UITabelView reloaded from NSXMLParser (iphone SDK 4.0) - iphone

Question

I am creating application that simply reads data from an XML file and displays it in a table view.
I created a "refresh" button when clicked i want it to redownload the xml file and display it again however it seems to crash my application if there is a XML file already downloaded.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
ipb = [[IPB alloc] init];
sectionTitle=[[NSMutableArray alloc]init];
currentURL=#"http://localhost:8888/xml/Sinnergy.xml";
[self reloadTableView];
[window makeKeyAndVisible];
return YES;
}
-(void)reloadTableView
{
pathURL = [NSURL URLWithString:currentURL];
parser = [[NSXMLParser alloc] initWithContentsOfURL:pathURL];
[parser setDelegate:self];
[parser parse];
[mainTableView reloadData];
}

Answer 1

You are leaking the parser, and if its an instance variable it might cause issues. You should go
NSXMLParser *parser = [[NSXMLParser alloc] initWithContentsOfURL:pathURL];
[parser setDelegate:self];
[parser parse];
[parser release];
Also you are asking the parser to start parsing, but at that point of time you shouldn't be reloading the table, it should be in your
- (void)parserDidEndDocument:(NSXMLParser *)parser
delegate method. Try that and if it still crashes post the crash report
