UITableViewController with UIPageViewController in UIViewController

1k views Asked by At

What I m Thinking to do is ? there is one MainViewController in which there are two UIViews one loaded UITableViewController and other UIPageViewController. In TableViewController, there are list of pdf's names. But when i click of the pdf list, it does not loads the PageViewController with new pdf in context.

Pdf file names are store in .plist file, Pdfs are fetch from NSBundle or NSDocumentDirectory

In TableViewController

-(void)tableView:(UITableView*)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath 
    {
        [tableView deselectRowAtIndexPath:indexPath animated:YES];    
        Play *play = (Play *)[[self.sectionInfoArray objectAtIndex:indexPath.section] play];
        Quotation *qute = [play.Details objectAtIndex:indexPath.row];
        if ([qute.Key isEqualToString:@"ABC"])
        {
            AppDelegate *app = [[UIApplication sharedApplication]delegate];
            app.strpdfname = qute.Value;
            MiddleViewController *mid = [[MiddleViewController alloc] initWithNibName:@"MiddleViewController" bundle:nil];
            ContentViewController *cvc = [[ContentViewController alloc] initWithNibName:@"ContentViewController" bundle:nil];
            [mid viewDidLoad];
            [cvc viewDidLoad];
        }
        else
        {
            MainViewController *vc = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil];
            [vc viewDidLoad];
        }
    }

In PageViewController

        NSURL *targetURL = [NSURL fileURLWithPath:path];

        originalPDF = CGPDFDocumentCreateWithURL((__bridge CFURLRef)targetURL);
        numberOfPages = CGPDFDocumentGetNumberOfPages(originalPDF);

        for (int index = 0; index < numberOfPages ; index++)
        {
            [self.modelArray addObject:[NSString stringWithFormat:@"%d",index]];
        }

As there is no reload data method for UIPageViewController. I was using UIPageViewController in UIViewController instead of that I use UINavigationController in which the UIPageViewController can be reloaded with dynamic data.So on click of UITableViewController, data is sends to UINavigationController-->UIPageViewController. This has solved the above issue.
