ios - 扩大 View 执行操作和缩小 View

Question

我使用 JHChainableAnimations增大(缩放) View 设置一个新值，然后再次将 View 缩小(缩放)到其原始大小。

我尝试过:

    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)
        }
    }

但是这样不行。我该如何解决这个问题？

来自 JHChainableAnimations 中的示例你必须在开始动画之前设置 animationCompletion 并且 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)
