Question

我使用这种方式生成pdf文件现在它工作正常但背景为白色我想给背景一些颜色，所以可以给backgorund颜色。

  - (void) generatePdfWithFilePath: (NSString *)thefilePath

  {
  UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);


 NSInteger currentPage = 0;
 BOOL done = NO;
 do 
  {

    UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, pageSize.width, pageSize.height), nil);


    currentPage++;
    [self drawPageNumber:currentPage];

    //Draw a border for each page.
    [self drawBorder];

    //Draw text fo our header.
    [self drawHeader];

    //Draw a line below the header.
    [self drawLine];

    //Draw some text for the page.
    [self drawText];

    //Draw an image
    [self drawImage];
    done = YES;


     } 
  while (!done);


 UIGraphicsEndPDFContext();
}

Answer 1

在do while循环中使用此代码

CGContextRef currentContext = UIGraphicsGetCurrentContext();
CGContextSetFillColorWithColor(currentContext, [UIColor redColor].CGColor );
CGContextFillRect(currentContext, pdfpageFrame);
