iOS PDF套件 - 完整尺寸页面

Question

我想创建一个具有完整尺寸页面的PDF文档。它不会填写整个页面。我该如何修复。

class PDFAssortmentExporter: NSObject {
        
    var metaDataPDF: PDFMetaData
    lazy var pageWidth : CGFloat  = {
        return 11 * 72.0
    }()

    lazy var pageHeight : CGFloat = {
        return 8.5 * 72.0
    }()

    lazy var pageRect : CGRect = {
        CGRect(x: 0, y: 0, width: pageWidth, height: pageHeight)
    }()

    lazy var marginPoint : CGPoint = {
        return CGPoint(x: 10, y: 10)
    }()

    lazy var marginSize : CGSize = {
        return CGSize(width: self.marginPoint.x * 2 , height: self.marginPoint.y * 2)
    }()
    
    init(metaDataPDF: PDFMetaData) {
        self.metaDataPDF = metaDataPDF
    }
    
    func prepareData() -> Data {
        
        let pdfMetaData = [
            kCGPDFContextCreator: metaDataPDF.contextCreatorPDF,
            kCGPDFContextAuthor: metaDataPDF.authorPDF,
            kCGPDFContextTitle: metaDataPDF.contextTitle
        ]

        let format = UIGraphicsPDFRendererFormat() 
        format.documentInfo = pdfMetaData as [String: Any]
        
        let renderer = UIGraphicsPDFRenderer(bounds: pageRect, format: format)

        
        let data = renderer.pdfData { (context) in

        }
        
        return data
    }
}

将 pdfView 的显示模式更改为单页

pdfView.displayMode = .singlePage
pdfView.displayDirection = .vertical
pdfView.autoScales = true
//pdfView.minScaleFactor = pdfView.scaleFactorForSizeToFit
pdfView.usePageViewController(true, withViewOptions: nil)
