Cordova Wrapper for PSPDFKit 7 for iOS

The PSPDFKit SDK is a framework that allows you to view, annotate, sign, and fill PDF forms on iOS, Android, Windows, macOS, and Web. PSPDFKit Instant adds real-time collaboration features to seamlessly share, edit, and annotate PDF documents.

PSPDFKit comes with open source wrappers for Cordova on both iOS and Android.

This plugin works with Cordova version 6.3.1 and above.
Please also make sure that you're using the latest version of Xcode 9.

Install

We assume you have a current install of Cordova.

cordova plugin add https://github.com/PSPDFKit/Cordova-iOS.git

Read the message at the end and complete installation.

You will need to manually edit the Xcode project and add PSPDFKit to your project manually. There is no automatic support for dynamic frameworks in Cordova yet. You will get a linker error if you forget this step.

Note: Make sure to follow our integration guide to strip the framework, working around an App Store submission bug.

Demo

You can find a demo app in CordovaDemo.

In order to build it, please download PSPDFKit from your customer portal: https://customers.pspdfkit.com
The .dmg file you downloaded contains two directories called PSPDFKit.framework and PSPDFKitUI.framework.
Please copy these directories to CordovaDemo/platforms/ios.

You can set your license key in CordovaDemo/www/js/index.js.
(Look for PSPDFKitPlugin.setLicenseKey('YOUR KEY');)

After that, you can build the demo app with $ cordova build.
To run the demo app in the simulator use $ cordova emulate.

Ionic

1. Create Ionic app Cordova plugin (replace IonicDemo with your app's name): ionic start IonicDemo blank --cordova
2. Go into your app's folder: cd IonicDemo
3. Add iOS platform: ionic cordova platform add ios
4. Add PSPDFKit plugin: ionic cordova plugin add https://github.com/PSPDFKit/Cordova-iOS.git
5. Follow the instructions after adding the PSPDFKit plugin (manually edit the Xcode project)
6. Declare PSPDFKitPlugin in src/declarations.d.ts (create this file first): declare var PSPDFKitPlugin: any;
7. Present PDF by modifying src/app/app.component.ts:

constructor(platform: Platform, statusBar: StatusBar, splashScreen: SplashScreen) {
    platform.ready().then(() => {
      // Okay, so the platform is ready and our plugins are available.
      // Here you can do any higher level native things you might need.
      statusBar.styleDefault();
      splashScreen.hide();

      PSPDFKitPlugin.setLicenseKey('YOUR KEY');
      PSPDFKitPlugin.present('pdf/document.pdf', {});
    });
}

1. Place your document.pdf in the www/pdf subdirectory.
2. Try out your app: ionic cordova emulate ios

Troubleshooting

Problem:

Error: Cannot find plugin.xml for plugin "Cordova-iOS". Please try adding it again.

Solution:

Run cordova plugin add https://github.com/PSPDFKit/Cordova-iOS.git instead of ionic cordova plugin add https://github.com/PSPDFKit/Cordova-iOS.git.

Ionic Demo

You can find an Ionic demo app in IonicDemo.

1. Go into the demo app's directory: cd IonicDemo
2. Prepare the app: ionic cordova prepare
3. Follow the instructions that are shown after the PSPDFKit plugin gets added (manually edit the Xcode project)
4. Set your license key in IonicDemo/src/app/app.component.ts (look for PSPDFKitPlugin.setLicenseKey('YOUR KEY');)
5. Put a PDF document into www/pdf/document.pdf
6. Build the app with ionic cordova build ios and run it with ionic cordova emulate ios

Usage

The plugin is accessed via the PSPDFKitPlugin singleton. Here are some example calls:

// set your license key here
PSPDFKitPlugin.setLicenseKey("YOUR KEY");

//show pdf with in double page mode, with curl transition red background
PSPDFKitPlugin.present('pdf/castles.pdf', {
    pageTransition : 'curl',
    pageMode: 'double',
    backgroundColor: 'red'
});

//show pdf with callback
PSPDFKitPlugin.present('pdf/castles.pdf', function() {
    alert('pdf has appeared');
});

//scroll to page 1
PSPDFKitPlugin.setPage(1, true);

//get the page number
PSPDFKitPlugin.getPage(function(page) {
    alert('Current page: ' + page);
});

Functions

The plugin functions currently implemented are:

present(path, [callback], [options]);

Displays a PDF in a full-screen modal. The path should be a string containing the file path (not URL) for the PDF. Relative paths are assumed to be relative to the www directory (if the page has a different base URL set, this will be ignored). To specify a path inside the application documents or library directory, use a , e.g. "/Documents/mypdf.pdf" or "~/Library/Application Support/mypdf.pdf". Path can be null, but must not be omitted

The options parameter is an optional object containing configuration properties for the PDF document and/or view controller. All currently supported values are listed below under Options.

The optional callback will be called once the PDF controller has fully appeared on screen. Calling present() when there is already a PDF presented will load the new PDF in the current modal (in which case the callback will fire immediately).

dismiss([callback]);

This method dismisses the modally presented PDF view. The optional callback will be called once the PDF controller has dissapeared from the screen.

reload();

This method reloads the current PDF.

search(query, [animated], [headless]);

This method triggers a search for the specified query text. The optional animated argument determines if the search should be animated (if omitted, the search will not be animated). The optional headless argument determines whether the search UI should be disaplyed (if omitted, the search UI will be displayed).

saveAnnotations(callback(error));

This method saves any changed annotations in the current or last opened document. On success the error callback parameter will be null, on failure it will be an object containing an error domain, code, and (possibly) a description and reason.

setOptions(options, [animated]);

This method can be used to set multiple document and view controller settings at once. The options set will be applied to the current document (if there is one) as well as all subsequently displayed documents. All currently supported values are listed below under Options. The optional animated argument determines if the property should be animated. Not all property changes can be animated, so if the property does not support animation the animated argument will be ignored.

getOptions(names, callback(values));

This method can be used to get several document or view controller options in a single call. The first argument is an array of option names, the second is a callback that will receive an object containing all the specified values by name. All currently supported values are listed below under Options.

setOption(name, value, [animated]);

This method can be used to set a single document or view controller option. All currently supported values are listed below under Options. The optional animated argument determines if the property should be animated. Not all property changes can be animated, so if the property does not support animation the animated argument will be ignored.

getOption(name, callback(value));

This method can be used to get a single document or view controller option. The first argument is the option name, the second is a callback that will receive the value. All currently supported values are listed below under Options.

addEventListener(type, callback(event));

This method adds an event listener callback function for a specific event type. The list of possible event types is listed below under events. The callback will receive a single parameter called event, which will always contain the type and may contain other parameters, depending on the event type.

Some events expect a boolean return value. If a value is not returned for these events, the return value is assumed to be true. Returning false from any event listener will prevent any subsequent listeners on that event from being called.

Note that although this API is designed to mimic the standard DOM event binding mechanism as much as possible, the event parameter is not a true event, and features such as capturing or bubbling are not supported.

addEventListeners(listeners);

This method allows you to add several event listeners at once. The listeners argument is an object containing listener functions keyed by event type. Note that it is not possible to bind multiple functions to a single event type with a single call.

removeEventListener(type, listener);

This method unbinds the specified event listener function from the specified event.

setPage(page, [animated]);

This method will scroll to the specified page (0-indexed). The optional animated argument determines if the scroll should be animated (if omitted, the scroll will not be animated).

getPage(callback(page));

This method returns the current page (0-indexed). The page will be returned as the first argument to the callback function provided. The function itself returns no value.

getPageCount(callback(count));

This method returns the total page count. The page count will be returned as the first argument to the callback function provided. The function itself returns no value.

scrollToNextPage([animated]);

Scrolls to the next page. The optional animated argument determines if the scroll should be animated (if omitted, the scroll will not be animated).

scrollToPreviousPage([animated]);

Scrolls to the previous page. The optional animated argument determines if the scroll should be animated (if omitted, the scroll will not be animated).

setLeftBarButtonItems(items);
setRightBarButtonItems(items);

These methods allow you to configure the toolbar items for the PDF viewer. The items should be supplied as an array. Each element in the array should be either a string representing a standard toolbar item (see Standard toolbar items below for a list of supported values) or an object with the format specified below.

You can optionally set these toolbar buttons using the setOption(s) functions, or the options parameter of the present() function by using the keys leftBarButtonItems and rightBarButtonItems.

getLeftBarButtonItems(callback(items));
getRightBarButtonItems(callback(items));

These methods retrieve the current left and right toolbar items arrays.

toggleAnnotationToolbar();
showAnnotationToolbar();
hideAnnotationToolbar();

These methods control the display of the annotation toolbar.

Custom toolbar button format

Custom toolbar buttons should be specified as an object in the following format:

{title: 'Hello', action: function() {
    //do something
}};

You can optionally include the following values:

style

A string with a value of 'bordered', 'plain', or 'done', indicating the button style. The default style is 'bordered'.

tintColor

A css color value. This will control the toolbar button tint color.

image
landscapeImage

A path to an image to display in the toolbar button. If landscapeImage is omitted it is assumed to be the same as image This path should be relative to the www folder (absolute paths, or paths outside of the application resources are not supported).
