    没问题, UITableViewController UIViewController . 在iPhone OS 3.0中,任何 UIViewController (和子类) UINavigationController

    要使其工作,您必须:

    • 导航控制器 包含所有需要工具栏的视图控制器。
    • 设定 toolbarsItems 需要工具栏的视图控制器的属性。

    initWithNibName:bundle: 初始化器。例如:

    -(id)initWithNibName:(NSString*)name bundle:(NSBundle*)bundle;
    {
      self = [super initWithNibName:name bundle:bundle];
      if (self) {
        self.title = @"My Title";
        NSArray* toolbarItems = [NSArray arrayWithObjects:
            [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd 
                                                          target:self
                                                          action:@selector(addStuff:)],
            [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSearch 
                                                          target:self
                                                          action:@selector(searchStuff:)],
            nil];
        [toolbarItems makeObjectsPerformSelector:@selector(release)];
        self.toolbarItems = toolbarItems;
        self.navigationController.toolbarHidden = NO;
      }
      return self;
    }
    

    你也可以使用 setToolbarItems:animated: 而不是分配给 toolbarItems

    self.navigationController.toolbarHidden = NO;
    

    希望这有助于。。。

    - (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];
    
        }
    

    在Swift 3中:

    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
    }
