Question

Obviously, I’m new to iOS development, but I could really use somebody’s help. I am building a tab bar application in which I am attempting to load .plists into drill-down table views. The problem is that I can’t seem to get this method right, as I am trying to use the navigation controller for a tab in its ViewController. I’m positive that my error is in the second line.

A37dgAppDelegate *AppDelegate = (A37dgAppDelegate *)[[UIApplication sharedApplication] delegate];
AppDelegate.indNavControl *indNavControl;

Subsequently, I get some errors. Here is the code, and I’ll point out where the errors are:

    if([Children count] == 0) {

    DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];

    [self.indNavControl pushViewController:dvController animated:YES];//Property "indNavControl" not found on object of type "IndustriesViewController"
    [dvController release];
}
else {

    //Prepare to tableview.
    IndustriesViewController *indViewControl = [[IndustriesViewController alloc] initWithNibName:@"IndustryView" bundle:[NSBundle mainBundle]];

    //Increment the Current View
    indViewControl.CurrentLevel += 1;

    //Set the title;
    indViewControl.CurrentTitle = [dictionary objectForKey:@"Title"];

    //Push the new table view on the stack
    [self.indNavControl pushViewController:indViewControl animated:YES]; //Property "indNavControl" not found on object of type "IndustriesViewController"

    indViewControl.tableDataSource = Children;

    [indViewControl release];
}

}

Just to be clear, I have imported the header file of my App Delegate. Any help would be greatly appreciated 🙂

The line AppDelegate.indNavControl *indNavControl; is wrong. I think you don’t need this line at all. And while pushing new view controller you can directly use AppDelegate.indNavControl instead of self.indNavControl,

[AppDelegate.indNavControl pushViewController:...
