    <p>I'm not sure if all the code you posted is from the same version, but if you threw that together I'd see at least the following problem:</p> <p>You say</p> <pre><code>[event setCalendar:calendararray]; </code></pre> <p>doesn't work.</p> <p>It seems <code>calendararray</code> ist set in <code>eventview.m</code>'s <code>calendararray:</code> method.</p> <p>This in turn is called from <code>calendar.m</code>'s <code>pickerView:didSelectRow:</code>, where it takes the selected object from <code>arrayColors</code>.</p> <p>In <code>calendar.m</code>'s <code>viewDidLoad</code> method, <code>arrayColors</code> is initialised with the users's calendars' titles, not the calendars. So you end up giving <code>EKEvent</code>'s <code>setCalendar:</code> method an <code>NSString</code> instead of an <code>EKCalendar</code>.</p> <p>Not knowing the rest of your program, as a fix I would try to keep the <code>EKCalendar</code> objects themselves in <code>arrayColors</code>.</p> <p>So, in <code>calendar.m</code> try to change the</p> <pre><code> [arrayColors addObject:thisCalendar.title]; </code></pre> <p>in <code>viewDidLoad</code> to</p> <pre><code> [arrayColors addObject:thisCalendar]; </code></pre> <p>Then change <code>pickerView:titleForRow:</code> to</p> <pre><code>- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { EKEvent *event = [arrayColors objectAtIndex:row] return event.title; } </code></pre> <p>FInally, in <code>eventview.m</code> change <code>calendararray:</code></p> <pre><code>- (void) calendararray:(EKCalendar *)array{ NSLog(@"calendarNameTextFieldStringFromTable %@", array); calendararray = array; calendarLabel.text = array.title; calendarLabel.textColor = [UIColor brownColor]; } </code></pre>

    2. CO* please don't edit your question to be a completely different one (i.e. "how do I find all the user's calendars?" vs. "setting a a specific calendar for an event does not work for me"); open a new question instead; otherwise the answers people gave for the first version of the question will seem nonsensical for new readers who will only see the latest version of the question

    3. CO* the calendararray: method looks suspicious regarding memory management; the array should probably be retained (take a look at the [Memory Management Programming Guide](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/MemoryMgmt.html), especially the part on [Accessor Methods](http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmAccessorMethods.html]).

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).
