用于创建、操作和转换 PDF 的 Swift REST SDK

通过 CocoaPods 安装 Aspose.PDF Cloud Swift SDK

 //First install CocoaPods

$ gem install cocoapods

// To integrate AsposePdfCloud into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!

target '' do
    pod 'AsposePdfCloud', '~> 20.12'
end

// Run the following command to complete the process
$ pod install

You can also download it directly from Aspose PDF product page.

通过 Swift API 从 XML 创建简单的 PDF 文件

func createPDF(fromXML xmlData: Data, outputPath: String) {
    // Parse the XML data and extract the relevant content and formatting information
    
    // Create a PDF context
    UIGraphicsBeginPDFContextToFile(outputPath, CGRect.zero, nil)
    
    // Start a new PDF page
    UIGraphicsBeginPDFPage()
    
    // Draw the PDF content using Core Graphics
    // ...
    
    // End the PDF context and save the file
    UIGraphicsEndPDFContext()
}

通过 Swift API 将 PDF 文件转换为 PPTX

 import AsposePdfCloud

// Set up credentials
let clientId = "your_client_id"
let clientSecret = "your_client_secret"
let apiBaseUrl = "https://api.aspose.cloud"
let config = Configuration(clientId: clientId, clientSecret: clientSecret)
let api = PdfApi(configuration: config)

// Convert PDF to PPTX
let fileName = "input.pdf"
let destFileName = "output.pptx"
let format = "pptx"
let outputFolder = "output"
let storage = "your_storage_name"
let folder = "your_folder_name"

let request = PostPdfInRequest(document: InputStream(data: pdfData), format: format, folder: folder, storage: storage, outPath: outputFolder+"/"+destFileName)
let response = try api.postPdfIn(request: request)

// Download converted file
let downloadRequest = GetDownloadFileRequest(path: response.path!)
let downloadResponse = try api.downloadFile(request: downloadRequest)
let pptxData = downloadResponse.body

如何使用 Swift 命令获取 PDF 页面注释？

// Get your ClientId and ClientSecret from https://dashboard.aspose.cloud (free registration required).

	let pdfAPI = PdfAPI(clientId: "MY_CLIENT_ID", clientSecret: "MY_CLIENT_SECRET");
	let pageNumber = 2
	pdfAPI.getPageAnnotations(name: name, pageNumber: pageNumber, folder: self.tempFolder) {
		(response, error) in
		guard error == nil else {
			// errror handle
			return
		}
		if let response = response {
			// do
		}
	}

通过 Swift API 加密 PDF 文档

import AsposePDFCloud

let config = Configuration()
config.appKey = "your_app_key"
config.appSID = "your_app_SID"

let pdfApi = PdfApi(configuration: config)

let encryptOptions = EncryptDocument(
    encryptionAlgorithm: EncryptionAlgorithm.aes,
    ownerPassword: "owner_password",
    permissions: Permissions.allowAll,
    userPassword: "user_password")

let localFile = "local_file.pdf"

let encryptedFile = "encrypted_file.pdf"

pdfApi.putEncryptDocument(
    name: localFile,
    encryption: encryptOptions,
    outPath: encryptedFile) { (response, error) in
        if let error = error {
            print("Error while encrypting document: \(error)")
        } else {
            print("Document encrypted successfully.")
        }
}
