Because i don't want the UITextField/UITextViewand the control to be in UITextView/UITextField. I am going to add inputAccessoryViewon the keyboard is UITextView. when the user touches the UITextviewin the keyboard inputViewthe actual process will be continue.
因为我不希望UITextField/UITextView和控件位于UITextView/ 中UITextField。我要inputAccessoryView在键盘上添加的是UITextView。当用户触摸UITextview键盘中inputView的 时，实际过程将继续。

For anyone, who wants to show keyboard without UITextField/UITextViewfor some reasons, could easily extend some view, which requires text input by implementing UIKeyInputprotocol and canBecomeFirstRespondermethod.
对于出于某些原因想要在没有UITextField/UITextView的情况下显示键盘的任何人，可以轻松扩展一些视图，这需要通过实现UIKeyInput协议和canBecomeFirstResponder方法来输入文本。

See the documentation for doing that here:
请参阅此处的文档：
All you need to do is have your view implement UIKeyInputand call [inputView becomeFirstResponder]when the view is touched. Your view also needs to implement canBecomeFirstResponderand return YES.
您需要做的就是让您的视图实现UIKeyInput并[inputView becomeFirstResponder]在触摸视图时调用。您的视图还需要实现canBecomeFirstResponder并返回 YES。

You can also try this:
你也可以试试这个：
UIKeyboard *keyboard = [[[UIKeyboard alloc] initWithFrame: CGRectMake(0.0f, contentRect.size.height - 216.0f, contentRect.size.width, 216.0f)] autorelease];
[keyboard setReturnKeyEnabled:NO];
[keyboard setTapDelegate:editingTextView];
[inputView addSubview:keyboard];

In xcode simulator:
在 xcode 模拟器中：
Sometimes the keyboard wont show because the software keyboard is off. Go to hardware -> Keyboard -> toggle keyboard
有时键盘不会显示，因为软键盘已关闭。转到硬件 -> 键盘 -> 切换键盘

Make a View, Label or what ever to conform to UIKeyInput. In this case a UIView
制作一个视图、标签或任何符合 UIKeyInput 的东西。在这种情况下，一个 UIView
Sub class a UIView:
子类 UIView：
import UIKit
class KeyInputView: UIView {
var _inputView: UIView?
override var canBecomeFirstResponder: Bool { return true }
override var canResignFirstResponder: Bool { return true }
override var inputView: UIView? {
set { _inputView = newValue }
get { return _inputView }
}
}
// MARK: - UIKeyInput
//Modify if need more functionality
extension KeyInputView: UIKeyInput {
var hasText: Bool { return false }
func insertText(_ text: String) {}
func deleteBackward() {}
}
Setup your View, in this case with a picker (in viewDidLoad or where ever)
设置您的视图，在这种情况下使用选择器（在 viewDidLoad 或任何地方）
let languangePicker = UIPickerView()
languangePicker.dataSource = self
languangePicker.delegate = self
keyInputView.inputView = languangePicker
To show:
显示：
keyInputView.becomeFirstResponder()
To hide:
隐藏：
keyInputView.resignFirstResponder()
Set picker data, from datasource (compiler force u to do it)
从数据源设置选择器数据（编译器强制你这样做）
Grab data picker events from delegate
从委托中获取数据选择器事件
