Hi,
I am using a UITableViewController and the data for the table view is
generated dynamically (fetched from the network). The data is normally
fetched based on some search. But when the Controller is loaded and i don't
have the data ready, i want to return something back sane and later reload
the data when it becomes ready. What is the best way to do this ?
-numberOfSectionsinRow : Is it safe to assume that this function is called
always *first* before constructing the table ? At least i want to be able to
initiate the fetch (if it is not already done before) here.
-As i can't return 0 for numberOfSectionsInRow, i still have to return 1
there and in numberOfRowsInSection, return zero till the data becomes
available
The problem is that i need to initiate the fetch somewhere during the table
construction and i don't want to put hooks into all of the tableView
delegate methods. As the data for the tableview is dynamic, i need to tell
the framework not to call the other delegate methods till i return something
valid in numberOfSectionsInRow/numberOfRowsInSection. Is this a safe
assumption ?
thanks
mohan
