如何在IOS键盘顶部的键盘上添加完成按钮？

Question

我想在 iOS 右侧的键盘顶部添加 Done 按钮作为 textView。请告诉我该怎么做？

我想实现类似于上面键盘的东西

Answer 1

希望有帮助:)

UIToolbar* keyboardToolbar = [[UIToolbar alloc] init];
[keyboardToolbar sizeToFit];
UIBarButtonItem *flexBarButton = [[UIBarButtonItem alloc]
                                  initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
                                  target:nil action:nil];
UIBarButtonItem *doneBarButton = [[UIBarButtonItem alloc]
                                  initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                  target:self action:@selector(yourTextViewDoneButtonPressed)];
keyboardToolbar.items = @[flexBarButton, doneBarButton];
self.yourTextView.inputAccessoryView = keyboardToolbar;

然后添加 yourTextViewDoneButtonPressed 方法

-(void)yourTextViewDoneButtonPressed
{
    [self.yourTextView resignFirstResponder];
}

Answer 2

可以使用故事板来完成：

1. 将 UITextField 添加到 UIViewController 视图。
2. 在一级UIViewController中添加UIToolbar
3. 将 UIBarButtonItem 添加到 UIToolbar。
4. 使用 IBOutlet 将 UItoolbar 连接到代码。
5. 使用 IBAction 将 UIBarButtonItem 连接到代码（与 didClick 一样）。
6. 使 UITextField 将委托给 UIViewController。
7. 在didClick函数结束编辑(view.endEditing(true))
8. 在委托函数中 textFieldShouldBeginEditing 应该是：textField.inputAccessoryView = toolbar并返回true。李>

斯威夫特 3：

func setDoneOnKeyboard() {
    let keyboardToolbar = UIToolbar()
    keyboardToolbar.sizeToFit()
    let flexBarButton = UIBarButtonItem(barButtonSystemItem: .flexibleSpace, target: nil, action: nil)
    let doneBarButton = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(InsertStatusVC.dismissKeyboard))
    keyboardToolbar.items = [flexBarButton, doneBarButton]
    self.fullNameTextField.inputAccessoryView = keyboardToolbar
}

@objc func dismissKeyboard() {
    view.endEditing(true)
}

此解决方案适用于 Swift3/4

将此行作为扩展添加到您的项目中 你的问题解决了。

  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
        }

        @objc func doneButtonAction() {
            self.resignFirstResponder()
        }

    }

Swift 4 和 Swift 5 使用自定义类的解决方案。您可以在 Storyboard 和 .xib 文件中使用此类。

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()
    }
}

Answer 6

Swift 4 的这个解决方案

override func viewDidLoad() {
   super.viewDidLoad()
   //init toolbar
   let toolbar:UIToolbar = UIToolbar(frame: CGRect(x: 0, y: 0,  width: self.view.frame.size.width, height: 30))
   //create left side empty space so that done button set on right side
   let flexSpace = UIBarButtonItem(barButtonSystemItem:    .flexibleSpace, target: nil, action: nil)
   let doneBtn: UIBarButtonItem = UIBarButtonItem(title: “Done”, style: .done, target: self, action: Selector(“doneButtonAction”))
   toolbar.setItems([flexSpace, doneBtn], animated: false)
   toolbar.sizeToFit()
   //setting toolbar as inputAccessoryView
   self.textField1.inputAccessoryView = toolbar
   self.textField2.inputAccessoryView = toolbar
}
func doneButtonAction() {
   self.view.endEditing(true)
}

Answer 7

将 UIToolBar 添加为自定义视图，其中包含 UIBarButtonItem 作为完成按钮。

这是将完成按钮添加到任何类型键盘的更安全、更简洁的方法。创建 UIToolBar 添加 Done Button 并设置任何 UITextField 或 UITextView 的 inputAccessoryView。 ]; }

SWIFT 3

var ViewForDoneButtonOnKeyboard = UIToolbar()
ViewForDoneButtonOnKeyboard.sizeToFit()
var btnDoneOnKeyboard = UIBarButtonItem(title: "Done", style: .bordered, target: self, action: #selector(self.doneBtnFromKeyboardClicked))
ViewForDoneButtonOnKeyboard.items = [btnDoneOnKeyboard]
myTextField.inputAccessoryView = ViewForDoneButtonOnKeyboard

功能

  @IBAction func doneBtnfromKeyboardClicked (sender: Any) {
     print("Done Button Clicked.")
    //Hide Keyboard by endEditing or Anything you want.
    self.view.endEditing(true)
  }

Answer 8

Ramis 的回答是允许使用情节提要创建键盘附件视图，这是一个很好的策略。毕竟是2017年！ （抱歉，我没有足够的积分来支持你。）

让我补充一点答案（以遵守 SO 规则）。我有多个文本字段的视图。在执行了 Ramis 的每个步骤后，我以这种方式将附件视图附加到所有文本字段：

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
_activeTextField = textField;
[_activeTextField setInputAccessoryView:_iboKeyboardTools];
}

与在代码中实现所有这些相比，这太容易了！只需在 Storyboard 中构建附件视图，然后一次又一次地附加它！
