Adding the CustomerListController

Goal: Create the customer list view.

1. In the SUP101 Xcode project, select File > New File.
2. In the new File window, select the Cocoa Touch Class group, the UIViewController subclass and the UITableViewController subclass option. Unselect With XIB for user interface, then click Next.
3. In the next window, in File Name, enter CustomerListController.m, ensure that Also create CustomerListController.h is selected, and click Finish.
   The new source files contain stub implementations of various methods.
4. Open the CustomerListController.m file, and add this code:

   #import "CustomerListController.h"
   #import "SUP101AppDelegate.h"
   #import "DetailController.h"
   
   #import "SUP101_Customer.h"
   
   
   @implementation CustomerListController
   @synthesize customerList;
   
   - (id)initWithStyle:(UITableViewStyle)style {
       // Override initWithStyle: if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
       if (self = [super initWithStyle:style]) {
       }
       return self;
   }
   
   
   
   - (void)viewDidLoad {
       // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
       // self.navigationItem.rightBarButtonItem = self.editButtonItem;
       [super viewDidLoad];
   }
   
   - (void)viewWillAppear:(BOOL)animated {
   
       self.title = @"Customers";
       NSMutableArray *array = [[NSMutableArray alloc] init];

       if ([customers length] > 0)
       {
           for (SUP101_Customer * oneRec in customers)
           {
               [array addObject:oneRec];
           }
       }
       self.customerList = array;
       [array release];
       [[self tableView] reloadData];
       [super viewWillAppear:animated];

5. Save the CustomerListController.m file.
6. Open the CustomerListController.h file, and add this code:

   #import <UIKit/UIKit.h>
   #import "DetailController.h"
   
   @interface CustomerListController : UITableViewController
           <UITableViewDelegate, UITableViewDataSource> {
               NSArray *customerList;
               DetailController *childController;
   }
   @property (nonatomic, retain) NSArray *customerList;
   @end
   

7. Save the CustomerListController.h file.
