    <p>it is my first app that I am trying to do on my own and I have some questions. I want to have 4 tabs, and in the first one named "HomeView" I am parsing JSON data (this is done so far).</p> <p>But what I want is some of the data that are being parsed to be visible in other tabs (and not have to parse them again).</p> <p>So parts of my code of HomeView is here:</p> <pre><code>#import "HomeView.h" @interface HomeView () @end @implementation HomeView //other code - (void)connectionDidFinishLoading:(NSURLConnection *)connection { //data fetched parsed_date=[res objectForKey:@"date"]; NSLog(@"Date:%@",parsed_date); [UIAppDelegate.myArray addObject:parsed_date]; } </code></pre> <p>and I can see the "parsed_date" being printed out correctly.</p> <p>So I want this parsed_date to be visible in OtherView.</p> <p>This is my code but I cannot print it out.</p> <p>OtherView.m</p> <pre><code>#import "OtherView.h" #import "HomeView.h" #import "AppDelegate.h" @interface OtherView () @end @implementation OtherView @synthesize tracks_date; - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. //preview value of other class tracks_date = [UIAppDelegate.myArray objectAtIndex:0]; NSLog(@"Dated previed in OtherView: %@", tracks_date); } </code></pre> <p>and (null) is being printed out.</p> <p>added code of app delegate.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #define UIAppDelegate ((AppDelegate *)[UIApplication sharedApplication].delegate) @interface AppDelegate : UIResponder &lt;UIApplicationDelegate&gt; @property (strong, nonatomic) UIWindow *window; @property (nonatomic, strong) NSArray *myArray; @end </code></pre> <p>So can you suggest me a sollution?</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.
