How to remove cell from static UITableView created in Storyboard

Question

This should be easy, but I\'m having trouble.

I have a static UITableView with a cell that I would like to remove programmatically if it\'s not needed.

I have a

Answer 1

Use index path to identify the cell in tableview height delegate and return 0

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

        if someCondition {

            if indexPath.row == 1 || indexPath.row == 2 || indexPath.row == 3 {
                return 0 
            }

        }else{

            if indexPath.row == 4 {
                return 0 
            }

        }


    return super.tableView(tableView, heightForRowAt: indexPath)
}

Answer 2

You can't really deal with this in the datasource since with static tables you don't even implement the datasource methods. The height is the way to go.

Try this:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (cell == cell15 && cell15ShouldBeHidden) //BOOL saying cell should be hidden
        return 0.0;
    else
        return [super tableView:tableView heightForRowAtIndexPath:indexPath]; 
} 

Update

It appears that, under autolayout, this may not be the best solution. There is an alternative answer here which may help.

Set the cell you want to hide to hidden somewhere in your code. Add this code: (If your cell has different row height, then you need to override more functions)

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    int rowCount=0;
    for ( int row=0; row<[super tableView:tableView numberOfRowsInSection:section]; ++row){
        NSIndexPath* path=[NSIndexPath indexPathForRow:row inSection:section];
        UITableViewCell* cell=[super tableView:tableView cellForRowAtIndexPath:path];
        if (!cell.hidden){
            ++rowCount;
        }
    }
    return rowCount;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    int realRow=-1;
    for ( int row=0; row<[super tableView:tableView numberOfRowsInSection:indexPath.section]; ++row){
        NSIndexPath* path=[NSIndexPath indexPathForRow:row inSection:indexPath.section];
        UITableViewCell* cell=[super tableView:tableView cellForRowAtIndexPath:path];
        if (!cell.hidden){
            ++realRow;
        }
        if (realRow==indexPath.row)
            return cell;
    }
    return nil;
}

Answer 4

It for only constant cell

-(void)tableViewSearchPeopleCellHide:(BOOL)hide{

    searchCellShouldBeHidden=hide;
    UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0]];
    [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0] atScrollPosition:UITableViewScrollPositionTop animated:YES];
    cell.hidden=hide;
    self.searchPeople.hidden=hide;//UILabel
    [self.tableView reloadData];
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
   // UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (searchCellShouldBeHidden) //BOOL saying cell should be hidden
        return 0.0;
    else
        return [super tableView:tableView heightForRowAtIndexPath:indexPath];
}

Depending on how your table is supposed to work, in your data source you can implement tableView:numberOfRowsInSection: to return 0 rows for the section based on your necessary logic.

Updated for your comment:

The section parameter will be populated by iOS when your implementation is called so all you need is a switch to handle the section that has the row you ant removed/hidden. Example below:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    switch(section) {
        case 0:  // first section of your table, change for your situation
             return 0;
        default:
             return 0;
    }
}

Answer 6

The first thing you can do is tag the cell from storyboard which you want to hide. Put some standard number which you can identify.

Add this code.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];
    if (cell.tag==10) { //I have put 10 for some static cell.       
                cell.hidden=YES;
                return 0;         

    }
     cell.hidden = NO;
    return [super tableView:tableView heightForRowAtIndexPath:indexPath];
}
