Create Multi Page PDF with UIImage at the Bottom - ios

Question

I need to create a multipage PDF with signature (UIImage) at the bottom. I would also like to have a line created so that the signature could be on a line. Here's the code I have so far:
- (IBAction)saveAsPDF:(id)sender
{
NSMutableData *pdfData = [NSMutableData data];
UIGraphicsBeginPDFContextToData(pdfData, CGRectMake(0, 0, 612, 792), nil);
UIGraphicsBeginPDFPage();
[nameTextField.text drawInRect:CGRectMake(50, 40, 512, 30) withFont:[UIFont systemFontOfSize:16] lineBreakMode:NSLineBreakByWordWrapping alignment:NSTextAlignmentCenter];
[TextView.text drawInRect:CGRectMake(50, 90, 512, 672) withFont:[UIFont systemFontOfSize:12]];
[SignatureImageView.image drawInRect:CGRectMake(30, 500, 190, 71)];
UIGraphicsEndPDFContext();
NSArray* documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString* documentDirectory = [documentDirectories objectAtIndex:0];
NSString* documentNameWithExtention = [NSString stringWithFormat:#"%#.pdf", nameTextField.text];
NSString* documentDirectoryFilename = [documentDirectory stringByAppendingPathComponent:documentNameWithExtention];
[pdfData writeToFile:documentDirectoryFilename atomically:YES];
}
So, I need to know how to make it multipage and I need to know how to add the signature at the end of the body text.
Any help would be appreciated.

From the docs
The functions you use to create a PDF graphics context allow you to
specify a default page size but they do not automatically open a page.
After creating your context, you must explicitly open a new page using
either the UIGraphicsBeginPDFPage or UIGraphicsBeginPDFPageWithInfo
function. And each time you want to create a new page, you must call
one of these functions again to mark the start of the new page. The
UIGraphicsBeginPDFPage function creates a page using the default size,
while the UIGraphicsBeginPDFPageWithInfo function lets you customize
the page size and other page attributes.
