Question

我使用JHChainableAnimations来增大（缩放）视图设置新值，然后再将视图缩小（缩放）到原始大小。

我试着这样做：

    var isGrowing = true
    self.badgeView?.transformScale()(2).animate()(3)
      self.badgeView?.animationCompletion = {
        if isGrowing {
          isGrowing = false
          self.badgeView?.badgeText = "\(self.selectionCounter)"
          self.badgeView?.transformScale()(1).animate()(3)
        }
    }

但它不会那样工作。我该如何解决这个问题？

在JHChainableAnimations中的示例中，您必须在开始动画之前设置animationCompletion，而animationCompletion类型必须是JHAnimationCompletion

var isGrowing = true
self.badgeView?.animationCompletion = JHAnimationCompletion(){
    if isGrowing {
      isGrowing = false
      self.badgeView?.badgeText = "\(self.selectionCounter)"
      self.badgeView?.transformScale()(0.5).animate()(3)
    }
}
self.badgeView?.transformScale()(2).animate()(3)

增长视图执行动作和缩小视图
