Creating a UITableViewController programmatically

Question

This is what I tried. Nothing appears on the screen and none of the UITableView methods that you are supposed to implement are getting called.

-(void)loadVie         


        

Answer 1

The problem is that you're creating a UITableViewController, which is a UIViewController, and will expect to be on the nav stack. What you want to do is create a UITableView, which is a UIView. You are also not setting the table's delegate and data source, which you will need to do to get calbacks.

Your viewDidLoad should look something like this

- (void)viewDidLoad 
{
    [super viewDidLoad];
    UITableView *table = [[[UITableView alloc] initWithStyle:UITableViewStylePlain] autorelease];
    table.dataSource = self;
    table.delegate = self;
    table.frame = CGRectMake(0, 10, 320, 100);
    [self.view addSubview:table];
}

(Note that if you're going to need access to the table outside of the callbacks, you should save it in an ivar rather than declaring it locally, and should retain it. Let me know if you need a few more lines of code to show you what I mean)

Answer 2

iOS7 seems to like this way of init'ing the tableview:

//make tableview
UITableView *table = [[UITableView alloc] initWithFrame:CGRectMake(0, 81, 200, 200) style:UITableViewStylePlain];
table.dataSource = self;
table.delegate = self;
[self.dataView addSubview:table];

try that out. Hope it helps someone.

Answer 3

UIView *newView = [[UIView alloc] initWithFrame:cgRct];
TVC.view = newView;

I'll give you a hint. Here you are setting the view of the UITableViewController to an EMPTY VIEW...

Answer 4

Make sure you set the delegate of TVC, with

TVC.delegate = self;

That's the reason why none of those methods are getting called. Also, make sure your class implements the UITableViewDelegate protocol by changing your interface declaration to

@interface YourViewController : UIViewController <UITableViewDelegate> {
    //declare variables here
}

Also, equally important, don't set TVC.view, as this already happens when you initialize the view controller. You're just setting it to a blank view, which is why you're not seeing anything.
