http://whateveryoururlis.com/yourimage.jpg";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data cache:NO];

Then put that UIImage in a UIImageView.

I am using the below code to display image from url

NSString *pathimage = vController.currentUrl1;

NSURL *urlImage= [NSURL URLWithString

athimage];

NSData *data = [NSData dataWithContentsOfURL:urlImage];

UIImage *img = [[UIImage alloc] initWithData:data cache:YES];

vController.imageview1.image=img;

But the image is not displayed.Can anyone tell me solution?
