    <p>I am trying to store a REST connection model in a single object so that I don't keep having to use it over and over again. Here is the model I created:</p> <pre class="lang-c prettyprint-override"><code>//RestModel.h #import "ASIHTTPRequest.h" @interface RestModel : NSObject{ NSString* _baseUrl; NSString* _modelUrl; } @property (nonatomic, retain) NSString* modelUrl; - (id)initWithModel:(NSString*)model; - (NSDictionary*)getById:(NSInteger*)ident; - (NSDictionary*)getAll; @end //RestModel.m #import "RestModel.h" @implementation RestModel @synthesize modelUrl = _modelUrl; - (id)init { self = [super init]; if (self) { _baseUrl = @"http://myRESTurl.com"; } return self; } - (id)initWithModel:(NSString*)model { self = [super init]; if (self) { _baseUrl = @"http://myRESTurl.com"; self.modelUrl = [NSString stringWithFormat:@"%@/%@/", _baseUrl, model]; } return self; } - (NSDictionary*)HTTPRequest:(NSURL*)url { ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; [request startSynchronous]; NSError *error = [request error]; if(!error){ NSData *responseData = [request responseData]; NSString *errorDesc = nil; NSPropertyListFormat format; [error release]; [request release]; return (NSDictionary*)[NSPropertyListSerialization propertyListFromData:responseData mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&amp;format errorDescription:&amp;errorDesc]; }else{ NSLog(@"%@", error); return nil; } } - (NSDictionary*)getById:(NSInteger*)ident { NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"%@/%@", self.modelUrl, ident]]; return [self HTTPRequest:url]; } - (NSDictionary*)getAll { NSURL* url = [NSURL URLWithString:[NSString stringWithFormat:@"%@", self.modelUrl]]; return [self HTTPRequest:url]; } - (void)dealloc { [_modelUrl release]; // [_responseData release]; // [_responseDict release]; [super dealloc]; } @end </code></pre> <p>Edit: Now it isn't crashing, but my local NSDictionary has a count of 0. I'm calling the following in -viewDidLoad in my controller:</p> <pre class="lang-c prettyprint-override"><code>RestModel* rm = [[RestModel alloc] initWithModel:@"user"]; self.dict = [rm getAll]; [rm release]; </code></pre> <p>I planted NSLog of [self.dict count] throughout the controller. It is always 0. The RestModel rm is called, the functions are called (again more NSLogs), but no data. Any ideas?</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.
