推荐答案

用于创建多个页面

在.m文件的顶部定义 NSInteger currentPage = 0;

Define NSInteger currentPage = 0; at the top in .m file

和generatePdfWithFilePath方法写

and in generatePdfWithFilePath method write

-(void) generatePdfWithFilePath: (NSString *)thefilePath
{
    NSLog(@"\n==========\n \t the file path==  %@",thefilePath);

    UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);

    do
    {        
           currentPage++;

           if(currentPage == 1) 
              pageSize= CGSizeMake(612,2350);
           else
              pageSize = CGSizeMake(612, 2000);

           [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];

    }while (currentPage !=2); //You can write required page number here

    currentPage=0;

    UIGraphicsEndPDFContext();
}
