i'm failing to sort the xml data on my tableview. am i suppose to
make a model class for the data and have the table view display/sort
that instead? i'm quite with this one. am i suppose to enter values
in Sort Key and Selector IB fields for each column? doing so returns:
-[NSXMLElement compare:]: unrecognized selector sent to instance
0x162b6430. what am i missing here?
- (IBAction)parseData:(id)sender
{
[progressIndicator setHidden:NO];
[progressIndicator startAnimation:nil];
NSURL *url = [NSURL URLWithString:kXMLWebAddress];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url
cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
timeoutInterval:30]; //cachePolicy: 10.5 or higher
NSData *urlData = [NSURLConnection sendSynchronousRequest:urlRequest
returningResponse:nil error:nil];
NSXMLDocument *doc = [[NSXMLDocument alloc] initWithData:urlData
options:0 error:nil];
[itemNodes release];
itemNodes = [[doc nodesForXPath:@"stations/station" error:nil] retain];
[tableView reloadData];
[progressIndicator setHidden:YES];
[progressIndicator stopAnimation:nil];
}
- (void)dealloc
{
[itemNodes release];
[super dealloc];
}
- (NSString *)stringForPath:(NSString *)xPath ofNode:(NSXMLNode *)node
{
NSError *error;
NSArray *nodes = [node nodesForXPath:xPath error:&error];
if ([nodes count] == 0)
return nil;
else
return [[nodes objectAtIndex:0] stringValue];
}
