Question

I use TBXML to download a .xml file from the web. I parse the file correctly and I get all the data I want as I want it.

My problem is that I updated the file on the server, and it did not update in the app. It only updated the file when I deleted and reinstalled the app.

Is there some kind of cache or something ?

This is how I order the fetch :

-(void)getXML {

    NSLog(@"Updating ATC data !");

    // Create a success block to be called when the async request completes
    TBXMLSuccessBlock successBlock = ^(TBXML *tbxmlDocument) {

        // If TBXML found a root node, process element and iterate all children
        if (tbxmlDocument.rootXMLElement)
            [self traverseElement:tbxmlDocument.rootXMLElement];
    };

    // Create a failure block that gets called if something goes wrong
    TBXMLFailureBlock failureBlock = ^(TBXML *tbxmlDocument, NSError * error) {
        NSLog(@"Error! %@ %@", [error localizedDescription], [error userInfo]);
    };

    // Initialize TBXML with the URL of an XML doc. TBXML asynchronously loads and parses the file.
    TBXML *tbxml = [[TBXML alloc] initWithURL: [NSURL URLWithString:@"http://www.mysite.com/myFile.xml"] 
                                      success: successBlock 
                                      failure: failureBlock];

}

And this is how I call it in background:

[self performSelectorInBackground:@selector(getXML) withObject:Nil];

It may be useless to call it in background as TBXML works asynchronously, if someone can confirm that I’ll take it away. Also, I don’t think the code of my traverseElement: method is useful here, because the file is parsed correctly.

Thanks for any help here !

Seems like the problem vanished.. It works fine, but I have no idea why it didn’t work in the first place.
