由于第一次使用TABAnimated，遇到了很多问题，首先就是对xib支持不怎么友好。

如图UI设计卡片的式样

Xib中这样布局

加载中骨架屏是这样的

并没有卡片的式样，而且生成的骨架屏也不怎么美观。还需要在回调里面慢慢调试

  _tableView.tabAnimated.adjustWithClassBlock = ^(TABComponentManager *manager, __unsafe_unretained Class targetClass) {
              manager.animation(1).down(3).height(12);
              manager.animation(2).height(12).width(110);
              manager.animation(3).down(-5).height(12);
        };

我看了官方的demo，卡片式样是用纯代码写的，试了几次xib 的卡片骨架屏式样始终没有出来，也许是方法不对。但是我也不想把cell重新有纯代码在写一遍。于是就找到了一个新方法。而且生成的骨架屏也符合要求，首先用纯代码把标红色的部分全部用View代替，

初始化骨架屏的时候class 用刚才纯代码写的cell，UITableView还是用之前的xib cell

    self.tableView.tabAnimated = [TABTableAnimated animatedWithCellClass:[TaskTabAnimatedCell class] cellHeight:240];
    self.tableView.tabAnimated.adjustBlock = ^(TABComponentManager * _Nonnull manager) {
    };
