    <p>When you push the event view controller, the <code>Back</code> button will appear with the title "Back" by default, so you do not have to change it manually. However, if you decide to change the <code>Back</code> button, you can do so by assigning a new object of type <code>UIBarButtonItem</code> to the <code>backBarButtonItem</code> property of your navigation item. For example, you can modify the <code>pushController:</code> method to give our root view controller a custom <code>Back</code> button before pushing the event view controller. <br> </p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; self.eventStore = [[EKEventStore alloc]init]; NSTimeInterval nsYear = 1 * 365 * 24.0f *60.0f * 60.0f; NSDate *startDate = [[NSDate date] dateByAddingTimeInterval:-nsYear]; NSDate *endDate = [NSDate date]; NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate endDate:endDate calendars:self.eventStore.calendars]; NSArray *events = [self.eventStore eventsMatchingPredicate:predicate]; if ([events count]&gt; 0) { EKEvent *event = [events objectAtIndex:0]; EKEventViewController *controller = [[EKEventViewController alloc]init]; controller.event = event; controller.allowsEditing = YES; controller.allowsCalendarPreview = YES; controller.delegate = self; self.navigationItem.backBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:@"Go BACK OK" style:UIBarButtonItemStylePlain target:nil action:nil]; [self.navigationController pushViewController:controller animated:YES]; } } </code></pre> <p>Hope, this will help.</p>

    1. CODoesn't work. This will only change the root view controller's leftbutton not the back button of EKEventViewController that I am about to push.

    2. COI have tried this & it worked for me. I have downloaded the sample code of "EKEventViewController" from Apple website and added a new back button with an image and it worked.

    3. COI presume it is SimpleEKDemo, I tried what you suggested again and it got me same result. How does changing leftbarbutton of root controller change the backbarbutton of the detail view controller that is about to be pushed?

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.
