पीडीएफ प्रोग्रामेटिक रूप से

Question

बनाने के लिए नमूना कोड मैं आईफोन के लिए नया हूं।

क्या कोई नमूना कोड या ट्यूटोरियल है।

प्लिस्ट

के लिए नमूना कोड की भी आवश्यकता है कृपया मेरी मदद करें।

आप कर सकते हैं बनाने के लिए सबसे अच्छा उदाहरण है इसे थोड़ा उन्नत ट्यूटोरियल ढूंढें लेकिन this ठीक तुतीरी रे वेंडरलिच द्वारा अल वास्तव में आपकी मदद करेगा और जहां तक ​​प्लेट संबंधित है, आपको Google को पहले यह करना चाहिए क्योंकि आप उनमें से बहुत कुछ पा सकते हैं।

एप्पल के Drawing and Printing Guide अपने दोस्त है। असल में, यदि आप स्क्रीन पर आकर्षित कर सकते हैं, तो आप आईओएस (और मैक ओएस एक्स) पर एक पीडीएफ में आकर्षित कर सकते हैं।

Answer 4

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), 
                CGContextGetClipBoundingBox(context)); 

      CGContextConcatCTM(context, transform); 
      UIGraphicsBeginImageContext(CGSizeMake(self.bounds.size.width, self.bounds.size.height));
