The weekday value for Friday in the Gregorian calendar is 6, so add the difference between 6 and today to get the number of days to add. Actually, on Saturday that will give you -1, so you want to subtract from 13 then take modulo 7 */ NSDateComponents *componentsToAdd = [[NSDateComponents alloc] init]; [componentsToAdd setDay: (13 - [weekdayComponents weekday]) % 7]; NSDate *friday = [gregorian dateByAddingComponents:componentsToAdd toDate:today options:0]; /* friday now has the same hour, minute, and second as the original date (today). To normalize to midnight, extract the year, month, and day components and create a new date from those components. */ NSDateComponents *components = [gregorian components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate: friday]; // And to set the time to 20:00 [components setHour:22]; friday = [gregorian dateFromComponents:components]; </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.
