    <p>I am having two view controllers 'FirstViewController' and 'SecondViewController'. From first view controller it will take input from a text field ,process it and display accordingly in the second view. But I am having a problem while setting label value directly.</p> <pre><code> @interface SecondViewController : UIViewController { NSString *numPlate; IBOutlet UILabel *output; }; @property(strong,nonatomic) NSString *numPlate; @property(strong,nonatomic) IBOutlet UILabel *output; @end </code></pre> <p>The main file for FirstViewController.m with prepare for segue is as</p> <pre><code>-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { if([[segue identifier] isEqualToString:@"Change"]) { SecondViewController *svc = (SecondViewController *)[segue destinationViewController]; svc.numPlate = input.text; NumberPlate *numPlate=[[NumberPlate alloc]init]; [numPlate setPlate:input.text]; NSInteger flag=[numPlate checkValidity]; if(flag==0) { svc.output.text =@"Invalid License"; } else if([numPlate getArea]==NULL||[numPlate getRegOffice]==NULL) { svc.output.text =@"Data not found"; } else { svc.output.text =@"VALID License"; } } } </code></pre> <p>But when the action is performed its not working.The label is not changing. When i used svc.numPlate instead of svc.output.text and in the SecondViewController viewDidLoad method and i used </p> <pre><code> - (void)viewDidLoad { [super viewDidLoad]; output.text=numPlate; } </code></pre> <p>Everything is fine with this. Whats wrong in first method??</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.

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).
