xcode - How can I add a Toolbar to a UITableViewController

问题

I have a little problem. I wanna add a Toolbar in the button of my UITableViewController, but it doesn't work. Why?

If your UITableViewController is embedded in UINavigationController, the navigation controller comes with a toolbar. You wouldn't need to add your own.

The navigation controller's toolbar is hidden by default. You can enable it by:

• Checking the Shows toolbar option in the navigation controller Interface Builder attribute inspector pane, or

• Setting the toolbar visibility in code:

  [self.navigationController setToolbarHidden:NO animated:YES];
  

Enabling the toolbar in Storyboard has the advantage of letting you drag and drop items onto it using Interface Builder. You can also add toolbar items in code, by calling setToolbarItems:
