Memory Management of Core Data NSFetchedResultsController with a UITableView
I would like to use a NSFetchedResultsController to provide me the contents of a simple UITableView with the following properties:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
The two last methods do not implement any actions. They just return a value so that I can know the index of the row I have just selected.
I have been following a guide and I implemented the method tableView:cellForRowAtIndexPath:. I got really confused with the memory management. As you can see in the following example, the code creates a dictionary of objects called personDict and it also takes an array of objects called names and stores them in the same dictionary (personDict).
//NSFetchedResultsController

NSFetchRequest *request = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Person" inManagedObjectContext:moc]; ac619d1d87
