UIView's viewPrintFormatter is not able to create PDF - ios

Question

Note : UIWebView to PDF working for me.
Now UIView to PDF is also option but wanted to work with below code as same as used to create PDF in UIWebView.
I have done below code so far for UIView's viewPrintFormatter to be able create PDF:
Added Category of UIPrintPageRenderer for getting PDF Data
#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
Add these define for A4 size
#define kPaperSizeA4 CGSizeMake(595.2,841.8)
Create PDF
UIPrintPageRenderer *render = [[UIPrintPageRenderer alloc] init];
[render addPrintFormatter:self.view.viewPrintFormatter startingAtPageAtIndex:0];
//increase these values according to your requirement
float topPadding = 10.0f;
float bottomPadding = 10.0f;
float leftPadding = 10.0f;
float rightPadding = 10.0f;
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"];
NSData *pdfData = [render printToPDF];
if (pdfData) {
[pdfData writeToFile:[NSString stringWithFormat:#"%#/tmp.pdf",NSTemporaryDirectory()] atomically: YES];
}
else
{
NSLog(#"PDF couldnot be created");
}
