    <p>Is there something important I need in RoomItem to ensure that this method isn't skipped? It's the very first one in my detail view controller, and it is continually skipped when I'm in debugging mode. I'm sure I'm missing something ridiculously simple, but I've been staring at it for hours and just can't figure out what it is.</p> <pre><code>@interface DetailViewController () - (void)configureView; @end @implementation DetailViewController - (void)setDetailItem:(RoomItem *)newDetailItem { if (_detailItem != newDetailItem) { _detailItem = newDetailItem; // Update the view. [self configureView]; } } - (void)configureView { // Update the user interface for the detail item. if (self.detailItem) { [_roomTxt setText:[_detailItem room]]; [_buildingTxt setText:[_detailItem building]]; [_dateTxt setText:[self dateCreatedString]]; [_buildingImageView setImage:[_detailItem buildingImage]]; _oi = [_detailItem objectIndex]; } } </code></pre> <p><strong>MasterViewController (root table view) methods that alloc and init new and existing detailViewControllers</strong></p> <pre><code>- (void)insertNewObject:(id)sender { //add button invokes this DetailViewController *ivc = [[DetailViewController alloc] init]; [self.navigationController pushViewController:ivc animated:YES]; NSLog(@"detailViewController allocated and initialized: %@", ivc); } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (!self.detailViewController) { self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; NSLog(@"detailViewController initialized: %@", self.detailViewController); } //navigates to detailViewController and passes it the item's data self.detailViewController.detailItem = [[[RoomList sharedStore] getAllItems] objectAtIndex:[indexPath row]]; [self.navigationController pushViewController:self.detailViewController animated:YES]; } </code></pre> <p><strong>Here is the tableView:didSelectRowAtIndexPath method that should be passing everything needed by the detail view controller, from the RoomList:sharedStore:</strong></p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (!self.detailViewController) { self.detailViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil]; } //navigates to detailViewController and passes it the item's data self.detailViewController.detailItem = [[[RoomList sharedStore] getAllItems] objectAtIndex:[indexPath row]]; [self.navigationController pushViewController:self.detailViewController animated:YES]; } </code></pre> <p><strong>...and the RoomItem.m file:</strong></p> <pre><code>- (void)awakeFromFetch { [super awakeFromFetch]; UIImage *pic = [UIImage imageWithData:[self buildingThumbnailData]]; [self setPrimitiveValue:pic forKey:@"buildingThumbnail"]; } - (id)initWithRoom:(NSString *)room Building:(NSString *)building { self = [super init]; if (self) { [self setRoom:room]; [self setBuilding:building]; } return self; } </code></pre> <p><strong>DetailViewController.h</strong></p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @class RoomItem; //pic edit: added delegates @interface DetailViewController : UIViewController &lt;UINavigationControllerDelegate, UIImagePickerControllerDelegate, UITextFieldDelegate, UIPopoverControllerDelegate, UIPageViewControllerDelegate&gt; { __weak IBOutlet UITextField *roomField; __weak IBOutlet UITextField *buildingField; __weak IBOutlet UILabel *dateLabel; UIPopoverController *imagePickerPopover; } @property (nonatomic, strong) RoomItem *detailItem; @property (weak, nonatomic) IBOutlet UIButton *updateBtn; @property (weak, nonatomic) IBOutlet UIButton *detailsBtn; @property (weak, nonatomic) IBOutlet UITextField *roomTxt; @property (weak, nonatomic) IBOutlet UITextField *buildingTxt; @property (weak, nonatomic) IBOutlet UILabel *dateTxt; @property (weak, nonatomic) IBOutlet UIImageView *buildingImageView; @property (weak, nonatomic) UIImage *buildingImage; @property (weak, nonatomic) NSNumber *oi; - (IBAction)backgroundTapped:(id)sender; - (IBAction)takePicture:(id)sender; - (IBAction)updateRoomItem:(id)sender; - (IBAction)goToReportDetails:(id)sender; @end </code></pre> <p><strong>Edit:here is a pseudo-UML diagram that illustrates what I'm seeing when I step through with the debugger (it reads from left to right, top to bottom):</strong> <img src="https://i.stack.imgur.com/HmhJr.jpg" alt="enter image description here"></p>

    1. CODid you put a breakpoint *before* the if statement in your setter? I assume the setter is in your detail view controller `.m` file.

    2. COI did use a breakpoint at the if statement in the setter, and it never hit it. It is at the very top of the DetailViewController.m file, but it skips immediately to the -(void)configureView method just below it. I've added that to the initial post.

    3. COI have seen mutters lately about xcode failing to implement breakpoints in some cases, although nothing definite. Have you tried NSLog statements in your setter method? Is that the only code that calls configureView?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
