以下是我将 inputAccessoryView（上面带有完成按钮）添加到我的 textView 的代码：

let keyboardButtonView = UIToolbar()
keyboardButtonView.sizeToFit()
let doneButton = UIBarButtonItem(image: nil, style: .Done, target: self, action: "closeMessageViewKeyboard")
doneButton.possibleTitles = ["Done"]
var toolbarButtons = NSMutableArray()
toolbarButtons.addObject(doneButton)
keyboardButtonView.items = toolbarButtons as [AnyObject]
messageView.inputAccessoryView = keyboardButtonView

完成按钮永远不会出现。我得到的只是一个白色的配件条。我在这里错过了什么吗？

对我来说，我使用 UINavigationBar 创建附件视图，如下所示：

let navBar = UINavigationBar(frame: CGRectMake(0, 0, viewWidth, 44))
navBar.barStyle = UIBarStyle.BlackTranslucent;
navBar.backgroundColor = UIColor.blackColor();
navBar.alpha = 0.9;
//replace viewWidth with view controller width
let navItem = UINavigationItem()
let doneButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "closeMessageViewKeyboard")
navItem.rightBarButtonItem = doneButton

navBar.pushNavigationItem(navItem, animated: false)

messageView.inputAccessoryView = navBar

1）添加自我？self.messageView.inputAccessoryView = 键盘按钮视图

2）您应该能够删除此行：doneButton.possibleTitles = ["Done"] 并将 (title: "done",...) 添加到它上面的行。

3）我有类似的代码，它可能没关系，但是，你可以添加：keyboardButtonView.barStyle = UIBarStyle.Default
