empty grid of UItableView using storyboard

Question

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.

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.
