I want to show a NSAttributedString in a PDF document.
Creating the PDF is working well but there is only plain text without any attributes.
If I change:
CFAttributedStringRef currentText = CFAttributedStringCreateCopy(NULL,(__bridge CFAttributedStringRef)**enterText.text**);
to"
CFAttributedStringRef currentText = CFAttributedStringCreateCopy(NULL,(__bridge CFAttributedStringRef)**enterText.attributedText**);
the code is not working anymore.
Thats the code a actually wrote:
- (IBAction)createPDF:(id)sender {
//Get Document Directory path
NSArray * dirPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//Define path for PDF file
documentPath = [[dirPath objectAtIndex:0] stringByAppendingPathComponent:@"/Editortext.pdf"];
// Prepare the text using a Core Text Framesetter.
CFAttributedStringRef currentText = CFAttributedStringCreateCopy(NULL,(__bridge CFAttributedStringRef)enterText.text);
if (currentText) {
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(currentText);
if (framesetter) {
// Create the PDF context using the default page size of 612 x 792.
UIGraphicsBeginPDFContextToFile(documentPath, CGRectZero, nil);
CFRange currentRange = CFRangeMake(0, 0);
NSInteger currentPage = 0;
BOOL done = NO;
do {
// Mark the beginning of a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, 612, 792), nil);
// Draw a page number at the bottom of each page.
currentPage++;
[self drawPageNbr:currentPage];
// Render the current page and update the current range to
// point to the beginning of the next page.
currentRange = *[self updatePDFPage:currentPage setTextRange:¤tRange setFramesetter:&framesetter];
// If we're at the end of the text, exit the loop.
if (currentRange.location == CFAttributedStringGetLength((CFAttributedStringRef)currentText))
done = YES;
} while (!done);
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();
// Release the framewetter.
CFRelease(framesetter);
// [self pdfsenden];
} else {
NSLog(@"Could not create the framesetter..");
}
// Release the attributed string.
CFRelease(currentText);
} else {
NSLog(@"currentText could not be created");
}
}
-(CFRange*)updatePDFPage:(int)pageNumber setTextRange:(CFRange*)pageRange setFramesetter:(CTFramesetterRef*)framesetter
{
// Get the graphics context.
CGContextRef currentContext = UIGraphicsGetCurrentContext();
// Put the text matrix into a known state. This ensures
// that no old scaling factors are left in place.
CGContextSetTextMatrix(currentContext, CGAffineTransformIdentity);
// Create a path object to enclose the text. Use 72 point
// margins all around the text.
CGRect frameRect = CGRectMake(72, 72, 468, 648);
CGMutablePathRef framePath = CGPathCreateMutable();
CGPathAddRect(framePath, NULL, frameRect);
// Get the frame that will do the rendering.
// The currentRange variable specifies only the starting point. The framesetter
// lays out as much text as will fit into the frame.
CTFrameRef frameRef = CTFramesetterCreateFrame(*framesetter, *pageRange,
framePath, NULL);
CGPathRelease(framePath);
// Core Text draws from the bottom-left corner up, so flip
// the current transform prior to drawing.
CGContextTranslateCTM(currentContext, 0, 792);
CGContextScaleCTM(currentContext, 1.0, -1.0);
// Draw the frame.
CTFrameDraw(frameRef, currentContext);
// Update the current range based on what was drawn.
*pageRange = CTFrameGetVisibleStringRange(frameRef);
pageRange->location += pageRange->length;
pageRange->length = 0;
CFRelease(frameRef);
return pageRange;
}
Thanks for help!
