如何添加＆＃34;完成＆＃34;使用Swift在IOS 8中按键到Numpad？
使用默认键盘工作正常，但我无法使用小键盘。
有什么想法吗？

据我所知，你不能在键盘部分添加完成按钮;您已向inputAccessoryView或UITextField添加了UITextView（如果您正在使用的话）。
检查documentation for more info。
修改：检查this question for an example如何执行此操作。
修改2 ：类似example in Swift。

override func viewDidLoad()
{
super.viewDidLoad()
//--- add UIToolBar on keyboard and Done button on UIToolBar ---//
self.addDoneButtonOnKeyboard()
}
//--- *** ---//
func addDoneButtonOnKeyboard()
{
var doneToolbar: UIToolbar = UIToolbar(frame: CGRectMake(0, 0, 320, 50))
doneToolbar.barStyle = UIBarStyle.BlackTranslucent
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(flexSpace)
items.addObject(done)
doneToolbar.items = items
doneToolbar.sizeToFit()
self.textView.inputAccessoryView = doneToolbar
self.textField.inputAccessoryView = doneToolbar
}
func doneButtonAction()
{
self.textViewDescription.resignFirstResponder()
}
Swift 4.2
func addDoneButtonOnKeyboard(){
let doneToolbar: UIToolbar = UIToolbar(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
doneToolbar.barStyle = .default
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))
let items = [flexSpace, done]
doneToolbar.items = items
doneToolbar.sizeToFit()
txtMobileNumber.inputAccessoryView = doneToolbar
}
@objc func doneButtonAction(){
txtMobileNumber.resignFirstResponder()

Swift-3版本（ Marko的解决方案 - 对我有用）
（在我的情况下，我将UITextField标识为textfield ）
func addDoneButtonOnKeyboard() {
let doneToolbar: UIToolbar = UIToolbar(frame: CGRect(x: 0, y: 0, width: 320, height: 50))
doneToolbar.barStyle = UIBarStyle.default
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.flexibleSpace, target: nil, action: nil)
let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.done, target: self, action: #selector(ViewController.doneButtonAction))
var items = [UIBarButtonItem]()
items.append(flexSpace)
items.append(done)
doneToolbar.items = items
doneToolbar.sizeToFit()
self.textfield.inputAccessoryView = doneToolbar
}
func doneButtonAction() {
self.textfield.resignFirstResponder()
}

使用
@IBInpectable和扩展程序Swift 3 解决方案。对于项目中的每个UITextField，下拉列表将显示在Interface Builder的Attribute Inspector下。
extension UITextField{
@IBInspectable var doneAccessory: Bool{
get{
return self.doneAccessory
}
set (hasDone) {
if hasDone{
addDoneButtonOnKeyboard()
}
}
}
func addDoneButtonOnKeyboard()
{
let doneToolbar: UIToolbar = UIToolbar(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
doneToolbar.barStyle = .default
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))
let items = [flexSpace, done]
doneToolbar.items = items
doneToolbar.sizeToFit()
self.inputAccessoryView = doneToolbar
}
func doneButtonAction()
{
self.resignFirstResponder()
}
}

您可以将带有完成按钮的工具栏添加到键盘。 parameterValues textfield属性可用于设置此工具栏。

答案 4 :(得分：5)
如果您的Done按钮应该只关闭数字键盘，那么最简单的版本就是将resignFirstResponder称为选择器，如下所示：
UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: textField, action: #selector(UITextField.resignFirstResponder))
此代码适用于iOS9和Swift 2，我在我的应用程序中使用它：
func addDoneButtonOnNumpad(textField: UITextField) {
let keypadToolbar: UIToolbar = UIToolbar()
// add a done button to the numberpad
keypadToolbar.items=[
UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: textField, action: #selector(UITextField.resignFirstResponder)),
UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: self, action: nil)
]
keypadToolbar.sizeToFit()
// add a toolbar with a done button above the number pad
textField.inputAccessoryView = keypadToolbar
}
答案 5 :(得分：3)
首先让我告诉你一件事，你可以在你的默认KeyBoard上添加一个完成按钮。实际上今天我刚刚解决了这个问题并解决了。现成的代码，只需将它放在.swift类上。我正在使用Xcode 7并使用iPad Retina（ios 9）进行测试。
无论如何，这里不再谈论代码了。
//Creating an outlet for the textfield
@IBOutlet weak var outletTextFieldTime: UITextField!
//Adding the protocol of UITextFieldDelegate
class ReservationClass: UIViewController, UITextFieldDelegate {
func textFieldShouldBeginEditing(textField: UITextField) -> Bool {
//Making A toolbar
let keyboardDoneButtonShow = UIToolbar(frame: CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height/17))
//Setting the style for the toolbar
keyboardDoneButtonShow.barStyle = UIBarStyle .BlackTranslucent
//Making the done button and calling the textFieldShouldReturn native method for hidding the keyboard.
let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("textFieldShouldReturn:"))
//Calculating the flexible Space.
let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
//Setting the color of the button.
item.tintColor = UIColor .yellowColor()
//Making an object using the button and space for the toolbar
let toolbarButton = [flexSpace,doneButton]
//Adding the object for toolbar to the toolbar itself
keyboardDoneButtonShow.setItems(toolbarButton, animated: false)
//Now adding the complete thing against the desired textfield
outletTextFieldTime.inputAccessoryView = keyboardDoneButtonShow
return true
}
//Function for hidding the keyboard.
func textFieldShouldReturn(textField: UITextField) -> Bool {
self.view.endEditing(true)
return false
}
}
这给了我解决方案......
还有一件事我想告诉你，这是我在最近的项目中使用的工作解决方案。我发布了这个，因为没有可用的解决方案。工作守则和承诺的解释。
编辑： -
让它变得更专业......如果你遵循上面的代码那么它也会给你工作的解决方案，但在这里我试图让它更专业。请注意代码MOD。我把之前未使用的代码留下了引号。
变化..
- 创建单个按钮对象
- 将其设置为工具栏
- 缩小先前创建的工具栏的大小
-
使用FlexSpace和NegativeSpace将自定义按钮定位在屏幕左侧。
func textFieldShouldBeginEditing(textField: UITextField) -> Bool { let keyboardDoneButtonShow = UIToolbar(frame: CGRectMake(200,200, self.view.frame.size.width,30)) // self.view.frame.size.height/17 keyboardDoneButtonShow.barStyle = UIBarStyle .BlackTranslucent let button: UIButton = UIButton() button.frame = CGRectMake(0, 0, 65, 20) button.setTitle("Done", forState: UIControlState .Normal) button.addTarget(self, action: Selector("textFieldShouldReturn:"), forControlEvents: UIControlEvents .TouchUpInside) button.backgroundColor = UIColor .clearColor() // let doneButton = UIBarButtonItem(title: "Done", style: UIBarButtonItemStyle.Done, target: self, action: Selector("textFieldShouldReturn:")) let doneButton: UIBarButtonItem = UIBarButtonItem() doneButton.customView = button let negativeSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FixedSpace, target: nil, action: nil) negativeSpace.width = -10.0 let flexSpace = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil) //doneButton.tintColor = UIColor .yellowColor() let toolbarButton = [flexSpace,doneButton,negativeSpace] keyboardDoneButtonShow.setItems(toolbarButton, animated: false) outletTextFieldTime.inputAccessoryView = keyboardDoneButtonShow return true }
现在给我以下内容......此外，请尝试匹配图片并找到更改。
感谢。
希望这有帮助。对不起，答案很长。
答案 6 :(得分：3)
因为以上答案在Xcode 11中都是较早的，并且像UIToolbar()这样的初始toolBar每次像您运行的here一样都会在控制台上施加破坏性约束，因此请使用
UIToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 35))代替
示例代码
let toolBar = UIToolbar(frame: CGRect(x: 0, y: 0, width: view.frame.size.width, height: 35))
toolBar.barStyle = .default
toolBar.sizeToFit()
// Adding Button ToolBar
let doneButton = UIBarButtonItem(title: "Done", style: .plain, target: self, action: #selector(doneButtonTapped))
toolBar.items = [doneButton]
toolBar.isUserInteractionEnabled = true
textField.inputAccessoryView = toolBar
答案 7 :(得分：2)
根据Marko Nikolovski的回答
这是客观的答案：
- (void)ViewDidLoad {
[self addDoneButtonOnKeyboard];
}
- (void)addDoneButtonOnKeyboard {
UIToolbar *toolBarbutton = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 50)];
toolBarbutton.barStyle = UIBarStyleBlackTranslucent;
UIBarButtonItem *barBtnItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *done = [[UIBarButtonItem alloc] initWithTitle:@"Done" style:UIBarButtonItemStyleDone target:self action:@selector(doneButtonAction)];
NSMutableArray *items = [[NSMutableArray alloc] init];
[items addObject:barBtnItem];
[items addObject:done];
toolBarbutton.items = items;
[toolBarbutton sizeToFit];
self.timeoutTextField.inputAccessoryView = toolBarbutton;
}
- (void)doneButtonAction {
[self.view endEditing:YES];
}

我将使用一个名为IQKeyboardManagerSwift的库。

您可以创建一个自定义类。我正在使用 Swift 4 ：
class UITextFieldWithDoneButton: UITextField {
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.addDoneButtonOnKeyboard()
}
fileprivate func addDoneButtonOnKeyboard() {
let doneToolbar: UIToolbar = UIToolbar(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width, height: 50))
doneToolbar.barStyle = .default
let flexSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
let done: UIBarButtonItem = UIBarButtonItem(title: "Done", style: .done, target: self, action: #selector(self.doneButtonAction))
let items = [flexSpace, done]
doneToolbar.items = items
doneToolbar.sizeToFit()
self.inputAccessoryView = doneToolbar
}
@objc fileprivate func doneButtonAction() {
self.resignFirstResponder()
}
}
答案 10 :(得分：0)
我能找到的最简单的解决方案-与 Swift 4.2 一起使用-希望这会有所帮助:)
extension UITextField {
func addDoneButtonOnKeyboard() {
let keyboardToolbar = UIToolbar()
keyboardToolbar.sizeToFit()
let flexibleSpace = UIBarButtonItem(barButtonSystemItem: .flexibleSpace,
target: nil, action: nil)
let doneButton = UIBarButtonItem(barButtonSystemItem: .done,
target: self, action: #selector(resignFirstResponder))
keyboardToolbar.items = [flexibleSpace, doneButton]
self.inputAccessoryView = keyboardToolbar
}
}
然后，您可以在textFieldDidEndEditing委托方法中处理已完成的操作，或者仅向扩展名添加自定义方法，然后在doneButton的选择器中进行设置。

在任何键盘上添加“完成”按钮的简单方法是添加通用库
在应用程序的appdelegate中添加以下代码（_应用程序：UIApplication，didFinishLaunchingWithOptions。
IQKeyboardManager.shared.enable = true
IQKeyboardManager.shared.enableAutoToolbar = true
IQKeyboardManager.shared.keyboardDistanceFromTextField = 15
IQKeyboardManager.shared.shouldResignOnTouchOutside = true
