如何实现一个GIF图显示指定次数

@Entry 
@Component 
struct Page2 { 
  @State isShowImg: boolean = true; 
  @State showTimes: number = 5; 
  private intervalId: number = 0; 
 
  aboutToAppear() { 
    this.showTimer() 
  } 
 
  showTimer() { 
    this.intervalId = setInterval(() => { 
      if (this.showTimes !== 0) { 
        this.isShowImg = !this.isShowImg; 
        this.showTimes -= 1; 
      } else { 
        clearInterval(this.intervalId); 
      } 
    }, 500) 
  } 
 
  aboutToDisappear() { 
    clearInterval(this.intervalId); 
  } 
 
  @Builder 
  showImg() { 
    Image('').width('100%').height(30) 
      .visibility(this.isShowImg ? Visibility.Visible : Visibility.Hidden) 
  } 
 
  build() { 
    Column() { 
      Text('hello world') 
        .width('80%') 
        .height(30) 
        .background(this.showImg()) 
        .onClick(() => { 
        }) 
    } 
    .width('100%') 
    .height('100%') 
  } 
}
