I have a screen with two views :

  • An UITableView (tableView) on the right hand side, that takes half of the screen
  • An UIView (controllerView) on the left hand side that takes the other half of the screen

Here’s an example

Tranfer Scroll to TableView

I’d like the left view to “control” the UITableView : when the user scrolls from top to bottom, it should scroll the UITableView from top to bottom, as if the user would have made the same gesture but with a right offset.

I’ve found a similar question, but no answer.

    Add touches handling methods to your Control View (controllerView)

    - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event;
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event;

    Calculate change of Y coordinate of touch and scroll tableView with

    - (void)scrollRectToVisible:(CGRect)rect animated:(BOOL)animated

    method.
