Question

以下是我的textView上添加inputAccessoryView（带有Done按钮）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吧。我在这里错过了什么吗？

Answer 1

对我来说，我使用UINavigationBar创建配件视图，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

Answer 2

1）加入自我？ self.messageView.inputAccessoryView = keyboardButtonView

2）您应该可以删除此行： doneButton.possibleTitles = [＆＃34;完成＆＃34;] 并添加（标题：＆＃34;完成＆＃34;，...）到它上面的一行。

3）我有类似的代码，它可能并不重要，但是，您可以添加： keyboardButtonView.barStyle = UIBarStyle.Default

Swift：inputAccessoryView按钮未显示
