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按钮以获取textView。请告诉我该怎么做？

我想实现与上述键盘类似的东西

Answer 1

它可以使用故事板完成：

1. 将UITextField添加到UIViewController视图。
2. 在UIViewController的第一级添加UIToolbar
3. 将UIBarButtonItem添加到UIToolbar中。
4. 使用IBOutlet将UItoolbar连接到代码。
5. 使用IBAction将UIBarButtonItem连接到代码（如didClick）。
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应为：textField.inputAccessoryView = toolbar并返回true。

Answer 2

希望这有帮助:)

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];
}

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)
}

这个解决方案适用于Swift3 / 4

将此行添加到项目中作为扩展您的问题已解决。

  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()
        }

    }

添加UIToolBar作为自定义视图，其中包含UIBarButtonItem作为Done按钮。

这是将Done按钮添加到任何类型键盘的更安全，更清晰的方法。创建UIToolBar为其添加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)
  }

使用自定义类解决Swift 4和Swift 5的问题。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()
    }
}

Ramis的答案是允许使用Storyboard创建键盘配件视图是一个很好的策略。毕竟是2017年！ （对不起，但我没有足够的积分来支持你。）

让我在答案中加一点（保持在SO规则范围内）。我有一个包含多个textFields的视图。在实现了Ramis的每个步骤之后，我以这种方式将accessoryView附加到所有textField：

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

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

这个解决方案适用于Swift 4

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)
}
