CellForRowAtIndexPath is not invoked

I’m writing an app hat has many views and I used sliding views library (ECSlidingViews). The problem is when I fill an array with objects and fill the table with the objects in tableView:cellForRowIndexPath: method, it does present the data in the table, but when I go to other view and come back the data disappears because tableView:cellForRowIndexPath: is not called. Here is the code:

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath   
{   
NSLog(@"begin of cellForRowAtIndexPath");    
SchedualeCell *cell = (SchedualeCell *)[tableView dequeueReusableCellWithIdentifier:@"Cell"];    
Course *temp = [array objectAtIndex:indexPath.row];    
cell.nameLb.text = temp.name;    
cell.hourLb.text = [NSString stringWithFormat:@"%d",temp.hour];    
cell.startTimeLb.text = temp.startTime;    
cell.endTimeLb.text = temp.endTime;    
NSLog(@"End of cellForRowAtIndexPath");    
return cell;    
}

tableView:numberOfRowsInSection: and numberOfSectionsInTableView: is invoked when I come back to the view that has the table view.

  • Remove space between sections in collectionview
  • Xcode “Device Locked” When iPhone is unlocked
  • Xcode stack trace not appearing in console
  • iOS with Parse. PFUser.currentuser() not getting cached. Returns nil after app restart
  • In-app-purchase call function when sucessful
  • xcode duplicate symbols for architecture error after updating cocoa pods
  • P.S.: The view is UIViewController that has table view inside of it, and I searched all StackOverflow before posting my problem.

    EDIT : this is where I set the delegate and datasource

    - (void)viewDidLoad
    {
        [super viewDidLoad];
        NSLog(@"Did Appear");
        // Do any additional setup after loading the view.
        self.view.layer.shadowOpacity = 0.75f;
        self.view.layer.shadowRadius = 10.0f;
        self.view.layer.shadowColor= [UIColor blackColor].CGColor;
    
        if (![self.slidingViewController.underLeftViewController isKindOfClass:[MenuViewController class]])
        {
            self.slidingViewController.underLeftViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"Menu"];
        }
        [self.view addGestureRecognizer:self.slidingViewController.panGesture];
    
        if (array == nil)
        {
            array = [[NSMutableArray alloc]init];
        }
    
        table.delegate = self;
        table.dataSource = self;
        [table reloadData];
    
    }
    

    and I did included The delegate and datasource in the header

    @interface MainViewController : UIViewController<UITableViewDataSource , UITableViewDelegate,addDelegate>
    

    2 Solutions Collect From Internet About “CellForRowAtIndexPath is not invoked”

    First of all , it’s not numberOfRowsAtSection and numberOfTableView. It’s numberOfSectionsInTableView and numberOfRowsInSection.

    Things you can do :

    1) NSLog your numberOfRowsInSection. Note that , If it’s “0” then your cellForRowAtIndexPath is never going to be called.

    2) If you are using your UITableView inside some UIView then you should add :

    [self.view addSubview:table];
    

    3) Don’t Forget to include :

    @interface yourViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
    

    Once check that you reframed the tableview in ViewWillAppear.
    Some times if we set out of frame, CellForRowAtIndexPath will not call.
