The holes we met in IOS those years

1 Pit: The first cell of the UITableView moves down

Cause: IOS7 and later versions, if Uiscrollview is the first child of its parent view, the offset is automatically added. UITableView inherit from Uiscrollview, so there is an offset.

Workaround: Add an empty view as the first child view of the parent view. (Place the desired scrollview below the empty view as the second child view)

UIView *view = [[UIView alloc] init];
[Scrollview.superview Addsubview:view];

If you specify the distance between the first cell and the top edge of the UITableView, you can:

Tableview.contentinset = Uiedgeinsetsmake (40, 0, 0, 0);
