I have 2 VCs, first is <code>BooksDetailViewController</code> which has the NSString <code>myBookString</code>. Another on is <code>FavBooksViewController</code> which has the <code>favBookList</code> NSMutableArray. I want to pass the NSString <code>myBookString</code> from the 1st VC to include it in the <code>favBookList</code> NSMutableArray which then populates the table. I have included <code>@class FavBooksViewController;</code> in the <code>BooksDetailViewController.h</code> Imported <code>#import "FavBooksViewController.h"</code> in the <code>BooksDetailViewController.m</code> The action in the <code>BooksDetailViewController.m</code> looks like this: <pre><code>- (IBAction)addToFav:(id)sender { FavBooksViewController *mdvc; [mdvc.self.favBookList addObject:myBookString]; } </code></pre> In <code>FavBooksViewController.h</code> I have <pre><code>@interface FavBooksViewController : UIViewController <UITableViewDataSource, UITableViewDelegate> @property (strong, nonatomic) id delegate; @property (nonatomic,strong) NSMutableArray *favBookList; </code></pre> In the <code>FavBooksViewController.m</code> - <code>#import "FavBooksDetailViewController.h"</code> In the ViewDidLoad I tried to include this line <pre><code>self.favBookList = [[NSMutableArray alloc]initWithObjects:nil]; </code></pre> But I have commented it out. With it our without it the UITableView isn't working. And of course I have this: <pre><code>- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [self.favBookList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"favBooksCell"]; cell.textLabel.text = [self.favBookList objectAtIndex:indexPath.row]; return cell; } </code></pre> No matter what, the UITableView is just empty, no cells, nothing. What can be the possible mistake here? What am I doing wrong? Thanks in advance!

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
