how to hide empty rows in a UITableView and change the height of the Uitableview based on non-empty rows

Question

I have couple of problems with my UITableView.

1. When I add a UITableview on my page, by default it brings up some fixed number of rows,

Answer 1

I solved the problem by creating a simple UIView as footer view with the same background color as the table background:

(UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section {
    UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 100)] autorelease];
    view.backgroundColor = [UIColor whiteColor];
    return view;
}

Maybe you have to disable scrolling in your table view in addition.

Answer 2

- (void) viewDidLoad
{
  [super viewDidLoad];
  self.tableView.tableFooterView = [[[UIView alloc] init] autorelease];
}

NEW ANSWER

In Swift 2.2, 3.0 and onwards, do the following:

tableView.tableFooterView = UIView()

OLD ANSWER BELOW. KEPT FOR POSTERITY.

If you must use UITableViewStylePlain, and you don't use a footerView for anything else, you can use the following semi-dirty solution if you have ARC enabled.:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *view = [[UIView alloc] init];

    return view;
}

If you have ARC disabled, use the following:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    UIView *view = [[[UIView alloc] init] autorelease];

    return view;
}

This creates an invisible footerView, that appears immediately after the last data-filled cell.

Answer 4

If your tableview has multiple sections, you may try using this:

- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
    if (section == tableView.numberOfSections - 1) {
        return [UIView new];
    }
    return nil;
}

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
    if (section == tableView.numberOfSections - 1) {
        return 1;
    }
    return 0;
}

Answer 5

For Swift:

override func viewWillAppear(animated: Bool) {
    self.tableView.tableFooterView = UIView(frame: CGRect.zeroRect)

// OR 

    self.tableView.tableFooterView = UIView()
}

For C#: (Please don't forget to add using CoreGraphics; )

public override void ViewWillAppear(bool animated)
{
    base.ViewWillAppear(animated);
    this.sampleTableview.TableFooterView = new UIView(frame: CGRect.Empty);
}

Answer 6

- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section 
 { 
     return 0.01f;
 }

and for iOS 7

 self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];
