=======================================================

Common Properties of Cell:

1: Set up auxiliary views: Accessorytype and Accessoryview

The difference between accessorytype is American drama type: The value is usually fixed several

Accessoryview receives a UIView control: But here the control has a default frame, like: uiswitch;

However, normal does not have a default frame, and if you do not set frame it will not be displayed

2: Set color: Background color, color when selected:

Background color: Backgroundview and BackgroundColor

Difference: Backgroundview priority is higher than backgroundcolor and will overwrite BackgroundColor's display

Second: Backgroundview can receive a control, BackgroundColor is inherited from UIView, can only receive Uicolor

Color When selected: Selectedbackgroundview
