Answer 1

In your current scenario, I don't think there is any need to change the cell size on tap. You can play with your view's (inside cell) frame.

1. Just create the cell with the same size equal to the selected cell size .
2. Make the background of the cell clear color.
3. In non-selected state, make the view's y around 25 pixels lower and hide that horizontal line .
4. On selection, stretch the view's y to around 20 pixels upper side, show that horizontal line and change the height accordingly.
