/*************<isTranslucent默认是true>********************
特殊说明：导航栏isTranslucent的true与false会影响tableview底部是否下沉64-->true不会下沉64
1,（代码实现）
self.navigationController?.navigationBar.isTranslucent = true---> tableview不会下沉64
self.navigationController?.navigationBar.isTranslucent = false---> tableview会下沉64
2, (xib实现)
isTranslucent = false, tableview、scrollview则top应设置为-->0;
isTranslucent = true, tableview、scrollview则top应设置为-->64;
3, 此处使用-->
<1>isTranslucent = true
let H: CGFloat = is_iphoneXBS ? (UIScreen.main.bounds.height - Y - 34 - 0) : (UIScreen.main.bounds.height - Y - 0)
<2>isTranslucent = false
let H: CGFloat = is_iphoneXBS ? (UIScreen.main.bounds.height - Y - 34 - 64) : (UIScreen.main.bounds.height - Y - 64)
