HarmonyOS app大图预览手势问题

swiper添加touch事件，非up场景，禁用swiper滑动功能，反之启用swiper滑动功能，如下：

Swiper() {
  ImageViewTouch({ model: $model, blockSwiper: $blockSwiper });
  ImageViewTouch({ model: $model1, blockSwiper: $blockSwiper });
  ImageViewTouch({ model: $model2, blockSwiper: $blockSwiper });
}
.onTouch((event?: TouchEvent) => {
  if(event){
    if (event.type === TouchType.Down) {
      this.eventType = 'Down'
    }
    if (event.type === TouchType.Up) {
      this.eventType = 'Up'
    }
    if (event.type === TouchType.Move) {
      this.eventType = 'Move'
    }
    this.text = 'TouchType:' + this.eventType + '\nDistance between touch point and touch element:\nx: '
      + event.touches[0].x + '\n' + 'y: ' + event.touches[0].y + '\nComponent globalPos:('
      + event.target.area.globalPosition.x + ',' + event.target.area.globalPosition.y + ')\nwidth:'
      + event.target.area.width + '\nheight:' + event.target.area.height
  }
})
.index(this.currentIndex)
.disableSwipe(this.eventType === 'Up' ? false : true)
