close ios done button

I want to close pdf when I clicked "done" button.
- (void)dismissReaderViewController:(RDPDFViewController *)viewController
{
[self dismissViewControllerAnimated:YES completion:NULL];
}

-(void)openPDF:(NSString *)bookId fileName:(NSString *)fileName title:(NSString *)title{
[self loadSettingsWithDefaults];


int result = [m_pdf PDFOpen:pdfFullPath:@"password"];
if(result == 1)
{




int pageno =1;
[m_pdf PDFThumbNailinit:pageno];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(dismissReaderViewController)];
doneButton.title = @"Done";
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:m_pdf];


[navController.navigationBar setBarStyle:UIBarStyleDefault];
m_pdf.navigationItem.leftBarButtonItem=doneButton;

[self presentViewController:navController animated:YES completion:NULL];
}

Hi,

I tried to do the same steps to show show the reader with presentViewController method.
The only thing that you should fix, is the doneButton declaration: @selector(dismissReaderViewController:) instead of @selector(dismissReaderViewController).
The ":" allow to call your method (dismissReaderViewController) correctly.

When vClose method is called, the pdf will be saved if necessary. The vClose method is called in RDPDFViewController, viewWillDisappear method.
If I correctly understood, in your project you can open a pdf file, but you can't close it with your button, right?

Another thing that you should fix is - (void)dismissReaderViewController:(RDPDFViewController *)viewController definition.
if you call that method with the "done" button, it will pass itself as parameter, not RDPDFViewController; so, your method should be:
- (void)dismissReaderViewController
{
....
}
the RDPDFViewController instance is unused in your implementation.
in this way you can restore the previous declaration of the done button (@selector(dismissReaderViewController)) without ":".

Another question: openPDF and dismissReaderViewController methods, are implemented in the same class? If not, you should do it (it could be the most important reason).

Hope it could help
