Textinput是否支持自动聚焦？

@Entry  
@Component  
struct Index {  
  @State message: string = '123456';  
  controller: TextInputController = new TextInputController()  
  private inputId:string = 'ceshi';  
  
  build() {  
    Column() {  
      TextInput({ text: this.message, placeholder: 'input your word...', controller: this.controller })  
        .placeholderColor(Color.Grey)  
        .placeholderFont({ size: 14, weight: 400 })  
        .caretColor(Color.Blue)  
        .width('95%')  
        .height(40)  
        .margin(20)  
        .fontSize(14)  
        .fontColor(Color.Black)  
        .id(this.inputId)  
        .onChange((value: string) => {  
          this.message = value  
        })  
      Button('自动聚焦').onClick((event: ClickEvent) => {  
        this.controller.caretPosition(this.message.length)  
        focusControl.requestFocus(this.inputId)  
      })  
    }  
    .width('100%')  
  }  
}
