UITableViewController with UIPageViewController in UIViewController - ios

Question

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
- (void)viewDidLoad
{
[super viewDidLoad];
self.modelArray = [[NSMutableArray alloc] init];
AppDelegate *app = [[UIApplication sharedApplication] delegate];
self.pdfName = app.strpdfname;
NSString *path = [[NSBundle mainBundle] pathForResource:pdfName ofType:nil];
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]];
}
self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
self.pageViewController.delegate = self;
self.pageViewController.dataSource = self;
contentViewController = [[ContentViewController alloc] initWithNibName:#"ContentViewController" bundle:nil];
contentViewController.labelContents = [self.modelArray objectAtIndex:0];
NSArray *viewControllers = [NSArray arrayWithObject:contentViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward
animated:NO
completion:nil];
[self addChildViewController:self.pageViewController];
[self.view addSubview:self.pageViewController.view];
[self.pageViewController didMoveToParentViewController:self];
CGRect pageViewRect = self.view.frame;
pageViewRect = CGRectInset(pageViewRect, 0.0, 0.0);
self.pageViewController.view.frame = pageViewRect;
self.view.gestureRecognizers = self.pageViewController.gestureRecognizers;
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController
viewControllerBeforeViewController:(UIViewController *)viewController
{
NSUInteger currentIndex = [self.modelArray indexOfObject:[(ContentViewController *)viewController labelContents]];
if(currentIndex == 0)
{
return nil;
}
contentViewController = [[ContentViewController alloc] init];
contentViewController.labelContents = [self.modelArray objectAtIndex:currentIndex - 1];
return contentViewController;
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController
viewControllerAfterViewController:(UIViewController *)viewController
{
NSUInteger currentIndex = [self.modelArray indexOfObject:[(ContentViewController *)viewController labelContents]];
if(currentIndex == self.modelArray.count-1)
{
return nil;
}
contentViewController = [[ContentViewController alloc] init];
contentViewController.labelContents = [self.modelArray objectAtIndex:currentIndex + 1];
return contentViewController;
}
- (UIPageViewControllerSpineLocation)pageViewController:(UIPageViewController *)pageViewController
spineLocationForInterfaceOrientation:(UIInterfaceOrientation)orientation
{
UIViewController *currentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
NSArray *viewControllers = [NSArray arrayWithObject:currentViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:NULL];
self.pageViewController.doubleSided = NO;
return UIPageViewControllerSpineLocationMin;
}
In ContentViewController of PageViewController
-(UIImage*) imageFromPDF:(CGPDFDocumentRef)pdf withPageNumber:(NSUInteger)pageNumber withScale:(CGFloat)scale
{
CGPDFPageRef pdfPage = CGPDFDocumentGetPage(pdf,pageNumber);
CGRect tmpRect = CGPDFPageGetBoxRect(pdfPage,kCGPDFMediaBox);
CGRect rect = CGRectMake(tmpRect.origin.x,tmpRect.origin.y,tmpRect.size.width*scale,tmpRect.size.height*scale);
UIGraphicsBeginImageContext(rect.size);
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextTranslateCTM(context,-50,rect.size.height-30);
CGContextScaleCTM(context,scale,-scale);
CGContextDrawPDFPage(context,pdfPage);
UIImage* pdfImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return pdfImage;
}
- (void)viewDidLoad
{
[super viewDidLoad];
AppDelegate *app = [[UIApplication sharedApplication] delegate];
self.pdfName = app.strpdfname;
i = [labelContents intValue];
NSString *path = [[NSBundle mainBundle] pathForResource:pdfName ofType:nil];
if (i!=0)
{
CGPDFDocumentRef pdf = CGPDFDocumentCreateWithURL((__bridge CFURLRef)[NSURL fileURLWithPath:path]);
UIImage *img = [[UIImage alloc] init];
img = [self imageFromPDF:pdf withPageNumber:i withScale:1];
UIImageView *imgview1 = [[UIImageView alloc] initWithImage:img];
[self.view addSubview:imgview1];
}
else
{
UIImage *imgmain = [UIImage imageNamed:#"Diary4.png"];
UIImageView *imgvmain = [[UIImageView alloc] initWithImage:imgmain];
imgvmain.frame = CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y,580,self.view.frame.size.height);
[self.view addSubview:imgvmain];
}
}
In MainViewController
-(void)viewDidload
{
leftView = [[UIView alloc] initWithFrame:CGRectMake(5,25, 200,715)];
leftView.backgroundColor = [UIColor clearColor];
tvc = [[TableViewController alloc] initWithStyle:UITableViewStylePlain];
tvc.plays = self.plays;
tvc.view.frame = leftView.frame;
leftView.clipsToBounds = YES;
[leftView addSubview:tvc.view];
[self.view addSubview:leftView];
middleView = [[UIView alloc] initWithFrame:CGRectMake(107, 30, 575, 670)];
mvc = [[MiddleViewController alloc] initWithNibName:#"MiddleViewController" bundle:nil];
[mvc.view setFrame:middleView.frame];
[middleView addSubview:mvc.view];
[self.view addSubview:middleView];
}

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.
