UITableView delegate and dataSource methods not getting called

Question

I have a UIView which contains a UITableView. The tableview's delegate is set to my UIView, but it never calls the delegate methods:

-(id)init {
    self = [super init];
    if (self) {
        self.tableView = [[UITableView alloc] initWithFrame:self.bounds];
        self.tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth;
        self.tableView.dataSource = self;
        self.tableView.delegate = self;
        self.tableView.scrollEnabled = NO;
        self.tableView.layer.cornerRadius = PanelCornerRadius;
        [self addSubview:self.tableView];
    }
    return self;
}

#pragma mark - UITableViewDelegate methods

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {

    NSLog(@"height for row");
    int height = [self heightForRowAtIndexPath:indexPath];

    return height;
}

#pragma mark - UITableViewDataSource methods

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

    NSLog(@"number of rows");
    if (self.manager.fetchOperation.dataFetchProblem) {
        return 1;
    }

    int numberOfRows = [self.delegate numberOfSectionsInPanel:self];

    return numberOfRows;
}

I've explored every option I can think of, but can't seem to find the root of the problem.

EDIT: Included the numberOfRowsInSection. It could potentially return 0, only it never gets that chance because the "number of rows" NSLog never gets called.

Answer 1

Can you please write the code that you have written on your cellForRowAtIndexPath: method? Because i can't find anything wrong with your code.

Are you calling your UIView from some other ViewController? If yes, how?

I have done something like this once. I declared a method in the UIView like this :

- (void)setUpTableView{
    self.tableview.delegate=self;
    self.tableview.dataSource=self;
}

And then i called the setUpTableView from the view controller i added this view to, like this :

[self.yourView setUpTableView]; 

This might help. Thanks.

Answer 2

I had a similar problem, my solution was because I did not set the number of sections to 1.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}
