    <p>I used as sample <a href="https://github.com/Tuszy/MTLabel" rel="nofollow">MTLabel</a>. It allows to manage line height. I needed the draw method exactly, so i just put away most stuff i did not need. This method allows me to draw multilined text in rect with tail truncation.</p> <pre><code>CGRect CTLineGetTypographicBoundsAsRect(CTLineRef line, CGPoint lineOrigin) { CGFloat ascent = 0; CGFloat descent = 0; CGFloat leading = 0; CGFloat width = CTLineGetTypographicBounds(line, &amp;ascent, &amp;descent, &amp;leading); CGFloat height = ascent + descent; return CGRectMake(lineOrigin.x, lineOrigin.y - descent, width, height); } - (void)drawText:(NSString*) text InRect:(CGRect)rect withFont:(UIFont*)aFont inContext:(CGContextRef)context { if (!text) { return; } BOOL _limitToNumberOfLines = YES; int _numberOfLines = 2; float _lineHeight = 22; //Create a CoreText font object with name and size from the UIKit one CTFontRef font = CTFontCreateWithName((CFStringRef)aFont.fontName , aFont.pointSize, NULL); //Setup the attributes dictionary with font and color NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys: (id)font, (id)kCTFontAttributeName, [UIColor lightGrayColor].CGColor, kCTForegroundColorAttributeName, nil]; NSAttributedString *attributedString = [[[NSAttributedString alloc] initWithString:text attributes:attributes] autorelease]; CFRelease(font); //Create a TypeSetter object with the attributed text created earlier on CTTypesetterRef typeSetter = CTTypesetterCreateWithAttributedString((CFAttributedStringRef)attributedString); //Start drawing from the upper side of view (the context is flipped, so we need to grab the height to do so) CGFloat y = self.bounds.origin.y + self.bounds.size.height - rect.origin.y - aFont.ascender; BOOL shouldDrawAlong = YES; int count = 0; CFIndex currentIndex = 0; float _textHeight = 0; CGContextSaveGState(context); CGContextSetTextMatrix(context, CGAffineTransformIdentity); CGContextTranslateCTM(context, 0, self.bounds.size.height); CGContextScaleCTM(context, 1.0, -1.0); //Start drawing lines until we run out of text while (shouldDrawAlong) { //Get CoreText to suggest a proper place to place the line break CFIndex lineLength = CTTypesetterSuggestLineBreak(typeSetter, currentIndex, rect.size.width); //Create a new line with from current index to line-break index CFRange lineRange = CFRangeMake(currentIndex, lineLength); CTLineRef line = CTTypesetterCreateLine(typeSetter, lineRange); //Check to see if our index didn't exceed the text, and if should limit to number of lines if (currentIndex + lineLength &gt;= [text length]) { shouldDrawAlong = NO; } else { if (!(_limitToNumberOfLines &amp;&amp; count &lt; _numberOfLines-1)) { int i = 0; if ([[[text substringWithRange:NSMakeRange(currentIndex, lineLength)] stringByAppendingString:@"…"] sizeWithFont:aFont].width &gt; rect.size.width) { i--; while ([[[text substringWithRange:NSMakeRange(currentIndex, lineLength + i)] stringByAppendingString:@"…"] sizeWithFont:aFont].width &gt; rect.size.width) { i--; } } else { i++; while ([[[text substringWithRange:NSMakeRange(currentIndex, lineLength + i)] stringByAppendingString:@"…"] sizeWithFont:aFont].width &lt; rect.size.width) { i++; } i--; } attributedString = [[[NSAttributedString alloc] initWithString:[[text substringWithRange:NSMakeRange(currentIndex, lineLength + i)] stringByAppendingString:@"…"] attributes:attributes] autorelease]; CFRelease(typeSetter); typeSetter = CTTypesetterCreateWithAttributedString((CFAttributedStringRef)attributedString); CFRelease(line); CFRange lineRange = CFRangeMake(0, 0); line = CTTypesetterCreateLine(typeSetter, lineRange); shouldDrawAlong = NO; } } CGFloat x = rect.origin.x; //Setup the line position CGContextSetTextPosition(context, x, y); CTLineDraw(line, context); count++; CFRelease(line); y -= _lineHeight; currentIndex += lineLength; _textHeight += _lineHeight; } CFRelease(typeSetter); CGContextRestoreGState(context); } </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.
