PDF را از تصویر(ها) از طریق Swift API تولید کنید

public enum PDFPage {
    case whitePage(CGSize) // = A white view
    case view(UIView)
    case image(UIImage)
    case imagePath(String)
    case binary(Data)
    case imageRef(CGImage)
}

func generatePDF() {
    let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
    v1.backgroundColor = .red
    let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
    v2.backgroundColor = .green

    let page1 = PDFPage.View(v1)
    let page2 = PDFPage.View(v2)
    let page3 = PDFPage.WhitePage(CGSizeMake(200, 100))
    let page4 = PDFPage.Image(UIImage(contentsOfFile: "path/to/image1.png")!)
    let page5 = PDFPage.ImagePath("path/to/image2.png")
    let pages = [page1, page2, page3, page4, page5]

    let dst = NSTemporaryDirectory().appending("sample1.pdf")
    do {
        try PDFGenerator.generate(pages, to: dst)
    } catch (let e) {
        print(e)
    }
}

چگونه PDF با رمز عبور از طریق Swift تولید کنیم؟

// generate PDF with password: 123456
func generatePDF() {
    let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
    v1.backgroundColor = .red
    let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
    v2.backgroundColor = .green

    let page1 = PDFPage.view(v1)
    let page2 = PDFPage.view(v2)
    let pages = [page1, page2]

    let dst = NSTemporaryDirectory().appending("sample1.pdf")
    do {
        try PDFGenerator.generate(pages, to: dst, password: "123456")
        // or use PDFPassword model
        try PDFGenerator.generate(pages, to: dst, password: PDFPassword("123456"))
        // or use PDFPassword model and set user/owner password
        try PDFGenerator.generate(pages, to: dst, password: PDFPassword(user: "123456", owner: "abcdef"))
    } catch let error {
        print(error)
    }
}

فایل PDF سفارشی DPI را با استفاده از Swift API

// generate dpi300 PDF (default: 72dpi)
func generatePDF() {
    let v1 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 100.0))
    v1.backgroundColor = .red
    let v2 = UIView(frame: CGRect(x: 0.0,y: 0, width: 100.0, height: 200.0))
    v2.backgroundColor = .green

    let page1 = PDFPage.View(v1)
    let page2 = PDFPage.View(v2)
    let pages = [page1, page2]

    let dst = NSTemporaryDirectory().appending("sample1.pdf")
    do {
        try PDFGenerator.generate(pages, to: dst, dpi: .dpi_300)
    } catch (let e) {
        print(e)
    }
}
