    <p>The question is already answered... but I wanted to show how to add shadow and change the font with NSAttributedString as well, so that when people search for this topic they won't have to keep looking.</p> <pre><code>#define FONT_SIZE 20 #define FONT_HELVETICA @"Helvetica-Light" #define BLACK_SHADOW [UIColor colorWithRed:40.0f/255.0f green:40.0f/255.0f blue:40.0f/255.0f alpha:0.4f] NSString*myNSString = @"This is my string.\nIt goes to a second line."; NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init]; paragraphStyle.alignment = NSTextAlignmentCenter; paragraphStyle.lineSpacing = FONT_SIZE/2; UIFont * labelFont = [UIFont fontWithName:FONT_HELVETICA size:FONT_SIZE]; UIColor * labelColor = [UIColor colorWithWhite:1 alpha:1]; NSShadow *shadow = [[NSShadow alloc] init]; [shadow setShadowColor : BLACK_SHADOW]; [shadow setShadowOffset : CGSizeMake (1.0, 1.0)]; [shadow setShadowBlurRadius : 1]; NSAttributedString *labelText = [[NSAttributedString alloc] initWithString : myNSString attributes : @{ NSParagraphStyleAttributeName : paragraphStyle, NSKernAttributeName : @2.0, NSFontAttributeName : labelFont, NSForegroundColorAttributeName : labelColor, NSShadowAttributeName : shadow }]; </code></pre> <p>Here is a Swift version...</p> <p>Warning!

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.

SQuiL has stopped working due to an internal error.
