    <p>I have the following code:</p> <pre><code>NSString *name = @"some text goes in here"; CFStringRef string = (__bridge CFStringRef) self.highlightItem_.comment; CFMutableAttributedStringRef comment = CFAttributedStringCreateMutable(kCFAllocatorDefault, 0); CFAttributedStringReplaceString (comment ,CFRangeMake(0, 0), string); CGColorRef blue =[UIColor colorWithRed:128/255.f green:203/255.f blue:255/255.f alpha:1.0].CGColor; CGColorRef gray =[UIColor colorWithWhite:153/255.f alpha:1.0].CGColor; CFAttributedStringSetAttribute(comment, CFRangeMake(0, [name length]),kCTForegroundColorAttributeName, blue); CFAttributedStringSetAttribute(comment, CFRangeMake([name length], [self.highlightItem_.comment length] - [name length]),kCTForegroundColorAttributeName, gray); CTFontRef nameFont = CTFontCreateWithName((__bridge CFStringRef)kProximaNovaBold, 15.0f, nil); CFAttributedStringSetAttribute(comment,CFRangeMake(0, [name length]),kCTFontAttributeName,nameFont); CTFontRef commentFont = CTFontCreateWithName((__bridge CFStringRef)kProximaNova, 15.0f, nil); CFAttributedStringSetAttribute(comment, CFRangeMake([name length], [self.highlightItem_.comment length] - [name length]),kCTFontAttributeName,commentFont); CGContextSaveGState(context); CGRect captionFrame = CGRectMake(0, 0, rect.size.width - 80, commentHeight); CTFramesetterRef framesetter = CTFramesetterCreateWithAttributedString(comment); CGMutablePathRef captionFramePath = CGPathCreateMutable(); CGPathAddRect(captionFramePath, NULL, captionFrame); CTFrameRef mainCaptionFrame = CTFramesetterCreateFrame(framesetter, CFRangeMake(0, 0), captionFramePath, NULL); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetTextMatrix(context, CGAffineTransformIdentity); CGContextTranslateCTM(context, 70, self.imageHeight_ + commentHeight + 20); CGContextScaleCTM(context, 1.0, -1.0); CTFrameDraw(mainCaptionFrame, context); CGContextRestoreGState(context); CFRelease(framesetter); CGPathRelease(captionFramePath); </code></pre> <p>I am not sure why when I run it on the simulator it all worked fine, but when I run it on the device, it crashes on this line:</p> <pre><code>CFAttributedStringSetAttribute(comment, CFRangeMake(0, [name length]),kCTForegroundColorAttributeName, blue); </code></pre> <p>any idea why?</p>

    1. COI deleted my answer, I didn't see that you was already taking the CGColor attribute from UIColor.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
