ViewsUIPrintInteractionController printingItems not showing up / working
Pretty straightforward...
I consider myself a fairly well-seasoned iOS developer these days, but this one seems like a glaring bug in iOS, unless I missed something.
Please see the code below.
The file paths point to two one-page PDFs.
What shows up is a Print interaction controller with no content to print.
If I instead only do 1 file at a time like this:
pc.printingItem = [NSURL fileURLWithPath:filePath1];
it works like a champ.
What am I missing here?!
UIPrintInteractionController *pc = [UIPrintInteractionController sharedPrintController];
UIPrintInfo *printInfo = [UIPrintInfo printInfo];
printInfo.outputType = UIPrintInfoOutputPhoto;
printInfo.orientation = UIPrintInfoOrientationLandscape;
pc.printInfo = printInfo;
pc.printingItems = @[[NSURL fileURLWithPath:filePath1],
[NSURL fileURLWithPath:filePath2]];
[pc presentAnimated:YES completionHandler:completionHandler];

I had the same issue and solved it by setting the printingItem property with raw data of my PDF file.
// Here is a class I created that works with `UIActivityViewController`,
// feel free to tweak to your needs.
final class CustomActivityViewController: UIActivityViewController {
init(with filePath: URL, and fileData: Data?) {
super.init(activityItems: [filePath], applicationActivities: [])
completionWithItemsHandler = { activity, complete, items, error in
if activity == .print {
let printInfo = UIPrintInfo(dictionary: nil)
printInfo.jobName = filePath.lastPathComponent
printInfo.outputType = .general
let printer = UIPrintInteractionController.shared
printer.printingItem = fileData // <-- This is the cure.
printer.printInfo = printInfo
printer.present(animated: true, completionHandler: nil)
}
}
}
}
