UITableView set to static cells. Is it possible to hide some of the cells programmatically?

To hide static cells in UITable:

1. Add this method:

In your UITableView controller delegate class:

Objective-C:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell* cell = [super tableView:tableView cellForRowAtIndexPath:indexPath];

    if(cell == self.cellYouWantToHide)
        return 0; //set the hidden cell's height to 0

    return [super tableView:tableView heightForRowAtIndexPath:indexPath];
}

Swift:

override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    var cell = super.tableView(tableView, cellForRowAtIndexPath: indexPath)

    if cell == self.cellYouWantToHide {
        return 0
    }

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

This method will get called for each cell in the UITable. Once it calls it for the cell you want to hide, we set its height to 0. We identify the target cell by creating an outlet for it:

2. In the designer, create an outlet for the cell(s) you want to hide. The outlet for one such cell is called "cellYouWantToHide" above.
3. Check "Clip Subviews" in the IB for the cells you want to hide. The cells you are hiding need to have ClipToBounds = YES. Otherwise the text will pile up in the UITableView.

You are looking for this solution :

StaticDataTableViewController 2.0

https://github.com/xelvenone/StaticDataTableViewController

which can show/hide/reload any static cell(s) with or without animation!

[self cell:self.outletToMyStaticCell1 setHidden:hide]; 
[self cell:self.outletToMyStaticCell2 setHidden:hide]; 
[self reloadDataAnimated:YES];

Note to always use only (reloadDataAnimated:YES/NO) (dont call [self.tableView reloadData] directly)

This doesn't use the hacky solution with setting height to 0 and allows you to animate the change and hide whole sections

The best way is as described in the following blog http://ali-reynolds.com/2013/06/29/hide-cells-in-static-table-view/

Design your static table view as normal in interface builder – complete with all potentially hidden cells. But there is one thing you must do for every potential cell that you want to hide – check the “Clip subviews” property of the cell, otherwise the content of the cell doesn’t disappear when you try and hide it (by shrinking it’s height – more later).

SO – you have a switch in a cell and the switch is supposed to hide and show some static cells. Hook it up to an IBAction and in there do this:

[self.tableView beginUpdates];
[self.tableView endUpdates];

That gives you nice animations for the cells appearing and disappearing. Now implement the following table view delegate method:

- (float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    if (indexPath.section == 1 && indexPath.row == 1) { // This is the cell to hide - change as you need
    // Show or hide cell
        if (self.mySwitch.on) {
            return 44; // Show the cell - adjust the height as you need
        } else {
            return 0; // Hide the cell
        }
   }
   return 44;
}

And that’s it. Flip the switch and the cell hides and reappears with a nice, smooth animation.
