    <p>I have made a custom delegate:</p> <p>Example.h:</p> <pre><code>@protocol DismissExamplePopoverDelegate - (void) dismissExamplePopover; - (int) getUserID; @end @interface Example : UIViewController{ id&lt;DismissExamplePopoverDelegate&gt; delegate; } @property (nonatomic, assign) id&lt;DismissExamplePopoverDelegate&gt; delegate; </code></pre> <p>It is called in Example.m like follows:</p> <pre><code>[[self delegate] getUserID]; </code></pre> <p>In my maincontroller.h:</p> <pre><code>#import "Example.h" @interface MainScreen : UIViewController&lt;DismissExamplePopoverDelegate&gt; </code></pre> <p>maincontroller.m:</p> <pre><code>-(int) getUserID { return 100; } </code></pre> <p>the view Example is called by the following method:</p> <pre><code>ExampleController = [[Example alloc] initWithNibName:@"Example" bundle:nil]; ExamplePopoverController = [[UIPopoverController alloc] initWithContentViewController:ExampleController]; [ExampleController setDelegate:self]; ExamplePopoverController.popoverContentSize = CGSizeMake(600, 480); if ([ExamplePopoverController isPopoverVisible]) { [ExamplePopoverController dismissPopoverAnimated:YES]; } else { CGRect popRect = CGRectMake((self.EditExampleSelectAddButtonProperty.frame.origin.x), (self.EditExampleSelectAddButtonProperty.frame.origin.y), (self.ExampleSelectAddButtonProperty.frame.size.width), (self.ExampleSelectAddButtonProperty.frame.size.height)); [ExamplePopoverController presentPopoverFromRect:popRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } </code></pre> <p>If I place <code>[[self delegate] getUserID]</code> in any function other than <code>viewdidload</code> it works perfectly: returns 100; in <code>viewdidload</code> it returns 0.</p> <p>What i want to achieve is a delegate to be called automatically when the popover loads. Is viewdidload the best place for it, or is there somewhere else</p>

    3. CONo. You create an `Example` object - say `myExample`. Show this code and the code where you do `myExample.delegate = self;` (or whatever you assign to the delegate property).

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.

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