    <p>Newbie here,</p> <p>I have a single component picker set up from a plist, with each item being an array, with multiple strings in each array that the app uses.</p> <p>Currently the plist structure is like this:</p> <pre><code>NSDictionary -&gt; NSArray -&gt; NSString | | Items in Picker Data for each Item </code></pre> <p>But now, I want:</p> <pre><code>NSDictionary -&gt; NSDictionary -&gt; NSArray -&gt; NSString | | | DIfferent Picker Data Sets Items in Picker Data for each Item </code></pre> <p>So now there would be multiple sets of picker components that I would show using a segmented control etc...</p> <p>I'm not even sure if this is possible, and I was only hoping it would save me from making many different separate picker controllers.</p> <p>What has me stumped is just getting everything ingested properly</p> <p>This is what I have now, it builds successfully but crashes (debug info below):</p> <pre><code>NSBundle *bundle = [NSBundle mainBundle]; NSString *plistPath = [bundle pathForResource:@"CamerasDatabase" ofType:@"plist"]; NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:plistPath]; self.allCameras = dictionary; [dictionary release]; NSArray *cameraTypes = [self.allCameras allKeys]; self.CamTypes = cameraTypes; NSArray *items = [self.CamTypes objectAtIndex:0]; self.Cameras = items; NSString *selectedCamera = [self.Cameras objectAtIndex:0]; NSArray *array = [CamsList objectForKey:selectedCam]; self.cameraData = array; </code></pre> <p>I've tried many different combinations of dictionaries, arrays, and strings so I'm sure the above code is messed up.</p> <p>It crashes at:</p> <pre><code>NSString *selectedCamera = [self.Cameras objectAtIndex:0]; </code></pre> <p>with "-[NSCFString objectAtIndex:]: unrecognized selector sent to instance 0x4e127f0"</p>

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.
