从UITableView生成PDF，在ios中生成Plist

Question

如何在PList，UITableView中存储数据时生成PDF？

我是ios的新手，也是生成pdf

提前致谢。

编辑：

假设您的plist结构为：

===== 首先，您应该添加框架coreText和quartz core。他们导入并定义一些像这样的宏：

#import <QuartzCore/QuartzCore.h>
#import <CoreText/CoreText.h>

#define LEFT_MARGIN 25
#define RIGHT_MARGIN 25
#define TOP_MARGIN 35
#define BOTTOM_MARGIN 50
#define BOTTOM_FOOTER_MARGIN 32
#define DOC_WIDTH 1004
#define DOC_HEIGHT 768

你可以用这种方式得到plist数据：

NSString *path = [[NSBundle mainBundle] pathForResource:@"recipes" ofType:@"plist"];    

// Load the file content and read the data into arrays
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];

// 修改

tableData = [dict objectForKey:@"RecipeName"];//tabledata is global array
self.textToDraw = [tableData objectAtIndex:0];

// 修改

但是下面的代码可以创建动态pdf：

 -(void) btnDrawPdf
{ 

 //    pageSize = CGSizeMake(612, 792); 

 NSString *fileName = @"DemoNetwrk.pdf"; 
 NSString *fontName = @"Helvetica"; 

// NSString * textToDraw = @“您的数据来自plist”;现在发表评论

//[self generatePdfWithFilePath:pdfFileName];
 [self createPDF:fileName **withContent:self.textToDraw**  forSize:14 forFontName:fontName andColor:[UIColor blackColor]];
}

//多页面pdf和pdf将保存在doc目录库中＆gt;应用程序支持＆gt; iPhoneSimulator＆gt;库＆gt;文档（完美在ios 4.3中）

- (void) createPDF:(NSString *)fileName withContent:(NSString *)content forSize:(int)fontSize forFontName:(NSString *)fontName andColor:(UIColor *)color
{

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *newFilePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:fileName];

CGRect a4Page = CGRectMake(0, 0, DOC_WIDTH, DOC_HEIGHT);

NSDictionary *fileMetaData = [[NSDictionary alloc] init];

if (!UIGraphicsBeginPDFContextToFile(newFilePath, a4Page, fileMetaData )) {
    NSLog(@"error creating PDF context");
    return;
}

BOOL done = NO;
CGContextRef context = UIGraphicsGetCurrentContext();

CFRange currentRange = CFRangeMake(0, 0);

CGContextSetTextDrawingMode (context, kCGTextFill);
CGContextSelectFont (context, [fontName cStringUsingEncoding:NSUTF8StringEncoding], fontSize, kCGEncodingMacRoman);
CGContextSetFillColorWithColor(context, [color CGColor]);
// Initialize an attributed string.
CFMutableAttributedStringRef attrString = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0);
CFAttributedStringReplaceString (attrString, currentRange, (CFStringRef)content);

// Create the framesetter with the attributed string.
CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(attrString);

do {
    UIGraphicsBeginPDFPage();



    CGMutablePathRef path = CGPathCreateMutable();

    CGRect bounds = CGRectMake(LEFT_MARGIN,
                               TOP_MARGIN,
                               DOC_WIDTH - RIGHT_MARGIN - LEFT_MARGIN,
                               DOC_HEIGHT - TOP_MARGIN - BOTTOM_MARGIN);

    CGPathAddRect(path, NULL, bounds);



    // Create the frame and draw it into the graphics context
    CTFrameRef frame = CTFramesetterCreateFrame(framesetter, currentRange, path, NULL);

    if(frame) {
        CGContextSaveGState(context);
        CGContextTranslateCTM(context, 0, bounds.origin.y);
        CGContextScaleCTM(context, 1, -1);
        CGContextTranslateCTM(context, 0, -(bounds.origin.y + bounds.size.height));
        CTFrameDraw(frame, context);
        CGContextRestoreGState(context);

        // Update the current range based on what was drawn.
        currentRange = CTFrameGetVisibleStringRange(frame);
        currentRange.location += currentRange.length;
        currentRange.length = 0;

        CFRelease(frame);
    }

     // If we're at the end of the text, exit the loop.
    if (currentRange.location == CFAttributedStringGetLength((CFAttributedStringRef)attrString))
        done = YES;
}
while(!done);

UIGraphicsEndPDFContext();

//    [fileMetaData release];  
 CFRelease(attrString);  
 CFRelease(framesetter);

}

This可能就是你要找的东西。

您应该在将Plist转换为PDF之前将其呈现为屏幕（加载数据并将其显示在UIView或继承自UIView的类中。
