    <p>in my app I'm displaying a list of EKEvents and I would like to display all events of a month in a UITableView, each section containing the respective days. Well, this works and I get all the data, I need, but the fetch is very slow.</p> <p>The problem consists in events, which spread across multiple days.</p> <ul> <li>Let's say I'm going on vacation from 10th of November until 17th of November.</li> <li>My search predicate has a startDate with 1st of November and an endDate with 30th of November.</li> <li>I do an enumerateEventsMatchingPredicate or eventsMatchingPredicate, whatever, both are slow.</li> </ul> <p>I get an array in return with all events taking place in November, as well as my vacation. But my vacation is just one EKEvent object. So if I want to display a monthly list view of events it would only appear once, on 10th of November, but for reasons of clarity I would to show it on every day it takes place, 10th, 11th, ... 17th.</p> <p>So what I do is, iterate over each day in a month and do a fetch :-/ This way I get the correct amount of events that take place on a specific day, but ... it feels so complicated.</p> <p>I already put the fetch into a dispatch_async, so the fetch doesn't block the UI and after the fetch is finished the tableView gets reloaded and cells redrawn. But it still takes time. No userfriendly time.</p> <p>How do you perform those searches? Do you have any tips on how to speed up the search, maybe a little code snippet or can point me in the right direction!?</p> <p>Is my question clear? :-/</p> <p>Thanks, -Martin.</p>

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.
