I am just starting developing an application where there is a graphical
representation of a tree structure for the user to manipulate. Each node of
the tree has things like an editable text field, some buttons and images
etc. I want to allow the users to be able to drag the nodes around into
different positions and redraw the graph as required.

For the background I will use a scrollview, but I am not sure whether things
will be easier for me to add subviews to my clipview so that each node is a
subview, and then perhaps use the standard dragging protocols from there, or
whether I should do something like the Sketch example and just have a single
view that looks after drawing the different bits by having an array of
graphic objects that draw themselves (and handle manipulation through
mousedown and next event matching mask etc).

Any recommendations of the best structure to use would be great...

TIA
