Swift:inputAccessoryView按钮未显示 [英] Swift: inputAccessoryView buttons are not showing

问题描述

以下是我向我的textView添加inputAccessoryView(带有完成按钮)的代码:

Following is my code for adding an inputAccessoryView (with a Done button on it) to my textView:

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"按钮将永远不会出现.我所得到的只是一个白色的附件栏.我在这里想念什么吗?

The Done button never appears. All I get is a white accessory bar. Am I missing anything here?

推荐答案

对我来说，我使用UINavigationBar创建附件视图是这样的:

For me I create the accessory view using UINavigationBar like this:

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
