i just tried the following with Xcode3:
1)
read a plist in awakeFromNib
store its content in an array
NSArray* myArray = [NSPropertyListSerialization ........
2)
tried to setup my tableview like so:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myArray count]; }

3) but in 2) i get an error telling me, that myArray is undeclared (it was declared in awakeFromNib) What did i forget?

If a variable is declared in a method, then the variable is local to that method. Turn it into an instance variable.

I would suggest reading this:

Another thing: I tried to drag the header file of the above to the interfacebuilder windows which includes the tableview, but no unlike in interfacebuilder2 nothing happens (no "datasource box"). Whats wrong here?

In IB3, there is no need to drag the file into IB. If an outlet or action isn't showing up in IB3, it is because you haven't declared it correctly.

As for dragging connections, it is still ctrl-drag from source (possibly an outlet) to destination (possibly an action). For dataSource, you drag from the table view to the object that is intended to be the data source.
