scrollview嵌套两个tableview，滑动卡顿。
先描述一下情景，一个父VC两个子VC，在父VC的view上添加了一个scrollview，然后在scrollview上添加了两个子VC上的tableview。
tableview放到两个子VC里主要是为了网络处理方便，但是现在滑动的时候特别卡，FPS降的很低，卡的厉害了就崩溃了，这个该怎样处理，有知道的吗？
PS:滑动手势不冲突。
小伙看你根骨奇佳，潜力无限，来学PHP伐。
Please learn how to use UIPageViewController. In addition, there are many mature implementations of the NetEase News control on github, so there is no need to implement it yourself.
Use time profile to see where there are time-consuming operations.
I can only say that the idea is fine, the problem should lie in your specific implementation.
