CHAPTER 9: Navigation Controllers and Table Views

Adding a Rows Control Controller Instance

Now, all we need to do is add this controller to the array in BIDFirstLevelController. Single-click BIDFirstLevelController.m, and import the header file for the BIDRowControlsController class by adding the following line of code just before the

@implementation line:

#import "BIDRowControlsController.h"

Then move on and add the following code to viewDidLoad:

- (void)viewDidLoad { [super viewDidLoad];

self.title = @"Root Level";

NSMutableArray *array = [[NSMutableArray alloc] init];

// Disclosure Button

BIDDisclosureButtonController *BIDDisclosureButtonController = [[BIDDisclosureButtonController alloc]

initWithStyle:UITableViewStylePlain]; BIDDisclosureButtonController.title = @"Disclosure Buttons"; BIDDisclosureButtonController.rowImage = [UIImage

imageNamed:@"BIDDisclosureButtonControllerIcon.png"]; [array addObject:BIDDisclosureButtonController]; [BIDDisclosureButtonController release];

// Checklist

BIDCheckListController *checkListController = [[BIDCheckListController alloc] initWithStyle:UITableViewStylePlain];

checkListController.title = @"Check One"; checkListController.rowImage = [UIImage

imageNamed:@"checkmarkControllerIcon.png"]; [array addObject:checkListController]; [checkListController release];

// Table Row Controls

BIDRowControlsController *rowControlsController = [[BIDRowControlsController alloc] initWithStyle:UITableViewStylePlain];

rowControlsController.title = @"Row Controls"; rowControlsController.rowImage = [UIImage imageNamed:

@"rowControlsIcon.png"];

[array addObject:rowControlsController];

self.controllers = array;

}

Save everything, and compile it. This time, you should see yet another row when your application launches (see Figure 9–16).

Figure 9–16. The Row Controls controller added to the root level controller

If you tap this new row, it will take you down to a new list where every row has a button control on the right side of the row. Tapping either the button or the row will show an alert telling you which one you tapped (see Figure 9–17).
