    return cell;

here is the .h file:

@interface familySelect : UIViewController 
    <UITableViewDelegate, UITableViewDataSource> {
    NSArray *colorNames;
}

@property (nonatomic, retain) NSArray *colorNames;

@end

and in the .xib file i've set the table view dataSource and delegato to the File's Owner (familySelect)

don't understand where is the problem, thanks开发者_JAVA技巧 for any help

You will need to make the following connections within Interface Builder

• table to File's Owner (select delegate)
• table to File's Owner (select datasource)
• File's Owner to view (select view) : this connection is made automatically
• File's Owner to table (select tableView)

Where is your IBOutlet UITableView* myTableView ?

It seems you have passed the Tableview's method on the View Controller and hence crashing.

 -[UIViewController tableView:numberOfRowsInSection:]

You have connected the View for the VIew Controller to the TableView. Instead, declare a UITableView and connect this tableview over there.
