iOS Question

viewForHeaderInSection stopped working in xcode 8

I have a tableView with 2 sections, the sections array is fixed with 2 elements. The headers for the sections showed fine as code shows below in Xcode 7. I just upgraded to Xcode 8, and the section headers don't show anymore, the code below doesn't get called anymore.

Any ideas?

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 18)];
/* Create custom view to display section header... */
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 5, tableView.frame.size.width, 18)];
[label setFont:[UIFont boldSystemFontOfSize:16]];
NSString *date =[sections objectAtIndex:section];
/* Section header is in 0th index... */
[label setText:date];
[view addSubview:label];
[view setBackgroundColor:[DeviceHelper Orange]]; //[UIColor colorWithRed:166/255.0 green:177/255.0 blue:186/255.0 alpha:1.0]]; //your background color...
return view;
}

Answer

Use this method as it is, you will see the header NB : set the delegate and datasource of tableView

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    return 50;
}

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
    return 100;
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 3;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section;
{
    return 5;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath;
{
    static NSString *reuseId = @"reuseid";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseId];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:reuseId];
    }

    cell.textLabel.text = @"Test";

    return cell;
}
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, 18)];
    /* Create custom view to display section header... */
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 5, tableView.frame.size.width, 18)];
    [label setFont:[UIFont boldSystemFontOfSize:16]];
    NSString *date = @"22nd Sept 2016";
    /* Section header is in 0th index... */
    [label setText:date];
    [view addSubview:label];
    [view setBackgroundColor:[UIColor orangeColor]]; //[UIColor colorWithRed:166/255.0 green:177/255.0 blue:186/25

    return view;
}
