Dear All
Being a newbie, I divided my application into small separate application and they all worked fine. now when I am trying to integrate, problem arises.
I am trying to post some part of the project's code where I am facing the real problem. May be my fundamentals are wrong. But plz help, I am ready to work on it.
SimpleTableViewAppDelegate.h
@class RootViewController;

UISplitViewController *splitViewController;
RootViewController *rootViewController;
DetailViewController *detailViewController;

splitViewController.viewControllers=[NSArray arrayWithObjects:rootNav,detailViewController,nil];
splitViewController.delegate=detailViewController;
[window addSubview:splitViewController.view];
XML_Parser *xmlp =[[XML_Parser alloc] init];
[xmlp xmlparse];
[window makeKeyAndVisible];
}
RootViewCOntroller.m
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

}
// Set up the cell.

cell.textLabel.text = timeZoneName;

Queries:
1. In split view, navigation controller is not visible. Only root view and detail view are visible (and so even after pushing object of SubTable class, its not visible.).
2. I am trying to call 'xmlparse' method (which again invokes 2 nested methods) defined in XML_Parse class but Its not getting accessed from inside SimpleTableViewAppDelegate.m
(Getting warning as:"warning: 'XML_Parse' may not respond to '-xmlparse' ")
XMLparsing code is correct as it is working good when tested separately.
