+# 输入法框架changeLog
+
+## cl.inputmethod_frameworks.1 API错误信息返回方式变更
+
+下列模块内部接口使用业务逻辑返回值表示错误信息，不符合OpenHarmony接口错误码规范。在API9进行变更。
+
+ - 输入法框架模块：系统接口，@ohos.inputmethod.d.ts
+
+ - 输入法服务模块：系统接口，@ohos.inputmethodengine.d.ts
+
+ - 输入法ExtentionAbility模块：系统接口，@ohos.inputmethodextensionability.d.ts
+
+ - 输入法ExtentionContext模块：系统接口，@ohos.inputmethodextensioncontext.d.ts
+
+ - 输入法子类型模块：系统接口，@ohos.inputMethodSubtype.d.ts
+ 
+异步接口：通过AsyncCallback或Promise的error对象返回错误信息。
+
+同步接口：通过抛出异常的方式返回错误信息。
+
+**变更影响**
+
+基于此前版本开发的应用，需适配接口的错误信息返回方式，否则会影响原有业务逻辑。
+
+**关键接口/组件变更**
+
+在以下接口增加错误码处理：
+  - getSetting(): InputMethodSetting;
+  - getController(): InputMethodController;
+  - switchInputMethod(target: InputMethodProperty, callback: AsyncCallback<boolean>): void;
+  - switchInputMethod(target: InputMethodProperty): Promise<boolean>;
+  - switchCurrentInputMethodSubtype(target: InputMethodSubtype, callback: AsyncCallback<boolean>): void;
+  - switchCurrentInputMethodSubtype(target: InputMethodSubtype): Promise<boolean>;
+  - switchCurrentInputMethodAndSubtype(inputMethodProperty: InputMethodProperty, inputMethodSubtype: InputMethodSubtype, callback: AsyncCallback<boolean>): void;
+  - switchCurrentInputMethodAndSubtype(inputMethodProperty: InputMethodProperty, inputMethodSubtype: InputMethodSubtype): Promise<boolean>;
+  - listInputMethodSubtype(inputMethodProperty: InputMethodProperty, callback: AsyncCallback<Array<InputMethodSubtype>>): void;
+  - listInputMethodSubtype(inputMethodProperty: InputMethodProperty): Promise<Array<InputMethodSubtype>>;
+  - listCurrentInputMethodSubtype(callback: AsyncCallback<Array<InputMethodSubtype>>): void;
+  - listCurrentInputMethodSubtype(): Promise<Array<InputMethodSubtype>>;
+  - getInputMethods(enable: boolean, callback: AsyncCallback<Array<InputMethodProperty>>): void;
+  - getInputMethods(enable: boolean): Promise<Array<InputMethodProperty>>;
+  - showOptionalInputMethods(callback: AsyncCallback<boolean>): void;
+  - showOptionalInputMethods(): Promise<boolean>;
+  - stopInputSession(callback: AsyncCallback<boolean>): void;
+  - stopInputSession(): Promise<boolean>;
+  - showSoftKeyboard(callback: AsyncCallback<void>): void;
+  - showSoftKeyboard():Promise<void>;
+  - hideSoftKeyboard(callback: AsyncCallback<void>): void;
+  - hideSoftKeyboard():Promise<void>;
+  - hide(callback: AsyncCallback<void>): void;
+  - hide(): Promise<void>;
+  - onCreate(want: Want): void;
+  - onDestroy(): void;
+  InputClient 接口下：
+  - sendKeyFunction(action: number, callback: AsyncCallback<boolean>): void;
+  - sendKeyFunction(action: number): Promise<boolean>;
+  - deleteForward(length: number, callback: AsyncCallback<boolean>): void;
+  - deleteForward(length: number): Promise<boolean>;
+  - deleteBackward(length: number, callback: AsyncCallback<boolean>): void;
+  - deleteBackward(length: number): Promise<boolean>;
+  - insertText(text: string, callback: AsyncCallback<boolean>): void;
+  - insertText(text: string): Promise<boolean>;
+  - getForward(length: number, callback: AsyncCallback<string>): void;
+  - getForward(length: number): Promise<string>;
+  - getBackward(length: number, callback: AsyncCallback<string>): void;
+  - getBackward(length: number): Promise<string>;
+  - getEditorAttribute(callback: AsyncCallback<EditorAttribute>): void;
+  - getEditorAttribute(): Promise<EditorAttribute>;
+  - moveCursor(direction: number, callback: AsyncCallback<void>): void;
+  - moveCursor(direction: number): Promise<void>;
+  InputMethodExtensionAbility 类下：
+  - onCreate(want: Want): void;
+  - onDestroy(): void;
+  
+**适配指导**
+
+异步接口以showOptionalInputMethods为例，示例代码如下：
+
+callback回调：
+
+```js
+import inputMethod from '@ohos.inputmethod';
+let inputMethodSetting = inputMethod.getSetting();
+try {
+    inputMethodSetting.showOptionalInputMethods((err, data) => {
+        if (err !== undefined) {
+            console.error('Failed to showOptionalInputMethods: ' + JSON.stringify(err));
+            return;
+        }
+        console.info('Succeeded in showing optionalInputMethods.');
+    });
+} catch (err) {
+    console.error('Failed to showOptionalInputMethods: ' + JSON.stringify(err));
+}
+```
+
+Promise回调：
+
+```js
+import inputMethod from '@ohos.inputmethod';
+let inputMethodSetting = inputMethod.getSetting();
+inputMethodSetting.showOptionalInputMethods().then((data) => {
+    console.info('Succeeded in showing optionalInputMethods.');
+}).catch((err) => {
+    console.error('Failed to showOptionalInputMethods: ' + JSON.stringify(err));
+})
+```
+
+## cl.inputmethod_frameworks.2 API部分接口废弃
+
+以下接口标记废除：
+  - getInputMethodSetting(): InputMethodSetting;
+  - getInputMethodController(): InputMethodController;
+  - listInputMethod(callback: AsyncCallback<Array<InputMethodProperty>>): void;
+  - listInputMethod(): Promise<Array<InputMethodProperty>>;
+  - displayOptionalInputMethod(callback: AsyncCallback<void>): void;
+  - displayOptionalInputMethod(): Promise<void>;
+  - stopInput(callback: AsyncCallback<boolean>): void;
+  - stopInput(): Promise<boolean>;
+  interface InputMethodProperty：
+    - readonly packageName: string;
+	- readonly methodId: string;
+  - getInputMethodEngine(): InputMethodEngine;
+  - createKeyboardDelegate(): KeyboardDelegate;
+  - hideKeyboard(callback: AsyncCallback<void>): void;
+  - hideKeyboard(): Promise<void>;
+
+替代接口如下:
+  - getSetting(): InputMethodSetting;
+  - getController(): InputMethodController;
+  - getInputMethods(enable: boolean, callback: AsyncCallback<Array<InputMethodProperty>>): void;
+  - getInputMethods(enable: boolean): Promise<Array<InputMethodProperty>>;
+  - showOptionalInputMethods(callback: AsyncCallback<boolean>): void;
+  - showOptionalInputMethods(): Promise<boolean>;
+  - stopInputSession(callback: AsyncCallback<boolean>): void;
+  - stopInputSession(): Promise<boolean>;
+  interface InputMethodProperty：
+    - readonly name: string;
+	- readonly id: string;
+  - getInputMethodAbility(): InputMethodAbility;
+  - getKeyboardDelegate(): KeyboardDelegate;
+  - hide(callback: AsyncCallback<void>): void;
+  - hide(): Promise<void>;
+  
+**特别注意：**
+    使用getInputMethodAbility()接口获取到InputMethodAbility对象，代替使用getInputMethodEngine()接口获取InputMethodEngine对象。
+	使用InputMethodAbility中的方法，不要再使用InputMethodEngine中的方法。
+	使用InputMethodAbility中的on('inputStart')方法，获取到KeyboardController实例与InputClient实例，不要再使用InputMethodEngine中的on('inputStart')方法去获取TextInputClient实例。
+之前：
+
+```js
+inputMethodEngine.getInputMethodEngine().on('inputStart', (kbController, textClient) => {
+    let keyboardController = kbController;
+    let textInputClient = textClient;  // 获取到TextInputClient实例
+});
+```
+
+之后：
+```js
+inputMethodEngine.getInputMethodAbility().on('inputStart', (kbController, client) => {
+    let keyboardController = kbController;
+    let inputClient = client;  // // 获取到InputClient实例
+});
+```
+
+## cl.inputmethod_frameworks.3 API部分接口变更
+
+变更前：
+  - listInputMethod(enable: boolean, callback: AsyncCallback<Array<InputMethodProperty>>): void;
+  - listInputMethod(enable: boolean): Promise<Array<InputMethodProperty>>;
+  - terminateSelf(callback: AsyncCallback<void>): void;
+  - terminateSelf(): Promise<void>;
+  
+变更后：
+  - getInputMethods(enable: boolean, callback: AsyncCallback<Array<InputMethodProperty>>): void;

+  
+删除API9接口：

+  - startAbility(want: Want, options?: StartOptions): Promise<void>;
+

+  - interface InputMethodProperty：
+    - readonly label?: string;
+	- readonly icon?: string;
+	- readonly iconId?: number;
+	- extra: object;
+	
+  - interface InputMethodAbility：
+    - on(type: 'setSubtype', callback: (inputMethodSubtype: InputMethodSubtype) => void): void;
