Is there any way to generate PDF file from a XML/HTML template in iOs

Question

I am creating an iPad application, in that i have to use different PDF forms. I got some methods to generate PDF files through code using Quartz2D. But I have to write entir

Answer 1

@TomSwift : agree with his answer but i would like to explain in better way

To be able create PDF from UIWebView is load HTML to yourWebView or there might be case yourWebView can also be hidden to generate PDF but process remains the same

1) Added Category of UIPrintPageRenderer for getting PDF Data as yourWebView.viewPrintFormatter need to be used

@interface UIPrintPageRenderer (PDF)
- (NSData*) printToPDF;
@end

@implementation UIPrintPageRenderer (PDF)
- (NSData*) printToPDF
{
  NSMutableData *pdfData = [NSMutableData data];
  UIGraphicsBeginPDFContextToData( pdfData, self.paperRect, nil );
  [self prepareForDrawingPages: NSMakeRange(0, self.numberOfPages)];
  CGRect bounds = UIGraphicsGetPDFContextBounds();
  for ( int i = 0 ; i < self.numberOfPages ; i++ )
  {
    UIGraphicsBeginPDFPage();
    [self drawPageAtIndex: i inRect: bounds];
  }
  UIGraphicsEndPDFContext();
  return pdfData;
}
@end

2) Add these define for A4 size or any custom size you want

#define kPaperSizeA4 CGSizeMake(595.2,841.8)

3) Process how we can create PDF

//create print renderer
UIPrintPageRenderer *render = [[UIPrintPageRenderer alloc] init];
[render addPrintFormatter:yourWebView.viewPrintFormatter startingAtPageAtIndex:0];

//provide padding ---- increase these values according to your requirement
float topPadding = 10.0f;
float bottomPadding = 10.0f;
float leftPadding = 10.0f;
float rightPadding = 10.0f;

//provide rect for printing and for actual PDF Rect of page
CGRect printableRect = CGRectMake(leftPadding,
                                  topPadding,
                                  kPaperSizeA4.width-leftPadding-rightPadding,
                                  kPaperSizeA4.height-topPadding-bottomPadding);
CGRect paperRect = CGRectMake(0, 0, kPaperSizeA4.width, kPaperSizeA4.height);
[render setValue:[NSValue valueWithCGRect:paperRect] forKey:@"paperRect"];
[render setValue:[NSValue valueWithCGRect:printableRect] forKey:@"printableRect"];

//category created above is used here 
NSData *pdfData = [render printToPDF];
//Save PDF to directory for usage
if (pdfData) {
  [pdfData writeToFile:[NSString stringWithFormat:@"%@/tmp.pdf",NSTemporaryDirectory()] atomically: YES];
}
else
{
  NSLog(@"PDF couldnot be created");
}
