Add toolbar to UITableViewController

Question

What is the simplest way to add UIToolBar to UITableViewController? I\'m depending on edit functionality, so I can\'t change UITableViewController to UIViewController easily.

Answer 1

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    //Initialize the toolbar
    toolbar = [[UIToolbar alloc] init];
    toolbar.barStyle = UIBarStyleDefault;

    //Set the toolbar to fit the width of the app.
    [toolbar sizeToFit];

    //Caclulate the height of the toolbar
    CGFloat toolbarHeight = [toolbar frame].size.height;

    //Get the bounds of the parent view
    CGRect rootViewBounds = self.parentViewController.view.bounds;

    //Get the height of the parent view.
    CGFloat rootViewHeight = CGRectGetHeight(rootViewBounds);

    //Get the width of the parent view,
    CGFloat rootViewWidth = CGRectGetWidth(rootViewBounds);

    //Create a rectangle for the toolbar
    CGRect rectArea = CGRectMake(0, rootViewHeight - toolbarHeight, rootViewWidth, toolbarHeight);

    //Reposition and resize the receiver
    [toolbar setFrame:rectArea];

    //Create a button
    UIBarButtonItem *infoButton = [[UIBarButtonItem alloc]
                                   initWithTitle:@"back" style:UIBarButtonItemStyleBordered target:self action:@selector(info_clicked:)];

    [toolbar setItems:[NSArray arrayWithObjects:infoButton,nil]];

    //Add the toolbar as a subview to the navigation controller.
    [self.navigationController.view addSubview:toolbar];



[[self tableView] reloadData];

}

- (void) info_clicked:(id)sender {


 [self.navigationController popViewControllerAnimated:YES];
    [toolbar removeFromSuperview];

    }

And in Swift 3:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    //Initialize the toolbar
    let toolbar = UIToolbar()
    toolbar.barStyle = UIBarStyle.default

    //Set the toolbar to fit the width of the app.
    toolbar.sizeToFit()

    //Caclulate the height of the toolbar
    let toolbarHeight = toolbar.frame.size.height

    //Get the bounds of the parent view
    let rootViewBounds = self.parent?.view.bounds

    //Get the height of the parent view.
    let rootViewHeight = rootViewBounds?.height

    //Get the width of the parent view,
    let rootViewWidth = rootViewBounds?.width

    //Create a rectangle for the toolbar
    let rectArea = CGRect(x: 0, y: rootViewHeight! - toolbarHeight, width: rootViewWidth!, height: toolbarHeight)

    //Reposition and resize the receiver
    toolbar.frame = rectArea

    //Create a button
    let infoButton = UIBarButtonItem(title: "Back", style: UIBarButtonItemStyle.plain, target: self, action: #selector(infoClicked))

    toolbar.items = [infoButton]

    //Add the toolbar as a subview to the navigation controller.
    self.navigationController?.view.addSubview(toolbar)
}

func infoClicked() {
    //Handle Click Here
}
