This method is called when sliding TableView. We need to determine the sliding distance of TableView in this method.

Create a new SliderBar file. The content of the SliderBar. h file is as follows:

The content of the SliderBar. cpp file is as follows:

After that, SliderBar still needs to be used in combination with TableView. First, create the tableView and sliderBar objects in the HelloWorld initialization method (do not forget the implementation of the tableView Protocol and related methods, which is omitted here ).

The following code is added to the tableView rolling callback method:

In this way, you can see the above effect.
