    <p>I have a string like this 13, 27, 29 representing days of the month I want to separate them like below into date objects</p> <pre><code>mayString = [mayString componentsSeparatedByString:@","]; </code></pre> <p>I then want to be able to work out which of these days i.e 13 or 27 or 29 is closest to todays date which obviously taking the above dates would be 27 as the next closest date to current date.</p> <p>I can grab current day using the below but really stuck on how to get the logic to do this?</p> <pre><code>//Grab current day from sys date NSDateFormatter *dayFormatter = [[NSDateFormatter alloc] init]; [dayFormatter setDateFormat:@"dd"]; NSString *dayString = [dayFormatter stringFromDate:[NSDate date]]; </code></pre> <p>I have a partial completed solution but it doesnt seem to give me the correct result of what index in the array is closest to current day (sepDates is an array)</p> <pre><code>sepDates = [mayString componentsSeparatedByString:@","]; //Day string is todays date i.e 16 (16th) NSDate *dayFromString = [dayFormatter dateFromString:dayString]; NSLog(@"Day from string %@", dayFromString); double min = [dayFromString timeIntervalSinceDate:[sepDates objectAtIndex:0]]; NSLog(@"Min %f", min); //I then want to calculate which of the dates in the sepDates array at index is closest to todays current day 16 int minIndex = 0; for (int d = 1; d &lt; [sepDates count]; ++d) { double currentmin = [dayFromString timeIntervalSinceDate:[sepDates objectAtIndex:d]]; if (currentmin &lt; min) { min = currentmin; minIndex = d; NSLog(@"minIndex = %d", minIndex); } } </code></pre>

    1. COCan you check that your `dayString` object is correctly formatted by logging its value? `NSDateFormatter` does weird stuff sometimes.

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.
