    <p>I'm trying to save the name of a button using a singleton so that the name can be accessed in another view to play a video with the same name. However, I'm getting the error: SIGABRT. I don't really see what's wrong with my code. Any ideas? </p> <pre><code>#import "List.h" #import "MyManager.h" #import "Video.h" @implementation ExerciseList -(IBAction) goToVideo:(UIButton *) sender{ MyManager *sharedManager = [MyManager sharedManager]; sharedManager.vidName = [[sender titleLabel] text]; Video *videoGo = [[Video alloc] initWithNibName: @"Video" bundle: nil]; [self.navigationController pushViewController: videoGo animated: YES]; [videoGo release]; } </code></pre> <p>Here is my .h and .m for MyManager:</p> <pre><code>#import &lt;foundation/Foundation.h&gt; @interface MyManager : NSObject { NSMutableArray *workouts; NSString *vidName; } @property (nonatomic, retain) NSMutableArray *workouts; @property (nonatomic, retain) NSString *vidName; + (id)sharedManager; @end #import "MyManager.h" static MyManager *sharedMyManager = nil; @implementation MyManager @synthesize workouts; @synthesize vidName; #pragma mark Singleton Methods + (id)sharedManager { @synchronized(self) { if (sharedMyManager == nil) sharedMyManager = [[self alloc] init]; } return sharedMyManager; } - (id)init { if ((self = [super init])) { workouts = [[NSMutableArray alloc] init]; vidName = [[NSString alloc] init]; } return self; } -(void) dealloc{ self.workouts = nil; self.vidName = nil; [super dealloc]; } @end </code></pre>

    1. COShow the declaration and implementation of the `vidName` property in `MyManager`, and the code that tries to access it. Right now you've shown that you're setting that property, but nothing about how the property is implemented, or what you do after you read from the property.

    3. COThat looks OK. You're not showing where you read from the property, though. Also: Where exactly is it crashing?

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.
