Question on some codes (PDF Viewer)

[Zala]

// Create an instance of PDFViewController
	PDF *pdfView = [[PDF alloc] initWithNibName:@"PDF" bundle:nil];
	
	// Get the path to our documents directory
	NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
	
	// This should be our documents directory
	NSString *saveDirectory = [documentPath objectAtIndex:0];
	
	// Our PDF is named 'Example.pdf'
	NSString *saveFileName = @"example.pdf";
	
	// Create the full path using our saveDirectory and saveFileName
	NSString *finalPath = [saveDirectory stringByAppendingPathComponent:saveFileName];
	
	// Set the pdfUrl to our finalPath
	pdfView.pdfUrl = [NSURL fileURLWithPath:finalPath];
	
	// Push 'controller'
	[self.navigationController pushViewController:pdfView animated:YES];
	
	// Release 'controller'
	[pdfView release];

I am trying to understand this part of the code.

As far as i know i do not see where can i set the values of the "documentPath" and "saveDirectory".

example a "finalpath" should be " c:/Users/a/Desktop/example.pdf"

from my little knowledge i should be able to set to the variable "saveDirectory". But i just do not know how.

Anyone can shed some light?

*yes even with the comments i am so weak
