iphone - プログラムでPDFを作成するサンプルコード

Question

iphone初心者です。

サンプル コードまたはチュートリアルはありますか。

plistのサンプルコードも必要

私を助けてください。

Answer 1

ここに私はiPhoneで.pdfファイルを作成する方法の最良の例を持っています:)

PdfGenerationDemoViewController.h

#import <UIKit/UIKit.h>

#define kBorderInset            20.0
#define kBorderWidth            1.0
#define kMarginInset            10.0

//Line drawing
#define kLineWidth              1.0

@interface PdfGenerationDemoViewController : UIViewController
{
    CGSize pageSize;
}

- (IBAction)generatePdfButtonPressed:(id)sender;

@end

PdfGenerationDemoViewController.m

#import "PdfGenerationDemoViewController.h"

Appleの描画および印刷ガイドはあなたの友達です。基本的に、画面に描画できる場合は、iOS（およびMac OS X）でPDFに描画できます。

Answer 3

あなたはそれを少し高度なチュートリアルに見つけるかもしれませんが、レイ・ウェンダーリッヒによるこの素晴らしいチュートリアルは本当にあなたを助けます、そしてプリットに関する限り、あなたはそれらをたくさん見つけることができるので最初にそれをグーグルするべきです。

幸運をお祈りしています、

CFURLRef pdfURL = CFBundleCopyResourceURL(CFBundleGetMainBundle(), CFSTR("iPhoneAppProgrammingGuide.pdf"), NULL, NULL);
        PDFfile = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
        CFRelease(pdfURL);    
 CGPDFPageRef page = CGPDFDocumentGetPage(PDFfile,currentpage);

        context = UIGraphicsGetCurrentContext();
        CGContextSaveGState(context);
        CGContextSetRGBFillColor(context, 1.0, 1.0, 1.0, 1.0);
        CGContextFillRect(context,self.bounds);   
        CGContextTranslateCTM(context, -1.0, [self bounds].size.height);
        CGContextScaleCTM(context, 1.0, -1.0);
        CGContextConcatCTM(context, CGPDFPageGetDrawingTransform(page,  kCGPDFArtBox, [self bounds], 0, true));
        CGContextDrawPDFPage(context, page);    
        CGContextRestoreGState(context);
        CGAffineTransform transform = aspectFit(CGPDFPageGetBoxRect(page, kCGPDFMediaBox),
