¿Qué hice mal al principio de "Your Second iOS App" de Apple? [cerrado]

as I am following the second of Apple's beginner-tutorials "Your second iOS App", it seems that I've made a mistake but I can't figure out where:

The tutorial I am referring to: https://developer.apple.com/library/ios/#documentation/iPhone/Conceptual/SecondiOSAppTutorial/GettingStarted/GettingStarted.html

The very first step (the first blue point) is to create a new project. In the next steps this default project gets built & run but the Apple screenshots are different from mine :


While trying to fix the problem I checked the option "Use Core Data" and the app looked like the Apple version. But later on the code of it also doesn't match with the tutorial :(

Thanks for reading & I hope someone can help me with this :)

Edit: maybe it helps to say that a few steps further in the tutorial one has to comment out the following lines of code ("Birds" is the creative prefix of the tutorial so don't wonder :) ):

import "BirdsMasterViewController.h"


@interface BirdsMasterViewController () {

   NSMutableArray *_objects;




@implementation BirdsMasterViewController

In your UITableView's numberOfSections delegate method, is the number 0 or 1? -

"1" and the Content is set to "Static Cells", not to "Dynamic Prototypes" as it should be (?) -

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section? You need to post code. -

I would check if your array is initialized. -

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section]; return [sectionInfo numberOfObjects]; } -
