Cocoa PDF page splitting

Question

In the application I\'m creating, I load a long page of HTML into a webView and then print it to a PDF using the following:

-(void)webView:(WebView *)sender          


        

Answer 1

You get a file with one large page because + PDFOperationWithView: method doesn't support pagination at all. For that reason calling - setVerticalPagination: or - setHoriziontalPagination: doesn't change anything.

You could try use "classical" + printOperationWithView:printInfo: method, configure it to save PDF to temporary location and then create PDFDocument with contents of obtained file. I hope that fragment of code below will help.

NSMutableDictionary *dict = [[NSPrintInfo sharedPrintInfo] dictionary];
[dict setObject:NSPrintSaveJob forKey:NSPrintJobDisposition];
[dict setObject:temporaryFilePath forKey:NSPrintSavePath];
NSPrintInfo *pi = [[NSPrintInfo alloc] initWithDictionary:dict];
[pi setHorizontalPagination:NSAutoPagination];
[pi setVerticalPagination:NSAutoPagination];

NSPrintOperation *op = [NSPrintOperation printOperationWithView:[[[webView mainFrame] frameView] documentView] printInfo:pi];
[pi release];
[op setShowsPrintPanel:NO];
[op setShowsProgressPanel:NO];

if ([op runOperation] ){
    PDFDocument *doc = [[[PDFDocument alloc] initWithURL:[NSURL fileURLWithPath: temporaryFilePath]] autorelease];
    // do with doc what you want, remove file, etc.
}
