Question

I have an error while reading XML files for my iPhone app. I have a new feature on my iPhone app that reads my RSS feed. Everything looks good by but I have this issue:

Error while loading rss. Please check your Internet connection

Here’s my code:

- (BOOL) readRSS {
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
    [[NSURLCache sharedURLCache] setMemoryCapacity:0];
    [[NSURLCache sharedURLCache] setDiskCapacity:0];
    BOOL success = NO;
    NSXMLParser *parser = nil;
    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"http://rss.domain.com/%@.xml", self.currentPage]];
    parser = [[NSXMLParser alloc] initWithContentsOfURL:url];
    [parser setDelegate:self];
    [parser setShouldProcessNamespaces:NO];
    [parser setShouldReportNamespacePrefixes:NO];
    [parser setShouldResolveExternalEntities:NO];
    success = [parser parse];
    [parser release];
    [pool drain];
    return success;
}

Then I have this code:

- (void) cleartbl:(NSInteger)type {
    [[[self rssParser] rssItems] removeAllObjects];
    [_tableView reloadData];
    if(type == 1) {
        UIAlertView *alert = [[UIAlertView alloc] 
                          initWithTitle:@"RSS Feed" 
                          message:@"Error while loading rss. Please check your Internet connection."
                          delegate:nil 
                          cancelButtonTitle:@"OK" 
                          otherButtonTitles: nil];
        [alert show];   
        [alert release];
    }

Then i assign:

if([elementName isEqualToString:@"title"]){
    self.currentItem.title = self.currentItemValue;
}

What is my issue, am I missing something?

The code provided looks good for me, what I would do first is to check if your RSS is valid. I think you have an RSS issue here. You can use the RSS Validation to make sure everything looks good.

I would recommend to sanitize your RSS, keep it very simple, if you only want to display news or articles use letters and numbers in your text and use SEO friendly URLs.

This will simplify the data you are loading from your app and avoid errors like special characters.

Try with a simple RSS with one entry to start and you will see if your code has errors.
