    <p>I'm Trying to dismiss a popover and transfer data at the same time. I implemented a delegate DismissPopoverDelegate but it is failing to work. But there are no errors. If the save button is tapped it registers it and it completes the line after where it calls the delegate. But its not working...</p> <p>AddEventViewController_iPad.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;AddressBook/AddressBook.h&gt; #import &lt;AddressBookUI/AddressBookUI.h&gt; #import &lt;EventKit/EventKit.h&gt; #import &lt;EventKitUI/EventKitUI.h&gt; #import &lt;MessageUI/MessageUI.h&gt; #import &lt;MessageUI/MFMailComposeViewController.h&gt; #import &lt;Foundation/Foundation.h&gt; #import "AboutSme.h" #import "dateViewPopOverViewController_iPad.h" #import "addPersonViewControllerPopover_iPad.h" #import "PreviousEventsTableViewControllerPopover_iPad.h" @interface AddEventViewController_iPad : UIViewController &lt;UITableViewDelegate, UITableViewDataSource, MFMailComposeViewControllerDelegate, UITextFieldDelegate, UIAlertViewDelegate,UIPopoverControllerDelegate,UINavigationControllerDelegate,UIPopoverControllerDelegate,ABPeoplePickerNavigationControllerDelegate, ABNewPersonViewControllerDelegate, DismissPopoverDelegate&gt; { UIPopoverController *pop; </code></pre> <p>AddEventViewController_iPad.m</p> <pre><code> - (IBAction) selectStartDate:(id) sender { NSLog(@"Select start date"); dateViewPopOverViewController_iPad *dateViewPopOverViewController = [[dateViewPopOverViewController_iPad alloc] init]; popover2 = [[UIPopoverController alloc] initWithContentViewController:dateViewPopOverViewController]; popover2.delegate = self; popover2.popoverContentSize = CGSizeMake(320, 460); CGRect rect = CGRectMake(790, 170, 175, 300); [popover2 presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES]; [dateViewPopOverViewController release]; /* if (dateViewController == nil) { dateViewController = [[DateViewController_iPad alloc] initWithNibName:@"DateViewController_iPad" bundle:nil]; } [self presentModalViewController:dateViewController animated:YES]; [dateViewController retain]; */ } - (void) dismissWithData:(NSString *)data { NSLog(@"%@", data); [pop dismissPopoverAnimated:YES]; [pop release]; } </code></pre> <p>dateViewPopOverViewController_iPad.h</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; #import &lt;Foundation/Foundation.h&gt; @protocol DismissPopoverDelegate &lt;NSObject&gt; @required - (void) dismissWithData:(NSString *)data; @end @interface dateViewPopOverViewController_iPad : UIViewController { IBOutlet UIDatePicker *datePicker; IBOutlet UISegmentedControl *segmentedBar; IBOutlet UILabel *startLabel; IBOutlet UILabel *endLabel; IBOutlet UISwitch *allDaySwitch; NSDate *startDate; NSDate *endDate; NSDate *now; NSDateFormatter *dateFormatter; id&lt;DismissPopoverDelegate&gt; delegate; } @property (retain) id delegate; - (void) dismissWithData:(NSString *)data; dateViewPopOverViewController_iPad.m @implementation dateViewPopOverViewController_iPad @synthesize startDate, endDate, datePicker, segmentedBar, startLabel, endLabel, now, allDaySwitch, delegate; - (IBAction) save:(id)sender { if ([self startDateIsValid] &amp;&amp; [self endDateIsValid]) { //[[self parentViewController] setDatesForEvent:startDate eventEndDate:endDate allDay:[allDaySwitch isOn]]; // [self dismissModalViewControllerAnimated:YES]; NSLog(@"works"); [self.delegate dismissWithData:@"Some text from popover"]; NSLog(@"works1"); } else { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Ooops!" message:@"Please check the dates!

    3. COAnd just to point it out, you should not retain the delegate. you should have its property as assign to avoid circular references (which will cause a memory leak). check the answers at this post http://stackoverflow.com/questions/5811590/release-a-viewcontroller-correctly-that-sets-it-self-as-delegate-to-other-classes/5813247#5813247

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).
