A simple toolkit for filling out PDF forms in iOS.

ilpdfkit's Issues

Import UIKit and CoreGraphics header files

When I dropped ILPDFKit folder in a swift project I was't able to build it. Turns out I need to import UIKit and CoreGraphics for some classes in ILPDFKit.
I can prepare PR if you need that.

Internal navigation is not Working Properly

Hi ,
I have found below issue in latest updated ILPDFKit

While jump to page 10 from page 1 , interactive Elements are not showing.
Ex. while navigating to 10th page it shows the elements of 5th page.

Navigating single page works fine.

Saving partially flattened data

I would like to save the PDF document in such a way that the form elements are flattened, but interactive URLs remain clickable. Can you give any info as to how to modify flattenedData: method to achieve that? I looked over the class reference and can't seem to see anything that relates to clickable links.

Filled values doesn't show on Adobe Reader

Values filled by the library does show in the app, but it doesn't show up in Adobe Reader, they only appear only when you focus on the field. Any idea?

Do we need something extra while saving the filled values ?

Please help.

Thanks.

Saved pdf is corrupt

After editing and saving a form pdf, it doesnt open in acrobat reader. However, it opens in the browser.

Doesnt support the latest versions of pdf

When tried to save a pdf form which is created using pdf 1.5 and above, it results in save error.

Unable to manual import in a swift project

Really nice work : thanks!

But I can't import it manually in my project (mainly swift but may not be related).

• I added ILPDFKit folder to my project (mainly swift project)
• I already use ARC
• I linked
  • UIKit
  • QuartzCore
  • CoreGraphic (seen it in project template)

I compare the template project and mine and don't see what is wrong.
The only difference is

• my project mainly swift

VERSUS

• template project : Objective C

=> I don't see the problem...

---

If someone had a try one day to import it manually in swift project, tell me (so that I will understand where I am wrong right now^^)

Adobe Acrobat cannot read many of the files created

After filling in some forms, I see this error in Adobe Acrobat when opening the PDF files:

"There was an error opening this document. The root object is missing or invalid."

Here is a link to a PDF form from around the Internet that do not work with ILPDFKit that show the above error:

http://www.stuart-design.co.uk/docs/Sample%20Fillable%20PDF%20Form.pdf

Here is another form that after I save it, I can view it in Preview but NOT in Adobe Acrobat:

http://www.thewebjockeys.com/TheWebJockeys/Fillable_PDF_Sample_from_TheWebJockeys_vC5.pdf

These are the very first two files that I tried - and neither of them currently works. Any idea what the issue might be?

Thanks!

Installation problems with cocoapods

Pod spec

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '7.0'
xcodeproj 'Test.xcodeproj'

If you open up the ILPDFKit folder while it's installing, you'll see the code downloading as it should but at the last phase it'll delete all the source files.

I have no idea why it'd do that.

Here's the terminal printout

Check Boxes...

Was wondering how would one program in a check for a checkbox?
I have tried:

[_pdfViewController.document.forms setValue:@"Yes" forFormWithName:@"Married"];
[_pdfViewController.document.forms setValue:@"YES" forFormWithName:@"Married"];
[_pdfViewController.document.forms setValue:@"1" forFormWithName:@"Married"];
[_pdfViewController.document.forms setValue:@"Y" forFormWithName:@"Married"];

But none of them added a check to the box. I have checked and double checked the form name thinking I may have typed it in wrong but it is correct.

Thanks

App crash because createWidgetAnnotationViewForPageView returns nil

Hi,

If the form has the ILPDFAnnotationFlagHidden, ILPDFAnnotationFlagInvisible o ILPDFAnnotationFlagNoView, createWidgetAnnotationViewForPageView returns nil. Later, the method updateWidgetAnnotationViews tries to add this nil view and add it to an array. The app crashes. Found using a pdf with those flags.

Thanks

Set fonts

Hi, is there a way to change the font (size etc.) within the single acroforms when setting the text programmatically? Thank you.

Font size for the text field in saved static PDF

I'm evaluating ILPDFKit with its sample app. I added a form which contains text fields with two different font sizes: 34 for the "label_title" field, while 16 for the others.

However, after filling out the form with the following code, and save it as static PDF, the resulting font sizes look different from the original ones.

Is there any way to make it follows the original font sizes? Alternatively, is there any way to set the font size problematically when filling out the form?

My form filling code:
`

    let document = ILPDFDocument(resource:"sample_form")

    document.forms.setValue("SAMPLE FORM", forFormWithName: "label_title")

    document.forms.setValue("From: ", forFormWithName: "label_from")

    document.forms.setValue("John Doe", forFormWithName: "field_from")

    document.forms.setValue("Subject: ", forFormWithName: "label_subject")

    document.forms.setValue("My Subject...", forFormWithName: "field_subject")

    document.forms.setValue("Message: ", forFormWithName: "label_body")

    document.forms.setValue("My Body...", forFormWithName: "field_body")

`

Image/Signature

How to manage Image or Signature ?
Currently we can update TextField and Checkboxes, but what about updating a placeholder for image or signature ?

Running on iPad

I'm running your project on an iPad with iOS 7.1 and I can't save any of your pdf files. Everything works in the simulator.

I get the Object Stream error.

Rendering of Form Fields are off on Multiple Pages

Not sure if this library is still being developed/supported but I just noticed that when you render a PDF form with text boxes on multiple pages the boxes seems to be offset. For example on the first page everything is 100% perfect. However the second page the boxes are all slightly offset, third page even more so, etc. My guess is that the way it calculates the y margin might be a bit off as you add more pages. just curious if anyone has run into this issue. I'm on IOS 8 so not sure if it was an issue with previous versions (iPad/iPad mini/iPhone same issue). I'm trying to narrow down problem and will post if I figure anything out

Crash while opening a PDF with Forms

For the most cases I'm able to open PDF with forms, but for a special file the app is crashing because of

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM objectForKeyedSubscript:]: unrecognized selector sent to instance

If find out that the ILPDFFormContainer is the reason for that. Especially in the populateNameTreeNode: method you expect a NSMutableDictionary, but in my case here it is an array:

   ...
    NSMutableDictionary *dict  = node[base];  // here in the dict var there comes an array and not dictionary, the base is "1" as STRING
    if (dict == nil) {
        dict = [NSMutableDictionary dictionary];
        node[base] = dict;
    }
    [self populateNameTreeNode:dict withComponents:[components subarrayWithRange:NSMakeRange(1, [components count]-1)] final:final];

My bad solution was it to check for the class, and in case that it is not a dictionary I don't populate:

    NSMutableDictionary *dict  = node[base];
    if (dict == nil) {
        dict = [NSMutableDictionary dictionary];
        node[base] = dict;
    }
    if ([dict isKindOfClass:[NSMutableDictionary class]])
    {
        [self populateNameTreeNode:dict withComponents:[components subarrayWithRange:NSMakeRange(1, [components count]-1)] final:final];
    }

Printing file with non-uniform page sizes results in forms offset incorrectly

Consider using `ILPDF` prefix for classes instead of `PDF`

Change Form Text Field Font Size

I have a form in my project, and this form has some textfield. I modify the textfield using follow code and this works:

document.forms.setValue( "Name", forFormWithName: "LabourName")

However, i want to change the font size of the text field in the form , named "LabourName". I have tried to change the font size of the form to 16 in the PDF, but when i set the text field in the form using above code, the font size still remain unchanged. How can i modify the font size or other property like bold words in text field? Thanksss.

Can't read text in parsed PDFs (weird encoding)

I'm using ILPDFKit to extract some text from some PDF files generated by another iOS app. Now I'm having some issues with the encoding of the text in certain files. I convert the Contents stream of an ILPDFPage into a string, then look for BT / ET pairs to extract the text.

For instance, one file contains the following text stream:

BT 0.03260000 Tc 7 0 0 7 0 0 Tm /Tc1 1 Tf [ (Las) 4 (t Name) ] TJ ET

from which I can easily extract the string Last Name

In another file (which has the same general format of the previous file, and which renders correctly on screen), I see the following string instead:

BT 0.03260000 Tc 7 0 0 7 0 0 Tm /TT2 1 Tf [ (!\"#) 4 ($%&\"\'\\() ] TJ ET

Why do I see those weird characters instead of the text Last Name? What am I doing wrong?

The only difference between the two files, apparently, is that one was created on iOS 9, the other was created on iOS 10.

Can't add ILPDFKit to custom view

Dear
I am trying to display the PDF to custom view using ILPDFKit , not full screen view controller.
Let me know how can I use the ILPDFKit to display the PDF into custom view

Mark output file as readonly

Is there a way to mark the output file as readonly?
Anyway this is great, thanks!

Save over the original editable pdf?

As the topic, is that possible to save some inputs to editable pdf?

how to save the flatPDF within app

Can you educate me on how to save the flatPDF file within iOS app. My objective is to save the faltPDF file within app so that user can send this file via e-mail or airprint from the app.

Any help or guidance would really be appreciated

Regards,

Forms not showing for "Some kind of editable PDF"s

I have here some special kind of editable PDF which is editable in Preview app and other desktop apps (also on windows) but shown as read-only through this library.. can u suggest whats the issue?

itext.pdf

Closing app with an open ILPDFViewController displays blank PDF on re-entry.

If you are viewing a PDF, close the app with the Home button, then re-open the app- the PDF will change to a split half-black half-white screen.

It appears the app reopen flow calls into ILPDFViewController
calls

• (void)viewWillTransitionToSize
  which calls
  [self loadPDFView];
  which creates a new _pdfView = [[ILPDFView alloc] initWithDocument:_document];
  then adds it to the view with-
  [self.view addSubview:_pdfView];

Which I assume is causing the blank.

If I change the function to:

- (void)loadPDFView {
    [_pdfView removeFromSuperview];
    if (!_pdfView) {
        _pdfView = [[ILPDFView alloc] initWithDocument:_document];
    }
    [self.view addSubview:_pdfView];
}

It works.

Is it my implementation causing an issue? Or is this a viable fix.

Thanks for your work.

Fast Scrolling PDF - will showing forms on different page than original

while checking ILPDFKit framework/library with WKWebView instead of UIWebView will showing some textfields on diffrent page then expected page while fast scrolling through PDF.

Sample project crashes

Using the project on iOS 10.2 makes the project crash -
Getting a lot of these errors:
invalid AES padding.
invalid AES block size.

Finally get this
2016-12-17 23:17:03.155 ILPDFKitExample[60071:559333] -[__NSDictionaryM addObject:]: unrecognized selector sent to instance 0x608000640720

doesn't show annotations

First of all great library. I am working on adding annotations on a PDF with forms.. I am adding annotation in a PDF, but when opened through ILPDFKit they doesn't show up, but actually they are there..

Is there anything that you can help me ?

Check the sample PDF I have added an annotation here https://db.tt/6sqgvrul

Multi-Page PDF crashes when scrolling

I have a multi-page PDF that loads the first page however as soon as I scroll up to the second page it crashes the app and logs "Collection <__NSArrayM: 0x16084c530> was mutated while being enumerated."

How update a checkbox (PDFFormTypeButton)???

assuming form is a PDFFormTypeButton
on = [_pdfDocument.forms setValue:@"1" forFormWithName:form.name];??
off = [_pdfDocument.forms setValue:@"0" forFormWithName:form.name];??
seems do not work

All form fields are on the first page

Hi,

When I put in a multi page form with fields set in Adobe Acrobat DC, all the fields are on page 1 of 5 and there are no fields on pages 2-5. Any idea why this happens and how I can fix it?

Font sizes are bigger than the font size it was created

Font sizes on savedpdf would render the fontsizes to a bigger size than it normally was set.

The scenario in this screenshot below is that we created a pdf then added forms using Adobe acrobat, the problem relies now on filling the form fields the output results in larger font than what was set in the PDF.

[ILPDFForm associatedWidget] returns nil

Date select field is considered as PDFTextField

I have date select field in my PDF and ILPDFKit considers that field as PDFFormType.Text.
When I'm setting value "01/11/16" to the field in PDF, ILPDFKit converts the value and prints it out as
"2016-01-11 01:13:36 +0000". Is there a way to just input "01/11/16" instead of "2016-01-11 01:13:36 +0000" ?

Form widget view Not working with autolayout and size classes

Black bars appear with 1.1.3

I found a new issue using 1.1.3, the latest update. The Viewer has black bars at the left and right border. I also tried another pdf file, but stil the same. See the screenshots below:

Version 1.1.1

Version 1.1.3

iOS 8 - app crashes

Unfortunately app crashes with iOS8.

Support for Checkboxes

It would be wonderful to be able to set checkboxes.

Some Forms are not placed to the proper page

I've experienced that with some PDF (created with Acrobat 9 PDF version 1.3) some forms are all placed in the first page instead of the correct page.

Investigating the PDF structure, I've noticed that in some Form Widgets the reference to the Parent object is not present.
Besides the Form Widget is referenced from the Page Annots: Catalogue -> Pages -> Annots

Keyboard Management

This is very cool software! Thanks for making it open source.

I have been evaluating it for only an hour. Is there keyboard management to avoid text fields on the bottom of the view controller from being covered by the keyboard?

Along the same lines, re-centering the view if a selected field is covered by the keyboard would also be a great enhancement.

I'll try to dig in further to see if these are enhancements I can code up and submit as pull requests.

Great work! I already love this project.

problem with the input in the textfield on a form

Whenever I want to add characters to a textfield field with content

1. Select textfield with content
2. go to a position within the existing contents
3. input of a character or words from the clipboard
   ...until here it works...
4. cursor jumps to the end of the entire content
   The problem:
   put on the marked can always be entered only one character. then the cursor jumps immediately to the end home.

All form data repeating on all pages

It seems that for the form I am testing all form data from each page is being rendered simultaneously on all pages. Is this what happens with flattenedData? Is there a way to address this?

Issue with Parse server

I have been trying to upload a form that I edited with ILPDF on the Parse server but all it uploads is a blank one paged pdf.

What program did you use to create PDF form?

I used adobe acrobat pro to create a new form to test out in the example program and only the radio buttons are coming up as fillable. I'm wondering if you did anything special to make ALL the fields show up so that I can fill them in on a custom form. Thanks!

Zooming causes text fields to truncate

If I enter text like "1234.56" into a small text field so that the text fills up all of the available space, for the most part the size of the text auto-shrinks to fill the available space. However, that functionality breaks when I zoom in and out - at some zoom levels the font size is too large and the field value is truncated to something like "123...". At other zoom levels the text is not truncated. Any ideas for a fix?

Crash on rotation

I've added a PDFViewController to a child container view:

let pdfVC = PDFViewController(path: path)
addChildViewController(pdfVC)
pdfVC.view.frame = containerView.bounds
containerView.addSubview(pdfVC.view)
pdfVC.didMoveToParentViewController(self)

And on rotation in ios8, a crash with no debug information occurs.

It seems to happen on _pdfView = nil in PDFViewController.m.

Sequence Protocol

Hi, when trying to iterate through the form container I get:
Type 'ILPDFFormContainer?' does not conform to protocol 'Sequence'
Any thoughts?

I get a crash in simulator when trying the example's "Save Static PDF"

am I the only one ?
