Convert HTML to PDF on iOS

Internet connection is not required when converting local HTML files. However, it is required for converting HTTP/HTTPS links.

The platform-specific conversion API also supports HTML to PDF conversion, either with the +convertOfficeToPDF:paperSize:completion: method for .html files or the +convertHTMLStringToPDF:baseURL:paperSize:completion: for raw HTML text.

The following code shows how to convert an HTML string to PDF:

1PTConvert.convertHTMLString(toPDF: htmlString, baseURL: baseURL, paperSize: .zero) { (pathToPDF) in
2    guard let pathToPDF = pathToPDF else {
3        // Failed to convert HTML to PDF.
4        return
5    }
6    
7    // Copy temporary PDF to persistent location.
8    let documentDirectory = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, false)[0]
9    
10    let urlToPDF = URL(fileURLWithPath: pathToPDF)
11    let destinationURL = URL(fileURLWithPath: documentDirectory).appendingPathComponent(urlToPDF.lastPathComponent)
12    
13    do {
14        try FileManager.default.copyItem(at: urlToPDF, to: destinationURL)
15    } catch {
16        // Failed to copy item to persistent location.
17    }
18
19    // Do something with PDF output.
20}

where baseURL is the URL to use as the page's base URL for resolving relative links in the document.
