你可以试着运行下Day3的工程，数据方面应该是有点问题，didSet里面的没有调用，还有TextField的Action事件拖动也是没有反应的。你试着运行看下就知道啦。

我这边没问题啊 你确定顶上topField有值吗?

恩，TopField刚才是忘记输入值了。还有一个疑问请教下：init方法设置的初始化值在Label上没有显示，Label的值是在拖拽的UISlider的时候才更新的。

没怎么看懂 因为拖拽的UISlider时候才赋值的

tipModel = TipModel.init(tipCount: "15%", topPrice: "$0.00", totalPrice: "0.00")
这句话中设置的数字，实际在关于Label初始化显示的时候，应该是没有起到作用吧。因为didSet方法应该是在拖拽UISlider时候赋值，然后才Label的值才更新的。
