    <p>You should add your run delegate as an attribute for a range of characters in your attributed string. See <a href="http://developer.apple.com/iphone/library/documentation/Carbon/Reference/CoreText_StringAttributes_Ref/Reference/reference.html#//apple_ref/doc/c_ref/kCTRunDelegateAttributeName" rel="noreferrer">Core Text String Attributes</a>. When drawing, Core Text will call your callbacks to get the sizing of that characters.</p> <p><strong>Update</strong></p> <p>This is a sample code for a view drawing a simple text (Note that there's no memory management code here).</p> <pre><code>@implementation View /* Callbacks */ void MyDeallocationCallback( void* refCon ){ } CGFloat MyGetAscentCallback( void *refCon ){ return 10.0; } CGFloat MyGetDescentCallback( void *refCon ){ return 4.0; } CGFloat MyGetWidthCallback( void* refCon ){ return 125; } - (void)drawRect:(CGRect)rect { // create an attributed string NSMutableAttributedString * attrString = [[NSMutableAttributedString alloc] initWithString:@"This is my delegate space"]; // create the delegate CTRunDelegateCallbacks callbacks; callbacks.version = kCTRunDelegateVersion1; callbacks.dealloc = MyDeallocationCallback; callbacks.getAscent = MyGetAscentCallback; callbacks.getDescent = MyGetDescentCallback; callbacks.getWidth = MyGetWidthCallback; CTRunDelegateRef delegate = CTRunDelegateCreate(&amp;callbacks, NULL); // set the delegate as an attribute CFAttributedStringSetAttribute((CFMutableAttributedStringRef)attrString, CFRangeMake(19, 1), kCTRunDelegateAttributeName, delegate); // create a frame and draw the text CTFramesetterRef frameSetter = CTFramesetterCreateWithAttributedString((CFAttributedStringRef)attrString); CGMutablePathRef path = CGPathCreateMutable(); CGPathAddRect(path, NULL, rect); CTFrameRef frame = CTFramesetterCreateFrame(frameSetter, CFRangeMake(0, attrString.length), path, NULL); CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetTextMatrix(context, CGAffineTransformIdentity); CGContextSetTextPosition(context, 0.0, 0.0); CTFrameDraw(frame, context); } @end </code></pre> <p>The size of the space character between "delegate" and "space" in the text are controlled by the run delegate.</p>

    1. COI already did that but it is not helping. The documentation itself doesn't give much info about CTRunDelegate. if you have any sample code for CTRunDelegate , that will be of great help.

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.

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