So navigieren Sie zu Viewcontrollern von erweiterten/verschachtelten UITableViewCells

Question

Verwenden Alex Di Mangos POPDownMenuTable-Master-Setup erweitert verschachtelte UITableviewCell und erfolgreich funktioniert gut in meinem Projekt ... Aber jetzt ist das Problem, wie zu anderen View-Controller aus dem navigieren Menü und verschachtelte/-erweiterung Untermenü UITableViewCells ... mit didSelectRowAtIndexPth wie alles programmatisch unter Code verweisen created..Please ...

Answer 1

In DidSelectRowAtIndexPath

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    [self.tableView deselectRowAtIndexPath:indexPath animated:YES]; 
    if (indexPath.row ==0) { 
     [self performSegueWithIdentifier:@"SegueIdentifier0" sender:self]; 
    }else if(indexPath.row==1{ 
     [self performSegueWithIdentifier:@"SegueIdentifier1" sender:self]; 
    }//and so on 
} 

je nachdem, wie viele s Egues du hast, könnte das weitergehen. Im Storyboard müssen Sie die Anzahl der Prototypzellen erhöhen, indem Sie bei der Auswahl von tableView zum Attributinspektor gehen. Sie müssen auch control-click-drag auf die ViewControllers, mit denen Sie segmentieren möchten, auswählen und drücken. Dann nennen Sie die Identifier „SegueIdentifer0“ ...

dann brauchen Sie eine prepareForSeque Methode

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 

if ([segue.identifier isEqualToString:@"SegueIdentifier0"]) { 
    NSLog(@"Segue1"); 
    }else if ([segue.identifier isEqualToString:@"SegueIdentifier1"]){ 
     NSLog(@"Segue2"); 
    } 
} 

Answer 2

Sie nicht segues zu verwenden sind verpflichtet, können Sie immer Ihre Viewcontrollers von Code initialisiert werden und dann präsentieren sie:

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    [tableView deselectRowAtIndexPath:indexPath animated:YES]; 
    NSString *identifier = @""; 

    if (indexPath.row ==0) { 
     identifier = @"VC1"; 
    } 
    else if(indexPath.row==1) { 
     identifier = @"VC2"; 
    } 

    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; 
    UIViewController *viewController = [storyboard instantiateViewControllerWithIdentifier:identifier]; 
    [self.navigationController showViewController:viewController sender:NULL]; 
}
