    <p><strong>Brief Description</strong></p> <ol> <li><p>Just another approach to complete the answer of JBRWilkinson but adding some code. It can also offers a solution to Alex Reynolds's comment. </p></li> <li><p>Use NSCalendar method:</p> <ul> <li><p><code>(NSDateComponents *)components:(NSUInteger)unitFlags fromDate:(NSDate *)startingDate toDate:(NSDate *)resultDate options:(NSUInteger)opts</code></p></li> <li><p>"Returns, as an NSDateComponents object using specified components, the difference between two supplied dates". (From the API documentation). </p></li> </ul></li> <li><p>Create 2 NSDate whose difference is the NSTimeInterval you want to break down. (If your NSTimeInterval comes from comparing 2 NSDate you don't need to do this step, and you don't even need the NSTimeInterval, just apply the dates to the NSCalendar method).</p></li> <li><p>Get your quotes from NSDateComponents</p></li> </ol> <p><strong>Sample Code</strong></p> <pre><code>// The time interval NSTimeInterval theTimeInterval = ...; // Get the system calendar NSCalendar *sysCalendar = [NSCalendar currentCalendar]; // Create the NSDates NSDate *date1 = [[NSDate alloc] init]; NSDate *date2 = [[NSDate alloc] initWithTimeInterval:theTimeInterval sinceDate:date1]; // Get conversion to months, days, hours, minutes NSCalendarUnit unitFlags = NSHourCalendarUnit | NSMinuteCalendarUnit | NSDayCalendarUnit | NSMonthCalendarUnit; NSDateComponents *breakdownInfo = [sysCalendar components:unitFlags fromDate:date1 toDate:date2 options:0]; NSLog(@"Break down: %i min : %i hours : %i days : %i months", [breakdownInfo minute], [breakdownInfo hour], [breakdownInfo day], [breakdownInfo month]); </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.

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).
