UIGraphicsBeginPDFPageWithInfo用来绘制PDF文档，可以绘制文字和图片。

    //PDF文件保存路径
    NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *pdfPath = [[documentPath firstObject] stringByAppendingString:@"/newPDF.pdf"];
    NSLog(@"%@", pdfPath);
    //开启PDF图形上下文
    /*
     path            文件路径
     bounds          PDF绘制尺寸，设置为CGRectZero则使用默认值612*912
     documentInfo    PDF文档信息
     */
    UIGraphicsBeginPDFContextToFile(pdfPath, CGRectZero, [NSDictionary dictionaryWithObjectsAndKeys:@"MacPen",kCGPDFContextAuthor, nil]);
    //PDF文档是分页的，开启一页文档开始绘制
    UIGraphicsBeginPDFPage();
    //绘制文字
    NSString *content1 = @"WONG! !";
    NSMutableParagraphStyle *style1 = [[NSMutableParagraphStyle alloc]init];
    NSTextAlignment align1 = NSTextAlignmentLeft;
    style1.alignment = align1;
    [content1 drawInRect:CGRectMake(56, 120, 300, 50) withAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"Marker Felt" size:35],NSParagraphStyleAttributeName:style1}];
    NSString *content = @"WONG WONG WONG!!";
    NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc]init];
    NSTextAlignment align = NSTextAlignmentLeft;
    style.alignment = align;
    [content drawInRect:CGRectMake(56, 180, 300, 50) withAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"Marker Felt" size:30],NSParagraphStyleAttributeName:style}];
    //绘制图片
    UIImage *image = [UIImage imageNamed:@"dog_PNG2454.png"];
    [image drawInRect:CGRectMake(200, 390, 233, 400)];
    //关闭PDF图形上下文
    UIGraphicsEndPDFContext();
