    <p>I have a function that returns a NSUrl, and i want to use it in another class. But when i tried to retrieve it in my other class, it gives me null. This is my First Class</p> <pre><code>@interface UOEventDetailController : UIViewController { NSURL *imgData; } @property(nonatomic, retain)NSURL *imgData; -(NSURL *)imgData; @implementation UOEventDetailController @synthesize imgData; </code></pre> <p>The .m File</p> <pre><code>-(NSURL *)imgData{ UOEventPost *post = (UOEventPost *)self.event; NSURL *url = [NSURL URLWithString:post.postImageURL]; return url; } </code></pre> <p>I want to retrieve the URL in this class</p> <pre><code>@class UOEventDetailController; @interface UOEnlargeImageViewController : UIViewController { IBOutlet UIImageView *enlargedImage; } @property (nonatomic, retain) UOEventDetailController *controller; @property (nonatomic, retain) IBOutlet UIImageView *enlargedImage; </code></pre> <p>the .m file</p> <pre><code>@implementation UOEnlargeImageViewController @synthesize controller; @synthesize enlargedImage; - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Enlarged Image"; controller = [[UOEventDetailController alloc]init]; NSURL *url = [controller imgData]; NSLog(@"%@",url); } @end </code></pre> <p>I can retrieve objects other than post.postImageUrl. For Example instead of post.postImageUrl, i put in string like @"omg", @"god" it gets retrieved in my other class...</p> <h2>EDIT</h2> <pre><code>-(IBAction)enlargeImg{ UOEventPost *post = (UOEventPost *)self.event; UOEnlargeImageViewController *enlarge = [[UOEnlargeImageViewController alloc]initWithNibName:nil bundle:nil]; enlarge.temp = post.postImageURL; [self.navigationController pushViewController:enlarge animated:YES]; [suggestPopupView removeFromSuperview]; [enlarge release]; } </code></pre>

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.
