自定义键盘的核心思想
- 设置UITextFiled 的InputView
- 切换键盘的思路为重新设置UITextFiled 的InputView然后再调用textFiled?.reloadInputViews()
*剩下的就是按键的布局与代理设置了
swift版本采用策略模式实现，Objc版本使用常规模式实现
- 策略模式请参看另一编文章https://blog.csdn.net/d06110902002/article/details/75642548
swift版本的策略模式实现的角色划分如下：
- 策略管理类–键盘管理类KeyboardMgr
- 通用策略类–键盘基类KeyboardBaseView
- 具体的策略类–数字键盘、随机数字键盘、英文键盘
##具体的源码如下：
import UIKit
class KeyboardMgr: UIView {
var keyboard : KeyboardBaseView?
static let shareInstace = KeyboardMgr()
lazy var keyboardInstanceDict : [String : KeyboardBaseView] = Dictionary()
func setInputMethodKeyboard(keyboardview keyboard : KeyboardBaseView,
inputView textfiled:UITextField,
onKeyClickListener listener:OnKeyListener) {
self.keyboard = keyboard
self.keyboard?.createView(inputView: textfiled, addOnClickListener: listener)
keyboardInstanceDict[keyboard.description] = keyboard
}
}
- 策略基类源码：
import UIKit
@objc protocol OnKeyListener {
@objc optional func onClick(button view:UIButton);
/// 文本观察监听接口
/// - Parameters:
/// - view: 被观察的对象
/// - bStr: 观察之前的文本
/// - cStr: 当前u文本
/// - aStr: 编辑之后最终的文本
@objc optional func addTextWatch(button view:UIButton,
beforeText bStr:String?,
curText cStr:String?,
afterText aStr:String?);
}
class KeyboardBaseView: UIView {
var textFiled : UITextField?
let DELETE : NSInteger = 19;
let FINISH : NSInteger = 21;
let ABC : NSInteger = 22;
let CAPTIAL : NSInteger = 23;
let SWITCH_TYPE : NSInteger = 24;
let SEARCH : NSInteger = 25;
let SPACE : NSInteger = 98;

lazy var beforeText : String = String.init()
lazy var curText : String = String.init()
lazy var afterText : String = String.init()

}
public func createView(inputView targetView:UITextField,addOnClickListener listener:OnKeyListener){

targetView.inputView = self
self.onClickListener = listener
}
func createKey(titleTxt title:String,posX x:CGFloat, posY y:CGFloat, width w:CGFloat,hight h : CGFloat,forId id:NSInteger)->Void{

@objc func onClickListener(button:UIButton) {

}
