Question

I am working on the Popover controller where I create a popover control on the click of a button and then navigate to the class where it displays a table view in a popover class.

Here I want to dismiss the pop over when I tap a table view row.

Here is my code:

//popoverclass.h
UIPopoverController *popover; 
@property(nonatomic,retain)IBOutlet UIPopoverController *popover;

//popoverclass.m
-(IBAction)ClickNext
{
    ClassPopDismiss *classCourse = [[ClassPopDismiss alloc] init];
    popover = [[UIPopoverController alloc] initWithContentViewController:classCourse];
    popover.delegate = self;
    [popover presentPopoverFromRect:CGRectMake(50,-40, 200, 300) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft animated:YES];
    [classCourse release];

}

//ClassPopDismiss.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    PopOverClass *objclass=[[PopOverClass alloc]init];
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
  [objclass.popover dismissPopoverAnimated:YES];

}

The above code is not working.

Answer 1

It’s not possible to dismiss popover from the same class, because the popover is presented from the class popoverclass.m and your table is in ClassPopDismiss.m .

So the best option is to have a custom delegate method in your ClassPopDismiss.h:

// ClassPopDismiss.h
@protocol DismissDelegate <NSObject>

-(void)didTap;

@end

And set an id <DismissDelegate> delegate; in your @interface section.

Call didTap to tell PopOverClass that tableView is tapped.

// ClassPopDismiss.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath  {
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
    [delegate didTap];
}

In your popoverclass.h:

@interface PopOverClass : UIViewController <DismissDelegate>

In your popoverclass.m, don’t forget to assign delegate to self. Like:

ClassPopDismiss *classpop = [[ClassPopDismiss alloc]init];
classpop.delegate=self;

And while using the protocol method:

-(void)didTap
{
    //Dismiss your popover here;
    [popover dismissPopoverAnimated:YES];
}
