@Entry  
@Component  
struct ActionSheetExample {  
  build() {  
    Flex({ direction: FlexDirection.Column, alignItems: ItemAlign.Center, justifyContent: FlexAlign.Center }) {  
      Button('Click to Show ActionSheet')  
        .onClick(() => {  
          ActionSheet.show({  
            title: 'ActionSheet title',  
            message: 'message',  
            autoCancel: true,  
            confirm: {

                action: () => {  
                  //方案一：添加占位符 '/n'  
                  console.log('apples'+'/n')  
                }

                //方案二：导入图片，设置图片宽高撑出高度  
                icon:$r('app.media.food'),
