    <p>I have gone over previous questions touching upon the subject, but <strong>A4 Sized PDF</strong> is the troublesome part.</p> <p>The code I have written below saves a proper (proportional) PDF file, but its size (area wise) is 4 times of A4-Size. If I halve the height and width, I get an A4 sized PDF but the content overflows into two pages. </p> <p>How do I solve the problem? (fundamentally pertaining to scaling)</p> <pre><code>-(void)savePDFFromWebView:(UIWebView*)webView fileName:(NSString*)_fileName { int height, width, header, sidespace; height = 1754; width = 1240; header = 15; sidespace = 30; // set header and footer spaces UIEdgeInsets pageMargins = UIEdgeInsetsMake(header, sidespace, header, sidespace); webView.viewPrintFormatter.contentInsets = pageMargins; UIPrintPageRenderer *renderer = [[UIPrintPageRenderer alloc] init]; [renderer addPrintFormatter:webView.viewPrintFormatter startingAtPageAtIndex:0]; CGSize pageSize = CGSizeMake(width, height); CGRect printableRect = CGRectMake(pageMargins.left, pageMargins.top, pageSize.width - pageMargins.left - pageMargins.right, pageSize.height - pageMargins.top - pageMargins.bottom); CGRect paperRect = CGRectMake(0, 0, pageSize.width, pageSize.height); [renderer setValue:[NSValue valueWithCGRect:paperRect] forKey:@"paperRect"]; [renderer setValue:[NSValue valueWithCGRect:printableRect] forKey:@"printableRect"]; NSData *pdfData = [self printToPDFWithRender:renderer paperRect:paperRect]; // save PDF file NSString *saveFileName = [NSString stringWithFormat:@"%@%dx%d.pdf", _fileName, (int)pageSize.width, (int)pageSize.height]; NSString *savePath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:saveFileName]; [pdfData writeToFile: savePath atomically: YES]; } - (NSData*) printToPDFWithRenderer:(UIPrintPageRenderer*)renderer paperRect:(CGRect)paperRect { NSMutableData *pdfData = [NSMutableData data]; UIGraphicsBeginPDFContextToData( pdfData, paperRect, nil ); [renderer prepareForDrawingPages: NSMakeRange(0, renderer.numberOfPages)]; CGRect bounds = UIGraphicsGetPDFContextBounds(); for ( int i = 0 ; i &lt; renderer.numberOfPages ; i++ ) { UIGraphicsBeginPDFPage(); [renderer drawPageAtIndex: i inRect: bounds]; } UIGraphicsEndPDFContext(); return pdfData; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
