The
Completion Shortcut
field in the edit window shows you what to type in a source file
to have
Xcode
add the snippet. This window also tells you that this snippet can be used in

You can't edit any of the pre-defined code snippets, but you can create your own. In
ItemsViewController.m
, locate the implementation of
tableView:numberOfRowsInSection:
. Highlight the entire method:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [[[BNRItemStore sharedStore] allItems] count];
}

that you could fill in easily. In the edit window, modify the code snippet so it looks like
this:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
