Question

im trying to create an event from my app, to add it to the calendar, im using the code below:
- (IBAction)refreshTapped:(id)sender {
// [self performSegueWithIdentifier:#"calendarsegue" sender:nil];
EKEventStore *store = [[EKEventStore alloc] init];
if([store respondsToSelector:#selector(requestAccessToEntityType:completion:)])
{
// iOS 6
[store requestAccessToEntityType:EKEntityTypeEvent
completion:^(BOOL granted, NSError *error) {
if (granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
[self createEventAndPresentViewController:store];
});
}
}];
} else
{
// iOS 5
[self createEventAndPresentViewController:store];
}
}
- (void)createEventAndPresentViewController:(EKEventStore *)store
{
EKEvent *event = [self findOrCreateEvent:store];
EKEventEditViewController *controller = [[EKEventEditViewController alloc] init];
controller.event = event;
controller.eventStore = store;
controller.editViewDelegate = self;
[self presentViewController:controller animated:YES completion:nil];
}
- (EKEvent *)findOrCreateEvent:(EKEventStore *)store
{
NSString *title = #"My event title";
// try to find an event
EKEvent *event = [self findEventWithTitle:title inEventStore:store];
// if found, use it
if (event)
return event;
// if not, let's create new event
event = [EKEvent eventWithEventStore:store];
event.title = title;
event.notes = #"";
// event.location = #"Lebanon";
event.calendar = [store defaultCalendarForNewEvents];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [[NSDateComponents alloc] init];
components.hour = 4;
event.startDate = [calendar dateByAddingComponents:components
toDate:[NSDate date]
options:0];
components.hour = 1;
event.endDate = [calendar dateByAddingComponents:components
toDate:event.startDate
options:0];
return event;
}
- (EKEvent *)findEventWithTitle:(NSString *)title inEventStore:(EKEventStore *)store
{
// Get the appropriate calendar
NSCalendar *calendar = [NSCalendar currentCalendar];
// Create the start range date components
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day = -1;
NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents
toDate:[NSDate date]
options:0];
// Create the end range date components
NSDateComponents *oneWeekFromNowComponents = [[NSDateComponents alloc] init];
oneWeekFromNowComponents.day = 7;
NSDate *oneWeekFromNow = [calendar dateByAddingComponents:oneWeekFromNowComponents
toDate:[NSDate date]
options:0];
// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:oneDayAgo
endDate:oneWeekFromNow
calendars:nil];
// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];
for (EKEvent *event in events)
{
if ([title isEqualToString:event.title])
{
return event;
}
}
return nil;
}
- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action
{
[self dismissViewControllerAnimated:YES completion:nil];
// [self fetchCalendarEvents];
}
the event page is opening normally, but when i want to enter the location by keyboard, the app is crashing and giving me the error above in the title enter image description here
Anyone knows where the error is?thanks
