创建后在UITextView的inputAccessoryView中更改UIBarButtonItem的按钮标题？

Question

我在 viewDidLoad 中为 UITextView 创建了一个 inputAccessoryView:

var keyBoardToolBar: UIToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.frame.size.width, 50)) keyBoardToolBar.barStyle = UIBarStyle.Default

var firstButton: UIBarButtonItem = UIBarButtonItem(title: "firstButton", style: UIBarButtonItemStyle.Plain, target: self, action: Selector("firstButtonAction"))

var flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)

var done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("doneButtonAction"))

var items = NSMutableArray()

items.addObject(firstButton)
items.addObject(flexSpace)
items.addObject(done)

keyBoardToolBar.items = items as [AnyObject]
keyBoardToolBar.sizeToFit()

self.tv.inputAccessoryView = keyBoardToolBar

我想在其他功能中更改 firstButton 的按钮文本（在 viewDidLoad 之后）。那我该怎么办？谢谢！

Answer 1

我 var firstButton: UIBarButtonItem 就在 viewDidLoad 之前的 class 内，并更改它的标题使用 firstButton.title。 :)
