    <p>There are two ways for achieving it. 1.Make a singleton class for shared data(in your case that string which you want to pass from one ViewController to another).</p> <p>2.Declare shared data in appDelegate class.(you should use second mathod because you just want string to be shared).</p> <p>In your appDelegate.h declare your string</p> <pre><code>@property(retain,nonatomic) NSString *YourString; </code></pre> <p>now in your second viewController assign the value you want.</p> <pre><code>AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; appdelegate.YourString = @"Your VAlue"; </code></pre> <p>Now access the same string from first ViewController.</p> <pre><code> AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; self.yourLable.text = appdelegate.YourString; </code></pre> <p><strong>I couldn't attache source code here.it is very simple you just folow the instructions.</strong></p> <p>1.Open AppDElegate.h file and paste following code.</p> <pre><code>@property(strong,nonatomic) NSString *SharedString; </code></pre> <p>2.Now Open SecondViewController.m and import appDelegate.h</p> <pre><code>#import "AppDelegate.h" </code></pre> <p>3.In SeconViewController.m initialize sharedString with your value</p> <pre><code>ViewDidLoad { AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; appdelegate.SharedString=@"Any String"; } </code></pre> <ol> <li><p>Open FirstViewController.m and import appDelegate.h</p> <p>#import "AppDelegate.h"</p></li> </ol> <p>5.In FirstViewController.m paste Following Code</p> <pre><code>- (void)viewDidAppear:(BOOL)animated { AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; self.YouLable.text = appdelegate.SharedString; [super viewDidAppear:NO]; } </code></pre>

    1. COI have a question, where would i add the second line of code which is : AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; appdelegate.YourString = @"Your VAlue"; so where would i place this ? Like in the secondViewController but do i place it in viewDidLoD or in the save button body ?

    2. COIn second viewController you set your string to shared string object i.e. YourString in SecongViewController.m(either in viewDidLoad or IBAction or where ever you want) AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; appdelegate.YourString = @"Your VAlue"; In first viewController's ViewDidLoad assign the same string to your lable or where ever you want. AppDelegate *appdelegate = [[UIApplication sharedApplication] delegate]; self.yourLable.text = appdelegate.YourString;

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
