let page = document?.page(at: 0)

let pdfView = CPDFView(frame: self.view.bounds)
    
// Set the document to be displayed.
pdfView?.document = document
pdfView?.beginEditingLoadType([.text, .image, .path])

objective-c

NSURL *url = [NSURL fileURLWithPath:pdfPath];
CPDFDocument *document = [[CPDFDocument alloc] initWithURL:url];

CPDFView *pdfView = [[CPDFView alloc] initWithFrame:self.view.bounds];

// Set the document to be displayed.
pdfView.document = document;
[pdfView beginEditingLoadType:CEditingLoadTypeText | CEditingLoadTypeImage | CEditingLoadTypePath];
