我想写一个简单的PDF阅读器,使用基于QuartzDemo的CGPDFDocument。
有共同的描绘:(EX在触摸事件)iPhone,CGPDFDocument - PDF链接
-(void)drawInContext:(CGContextRef)context
{
// PDF page drawing expects a Lower-Left coordinate system,
// so we flip the coordinate system before we start drawing.
CGContextTranslateCTM(context, 0.0, self.bounds.size.height);
CGContextScaleCTM(context, 1.0, -1.0);
// Grab the first PDF page
CGPDFPageRef page = CGPDFDocumentGetPage(pdf, pageNumber);
// We're about to modify the context CTM to draw the PDF page
// where we want it, so save the graphics state
// in case we want to do more drawing
CGContextSaveGState(context);
// CGPDFPageGetDrawingTransform provides an easy way
// to get the transform for a PDF page. It will scale down to fit,
// including any base rotations necessary to display the PDF page correctly.
CGAffineTransform pdfTransform =
CGPDFPageGetDrawingTransform(page,
kCGPDFCropBox, self.bounds, 0, true);
// And apply the transform.
CGContextConcatCTM(context, pdfTransform);
// Finally, we draw the page
// and restore the graphics state for further manipulations!
CGContextDrawPDFPage(context, page);
CGContextRestoreGState(context);
}
据我了解,它唯一的图纸,所以所有的结构导航或外向链接,应手工处理。有功能which will set URL或create element with URL。
问题是:如何从某个PDF块中获取传出链接URL?
谢谢!
