Load PDF from documents directory

[Jacos]

Hey, I have a code for viewing, scrolling and zooming. But now the PDF loads from the application bundle. How could I load it from the documents directory?

Here is my code in the ViewDidLoad: method:

- (void)viewDidLoad {
    [super viewDidLoad];
    
	[scrollView removeFromSuperview];
	[myContentView removeFromSuperview];
	[tiledLayer removeFromSuperlayer];
	
	self.view.backgroundColor = [UIColor scrollViewTexturedBackgroundColor];
	self.view.frame = CGRectMake(0, 0, 320, 411);
	
	myDocumentRef = CGPDFDocumentCreateWithURL((CFURLRef)[NSURL URLWithString:@"9A.pdf"]);
	NSURL *pdfURL = [[NSBundle mainBundle] URLForResource:@"9A.pdf" withExtension:nil];
	myDocumentRef = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
	myPageRef = CGPDFDocumentGetPage(myDocumentRef, 1);
	
	tiledLayer = [CATiledLayer layer];
	tiledLayer.delegate = self;
	tiledLayer.tileSize = CGSizeMake(320, 411);
	tiledLayer.levelsOfDetail = 100;
	tiledLayer.levelsOfDetailBias = 100           ;
	tiledLayer.frame = self.view.frame;
	
	myContentView = [[UIView alloc] init];
	myContentView.backgroundColor = [UIColor whiteColor];
	myContentView.frame =  CGRectMake(0, 0, 320, 411);
	
	[myContentView.layer addSublayer:tiledLayer];
	
	CGRect viewFrame =  CGRectMake(0, 0, 320, 411);
	viewFrame.origin = CGPointZero;
	
	scrollView = [[UIScrollView alloc] initWithFrame:self.view.frame];
	scrollView.frame =  CGRectMake(0, 0, 320, 411);
	scrollView.delegate = self;
	scrollView.contentSize = self.view.frame.size;
	scrollView.maximumZoomScale = 5;
	[scrollView addSubview:myContentView];
	
	[self.view addSubview:scrollView];
	
}

All answers is appreciated and thanks in advance!

I would use this to make the URL you pass to CGPDFDocumentWithURL:

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *pdfFilePath = [documentsDirectory stringByAppendingPathComponent:@"name.pdf"];
    NSURL *pdfURL = [NSURL fileURLWithPath:pdfFilePath isDirectory:NO];

Obviously change "name.pdf" to the name of your PDF file in the documents directory. I changed the names to match your naming, so please excuse any small typos.

Thank you so much! It worked perfectly.
