empty grid of UItableView using storyboard

I try to display objects of an array in a tableview. This is a single screen app, I'm using storyboard. When running - the tableview appears as an empty grid. the data of the objects is not displayed. what may cause this? Having 2 required methods numberOfRowsInSection and cellForRowAtIndexPath I suspect the last one. The .h file contains this row:

@interface MYViewController : UIViewController  <UITableViewDataSource, UITableViewDelegate>

I set the delegate & datasource via the code as you suggested. still empty grid.

This is my implementation: -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [listRecipes.recipeArray count]; } 

-(UITableViewCell )tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString cellIdentifier = @"ListCellIdentifier"; MYCustomListCell* listCell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; NSString* dataString = listRecipes.recipeArray[indexPath.row]; listCell.listName.text = dataString; listCell.imageView.image = [UIImage imageNamed:dataString]; return listCell; }

I try to display data from an array in MVC . If the array is local - the data is displayed

Can you please advise what to do? Thank you in advanced.

Check if your initialisation of tableview delegate and datasource would be before the recipeArray is initialised. In this case you will have to tableView.reload() after the items are added to recipeArray .

Always remember to hook up your table's delegate and datasources.

Being a UIElement on a UIViewController that conforms to these two protocols is not enough for Xcode to assume that that UIViewController should be the delegate and/or datasource for the table.

Right click on your tableview, drag from delegate & datasource to your UIViewController.

You can also set these programmatically via:

self.table.datasource = self;
self.table.delegate = self;

And if you're still having trouble after this, you'll have to show us how you're implementing the datasource protocol methods.
