Body
copied!<p>I have an application with several tables separated exactly like seen in the Settings on the iPhone. I would like to add a value to be displayed in this label exactly like seen for example in the Settings Wi-Fi or Bluetooth where on the right you have your item and on the left a value is displayed. How can I do this?</p> <p>Setting.h</p> <pre><code>@interface Setting : NSObject { NSString *_settingsID; NSString *_catalogID; NSString *_category; NSString *_facings; NSString *_quantity; } @property (nonatomic, retain) NSString *settingsID; @property (nonatomic, retain) NSString *catalogID; @property (nonatomic, retain) NSString *category; @property (nonatomic, retain) NSString *facings; @property (nonatomic, retain) NSString *quanity; - (Setting *)initWithName:(NSString *)settingsID desc:(NSString *)category CategoryID:(NSString *)catalogID Facings:(NSString *)facings Quantity:(NSString *)quantity; @end </code></pre> <p>Setting.m</p> <pre><code>@implementation Setting @synthesize settingsID = _settingsID; @synthesize catalogID = _catalogID; @synthesize category = _category; @synthesize facings = _facings; @synthesize quanity = _quantity; - (Setting *)initWithName:(NSString *)settingsID desc:(NSString *)category CategoryID:(NSString *)catalogID Facings:(NSString *)facings Quantity:(NSString *)quantity { if ((self = [super init])) { self.settingsID = settingsID; self.catalogID = catalogID; self.category = category; self.facings = facings; self.quanity = quantity; } return self; } @end </code></pre> <p>Next in my connectionDidFinishLoading I have taken the result from the JSON call to my WebAPI and I populate this Setting object....</p> <pre><code>-(void) connectionDidFinishLoading:(NSURLConnection *)connection { self.settings = [NSMutableArray array]; NSError *error = nil; id result = [NSJSONSerialization JSONObjectWithData:receivedData options:kNilOptions error:&error]; if ([result isKindOfClass:[NSArray class]]) { for (NSDictionary *item in result) { NSString *settingsID = [item objectForKey:@"ID"]; NSString *category = [item objectForKey:@"Category"]; NSString *categoryID = [item objectForKey:@"CatalogID"]; NSString *facings = [item objectForKey:@"Facings"]; NSString *quantity = [item objectForKey:@"Quantity"]; Setting *setting = [[Setting alloc] initWithName:settingsID desc:category CategoryID:categoryID Facings:facings Quantity:quantity]; [self.settings addObject:setting]; } } for (Setting *item in self.settings) { NSString *frozen = @"Frozen"; BOOL res = [frozen isEqualToString:item.category]; if (res == TRUE) { **NSLog(@"Original Value: %@, Bool Value: %@", item.facings, item.facings.boolValue == false ?

An individual column

Larger individual text columns get their own page to allow for proper reading.
