Xcode / ObjectiveC - Convert UITableViewController into TableView embedded in a UIViewController

I am fairly new to this Native App dev - I have built an app which contains a UITableViewController to display messages - all works fine - but for styling reasons I need to change it from a TableViewController to a tableview embedded within a viewcontroller.

I have made a view controller containing a table view and relevant linked custom cells / fields and altered the associated header file to - 

 @interface NotificationsListTVController : UIViewController

but my table methods no longer fire and I'm not sure how to instantiate them?

(code below) #pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

// Return the number of sections.
return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{

// Return the number of rows in the section.
return self.GPTNotifications.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath     *)indexPath
{

static NSString *CellIdentifier = @"Cell";
static NSString *CellIdentifierRead = @"CellRead";

UITableViewCell *cell;


notifications *n = [self.GPTNotifications objectAtIndex:indexPath.row];



   if (n.read == false) {
    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];



    CustomCellRead *cellReadB = (CustomCellRead *)cell;
    cellReadB.notifTitle.text = n.notifTitleD;
    cellReadB.notifDate.text = n.notifDateD;
    cellReadB.notifMsg.text = n.notifMessage;


 return cellReadB;
}

 else {
    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierRead     forIndexPath:indexPath];



    CustomCell *cellReadB = (CustomCell *)cell;
    cellReadB.notifTitle.text = n.notifTitleD;
    cellReadB.notifDate.text = n.notifDateD;
    cellReadB.notifMsg.text = n.notifMessage;


    return cellReadB;

    }


 }

Make the following changes in NotificationsListTVController.h:

@interface NotificationsListTVController : UIViewController<UITableViewDataSource,UITableViewDelegate>

Also in NotificationsListTVController.m, dont forget to provide these two statements as well.

 tableView.delegate=self ;
 tableView.dataSource=self;

These are required to set the delegate methods.These two statements need to be provided after initializing your tableView. Like for instance :

   tblView = [[UITableView alloc] initWithFrame:CGRectMake(100,200,320,420) style: UITableViewStyleGrouped];


   tblView.delegate = self;
   tblView.dataSource = self;

   [self.view addSubview:tblView];

These methods you are referring to are the delegate methods which cannot be fired directly unlike other ordinary methods.

Hope it Helps!!!

I do it this way in Interface Builder:

  • Make your TableViewController
  • Make your ViewController and add a ContainerView to it
  • Delete the segued embedded ViewController that comes with it
  • Select the ContainerView and draw a connection from viewDidLoad to your TableViewController
  • you'll get only once option: embed

Done. Your TableViewController will now get displayed within your ViewController.

Pass whatever Data you need forward from the ViewController to the TableViewController with the embedded Segue.

Are you setting the delegate and datasource of your tableview to your class?

Something like:

self.myTableView.delegate = self;
self.myTableView.dataSource = self;

When you create a UITableViewController this is done for you, but if you add the table yourself you need to set them.

Also:

@interface NotificationsListTVController : UIViewController <UITableViewDelegate, UITableViewDataSource>
