How to create PDF document using iPhone SDK? [duplicate]

Answer 1

Theres a great open source api for creating PDFs. You can add text, images, and headers to the PDF, and then either send the PDF or save it to a file. The Api is at http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI If you have any questions about it, the support is great, just contact maor.kern@mobice.org

Answer 3

You can use UIKit to generate a pdf. Its really simple. You just have to start a pdf context and write out contents to it:

    NSString *fileName = @"Demo.pdf";
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];

    [self generatePdfWithFilePath:pdfFileName];
}
- (void) generatePdfWithFilePath: (NSString *)thefilePath

    UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);

    NSInteger currentPage = 0;
    BOOL done = NO;
    do
    {
        // Mark the beginning of a new page.
        UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, pageSize.width, pageSize.height), nil);

        // Draw a page number at the bottom of each page.
        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];
