How to Open a PDF in Adobe Acrobat Instead of iOS Default Viewer
Question details
The user needs to know how to configure an Ionic iOS app to open form-filled PDFs in Adobe Acrobat Reader instead of relying on the system's default PDF viewer.
- Product
- Ionic iOS App
- Device & OS
- iOS
- Scenario
- A user is trying to view a form-filled PDF generated or downloaded within an Ionic iOS app and wants to use Adobe Acrobat Reader for full compatibility.
- Observed behavior
- The Ionic app automatically opens the PDF in the iOS default viewer, as iOS restricts applications from forcing documents to open directly in third-party apps without user interaction.
Ensure you have access to the Ionic application's source code and are familiar with implementing native iOS document interaction or sharing APIs.
Implement a Share or 'Open In' Workflow
Because iOS does not allow an app to bypass user choice and force open a third-party application, you must implement a sharing workflow to let users send the PDF to Adobe Acrobat Reader.
To allow users to view their PDFs in Adobe Acrobat, developers must integrate iOS sharing functions. This relies on the iOS document interaction controller or the UI activity view controller, providing the user with a standard system menu to select their preferred PDF reader.
Integrate the iOS Document Interaction Controller (UIDocumentInteractionController) or UIActivityViewController into your Ionic app using a suitable Cordova or Capacitor plugin.
Ensure the downloaded or form-filled PDF is saved locally on the device, and pass the compatible local file URL or data object to the sharing API.
Create an 'Open In' or 'Share' button in your application's user interface that triggers the document interaction API when tapped.
When the iOS share sheet appears on the screen, instruct the user to scroll through the application list and select 'Adobe Acrobat Reader' to complete the handoff.
Edit and Fill PDF Forms with WPS Office on iOS
Need a powerful and lightweight alternative for handling PDF forms on your mobile device? WPS Office provides seamless PDF viewing, form filling, and editing capabilities on iOS, alongside full compatibility with Microsoft Word, Excel, and PowerPoint formats.
- 1. Install WPS Office: Download and install WPS Office for free from the Apple App Store.
- 2. Open the Share Sheet: Tap the 'Share' or 'Open In' button in your current application while viewing the PDF.
- 3. Select WPS Office: Choose WPS Office from the list of apps to accurately view and fill your PDF documents.
Frequently Asked Questions
Can I force iOS to open PDFs in Adobe Acrobat by default?
No, Apple's iOS platform does not allow users or developers to set a third-party app like Adobe Acrobat as the absolute system-wide default for opening PDFs. You must use the Share sheet or 'Open In' menu.
Why do form-filled PDFs display incorrectly in the iOS default viewer?
The native iOS PDF viewer lacks full support for advanced PDF forms, complex JavaScript, or specific XFA elements found in some interactive PDFs, which is why a dedicated reader like Adobe Acrobat or WPS Office is necessary.
How do users find Acrobat if it is missing from the iOS Share sheet?
When the Share sheet opens, users should scroll to the far right of the app icons, tap 'More' (the three dots), and toggle on Adobe Acrobat or WPS Office to add it to their sharing favorites.
