Advances in Hybrid Wrappers

At PSPDFKit, we support all major hybrid technologies, and as part of our quest to continuously improve our wrappers, we’ve added new APIs, improved existing ones, and fixed several issues.

In this article, we’ll highlight the recent advances made to our hybrid wrappers.

ℹ️ Note: This blog post was updated on 22 July 2021 to remove mentions of Titanium, as Axway announced End-of-Support for the Titanium SDK effective 1 March 2022.

React Native

Our React Native wrapper is very popular, and the community contributing to it is very active. Over the last few months, we’ve fixed many issues, made some considerable improvements, and exposed a lot of native APIs. Here are some notable changes from our recent releases:

• Added the toolbarTitle configuration property to override the iOS toolbar title.

• Added the onDocumentLoadFailed callback on Android and iOS.

• Added JavaScript APIs to customize the toolbar on iOS.

• Added the getAllAnnotations() JavaScript API to query all annotations from a document.

• Improved error handling for annotation manipulation functions on iOS.

• Improved document path resolution on Android.

• Updated the iOS integration steps to use CocoaPods by default.

• Fixed a memory leak issue in React Native for Windows with Newtonsoft.

For the full set of changes, please take a look at our recent releases here.

Cordova and Ionic

Our Cordova plugin is also very widely used. We’ve made some significant improvements and we exposed several native Android and iOS APIs to JavaScript:

• Added the ability to manipulate annotations programmatically.

• Added the programmatic forms API.

• Added the ability to import and export XFDF.

• Added document-processing APIs.

We also released a brand new and unified Cordova plugin for both Android and iOS. Take a look at our announcement blog post for more details.

Flutter

Flutter is the youngest of our wrappers, and we are seeing it gain a lot of popularity among our customers and partners. Here are a few highlights of our recent improvements:

• Added the ability to manipulate annotations programmatically.

• Added the ability to manipulate forms programmatically.

• Added the ability to programmatically unlock password-protected documents.

• Added the showDocumentTitle configuration option to allow users to toggle the visibility of the document title.

• Added the ability to customize the toolbar buttons on iOS.

• Extended support for styling and configuration options.

• Exposed various configuration options like showDocumentLabel, settingsMenuItem, and more.

Electron and Xamarin

We’ve also updated our Electron and Xamarin wrappers to make sure they are fully compatible with the latest versions of PSPDFKit, tools, and operating systems.
