如何在Swift 3中设置editButtonItem标题

Question

我知道在Swift 2.2中很容易。像这样：

editButtonItem().title = "My Title"

但在Swift 3中，editButtonItem成为UIViewController的属性。并且UIBarButtonItem不再拥有标题。所以这不起作用：

editButtonItem.title = "My Title" // doesn't work

请帮帮我！谢谢！

1. 这可能对您有帮助！

   let navigationBar = navigationController!.navigationBar
   navigationBar.tintColor = UIColor.blueColor()
   
   let leftButton =  UIBarButtonItem(title: "Left Button", style: UIBarButtonItemStyle.Plain, target: self, action: nil)
   navigationItem.leftBarButtonItem = leftButton
