How to create a PDF file in Xamarin.iOS?

PDF (Portable Document Format) is the file format used to display the document with same formatting, independent of application software, hardware, and operating system. Syncfusion Essential PDF is a .NET PDF library used to create, read, and edit PDF documents. Using this library, you can create a PDF document in Xamarin.iOS.

 

Steps to create PDF programmatically:

 

  1. Create a new C# Xamarin iOS application project.

 

 

  1. Select a project template, minimum iOS version, and device support for the application.

 

 

  1. Install the Syncfusion.Xamarin.Pdf NuGet package as reference to your .NET Framework applications from NuGet.org.

 

 

  1. In the project, add new UIViewController class.

 

 

  1. In AppDelegate.cs, add the following code on FinishedLaunching() to load the UIViewController1 at top of the window.

 

 

  1. In UIViewController1.cs, add the following code in the ViewDidLoad() method to add the button in the UIView.

 

 

  1. Include the following namespace in the UIViewController1.cs file.

 

  1. In the click event method (OnButtonClicked), add the following code to create a PDF file and save it in a stream.

 

 

  1.  Add the SaveIOS class to the project, where the stream will be saved to a physical file and the file can be opened for viewing. Refer to the following code.

 

 

Note: To preview the PDF document in QuickLook, add the PreviewControllerDS, QLPreviewItemFileSystem, and QLPreviewItemBundle classes in the project. The code for these helper classes can be found from this link (iOS -> PreviewControllerDS.cs).

 

  1. Compile and execute the application. Now, this application creates a simple PDF document.

 

A complete working sample can be downloaded from Create-PDF-file.zip

 

Take a moment to peruse the documentation, where you can find other options like drawing right-to-left text and multi-column text,  consuming TrueType fonts, Standard fonts and CJK fonts. Also, the features like PDF form filling, extract text or images from PDF, and protect PDF documents with code examples.
