    <p>I have the following class called ZipCode and a loadData method that successfully gets data from a third party service and populates my local instantiated ZipCode class. The problem I am having is getting the populated values in this class into 5 local variables I can then pass on to my stored procedure which pulls back from the database the stores surrounding the entered zip code. </p> <p>ZipCode.h</p> <pre><code>@interface ZipCodes : NSObject @property (strong,nonatomic) NSString *city; //adminName2 @property (strong,nonatomic) NSString *stateAbbreviation; //adminCode1 @property (strong,nonatomic) NSString *postalCode; // postalCode @property (strong,nonatomic) NSString *distance; //distance @property (strong,nonatomic) NSString *country; // countryCode @property (strong,nonatomic) NSString *stateName; //adminName1 -(id)initWithName:(NSString *)city stateAbbrev:(NSString *)stateAbbreviation postalCode:(NSString *)postalCode distanceFromGPSZip:(NSString *)distance country:(NSString *)country stateFullName:(NSString *)stateName; @end </code></pre> <p>ZipCode.m</p> <pre><code>@implementation ZipCodes -(id)initWithName:(NSString *)city stateAbbrev:(NSString *)stateAbbreviation postalCode:(NSString *)postalCode distanceFromGPSZip:(NSString *)distance country:(NSString *)country stateFullName:(NSString *)stateName { if (self = [super init]) { _city = city; _stateAbbreviation = stateAbbreviation; _postalCode = postalCode; _distance = distance; _country = country; _stateName = stateName; } return self; } -(NSString *)description { return [NSString stringWithFormat:@"City=%@, State=%@ Zip=%@ is %@ from the original zipCode queried", self.city, self.stateAbbreviation, self.postalCode, self.distance]; } -(NSString *)postalCode { return self.postalCode; // This is where I get a rather long loop... } @end </code></pre> <p>-(void) loadData:(NSString *)zipCode {</p> <pre><code>NSLog(@"GetSurroundingZipCodes is in loadData..."); self.zipCodes = [NSMutableArray array]; NSURL *url = nil; NSLog(@"Get surrounding zip codes url is: %@", url); NSString *zipCode = @"92675"; url = [NSURL URLWithString:[NSString stringWithFormat:@"http://api.geonames.org/findNearbyPostalCodesJSON?postalcode=%@&amp;country=US&amp;radius=10&amp;username=frequentz", zipCode]]; NSURLRequest * urlRequest = [NSURLRequest requestWithURL:url]; NSError *error = nil; NSURLResponse * response = nil; NSData *data = [NSURLConnection sendSynchronousRequest:urlRequest returningResponse:&amp;response error:&amp;error]; self.zipCodes = [NSMutableArray array]; id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&amp;error]; if (jsonObject != nil &amp;&amp; error == nil) { NSLog(@"Successfully deserialized..."); if ([jsonObject isKindOfClass:[NSDictionary class]]) { NSDictionary *deserializedDictionary = (NSDictionary *)jsonObject; NSLog(@"Deserialized JSON Dictionary = %@", deserializedDictionary); for (NSString* key in deserializedDictionary) { id value = [deserializedDictionary objectForKey:key]; for (NSDictionary *item in value) { NSString *city = [item objectForKey:@"adminName2"]; NSString *stateAbbreviation = [item objectForKey:@"adminCode1"]; NSString *postalCode = [item objectForKey:@"postalCode"]; NSString *distance = [item objectForKey:@"distance"]; NSString *country = [item objectForKey:@"country"]; NSString *stateName = [item objectForKey:@"stateName"]; ZipCodes *zipCode = [[ZipCodes alloc] initWithName:city stateAbbrev:stateAbbreviation postalCode:postalCode distanceFromGPSZip:distance country:country stateFullName:stateName]; [self.zipCodes addObject:zipCode]; } } } } else if (error != nil){ NSLog(@"An error happened while deserializing the JSON data."); } // Assign zip codes to first five _zipCode1..5 variables for (int i = 1; i &lt;= 5; i++) { if (i == 1) { // If I comment out the return of zipCode in the ZipCode.m file above the loop goes away and I get a string description that looks like this: self.zipCodes: City=San Francisco, State=CA Zip=94123 is 1.59213 from the original zipCode queried at index: 1 NSLog(@"self.zipCodes: %@ at index: %i", self.zipCodes[i], i); // Here I get the following error: -[ZipCodes objectForKey:]: unrecognized selector sent to instance _zipCode1 = [[self.zipCodes objectAtIndex:i] objectForKey:@"postalCode"]; } else if (i == 2) { _zipCode2 = [[self.zipCodes objectAtIndex:i] objectForKey:@"Zip"]; } //etc...// } } </code></pre>

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.
