I am trying to create an event and store it in the default calendar using this common piece of code:
EKEventStore *eventDB = [[EKEventStore alloc] init];
EKEvent *myEvent = [EKEvent eventWithEventStore:eventDB];
myEvent.title = titolo;
myEvent.startDate = [NSDate date];
myEvent.calendar = [eventDB defaultCalendarForNewEvents];
myEvent.endDate = data;
myEvent.allDay = NO;
myEvent.notes = note;
NSMutableArray *myAlarmsArray = [[NSMutableArray alloc] init];
EKAlarm *alarm1 = [EKAlarm alarmWithRelativeOffset:-300]; // 5 minutes
EKAlarm *alarm2 = [EKAlarm alarmWithRelativeOffset:-3600]; // 1 hour
EKAlarm *alarm3 = [EKAlarm alarmWithRelativeOffset:-86400]; // 1 day
[myAlarmsArray addObject:alarm1];
[myAlarmsArray addObject:alarm2];
[myAlarmsArray addObject:alarm3];
myEvent.alarms = myAlarmsArray;
[myAlarmsArray release];
NSError *err;
[eventDB saveEvent:myEvent span:EKSpanThisEvent error:&err];
if (err == noErr) {
return YES;
} else {
[Utils logError:err];
return NO;
}
It gives not a single problem in the simulator, but when running it on the physical device this will hang on indefinitely when I call [eventDB saveEvent:span:error:]. I tested in the simulator with iOS 4.2/4.3 and iOS 5.0.1, and on the real device I have iOS 5.0.1 installed.
What am I doing wrong here? Is it my fault or did I misconfigured the app somewhere?
Thank you.
Update
Here is the stack trace of the call when I pause the app via Xcode:

At step #17 there is the call that hangs.
This appears to be caused by a bug in iOS 5, and the app crashes when setting more than one alarm on an event. Everything works fine when using a single alarm.
I did not try this on iOS 6, so I cannot tell you if Apple solved the problem.
