EKEvent is not added according to given EKRecurrenceRule

EKEvent is not added according to given EKRecurrenceRule

I'm trying to add an event into calendar with recurrence rule
RRULE:FREQ=YEARLY;BYMONTH=6,7;BYDAY=1TH
So according to this rule the event should be added yearly, each 1st
thursday of june and july until expire date, which I've set in my project.
In my project, events are created but not according to the recurrence rule.
Here is .m file code
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[self createEvent];
}
- (void)createEvent
{
EKEventStore *eventStore = [[EKEventStore alloc] init];
EKEvent *event = [EKEvent eventWithEventStore:eventStore];
event.title = @"testRecurrenceRule";
event.location = @"Dhaka";
[event setCalendar:[eventStore defaultCalendarForNewEvents]];
event.startDate = [self dateFromString:@"2013-06-18T21:00:00+06:00"];
event.endDate = [self dateFromString:@"2013-06-18T22:00:00+06:00"];
id recurrenceRule = [self recurrenceRuleForEvent];
if(recurrenceRule != nil)
[event addRecurrenceRule:recurrenceRule];
if ([eventStore
respondsToSelector:@selector(requestAccessToEntityType:completion:)])
{
// iOS 6 and later
[eventStore requestAccessToEntityType:EKEntityTypeEvent
completion:^(BOOL granted, NSError *error) {
if (granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
[self saveTheEvent:event eventStore:eventStore];
//[eventStore saveEvent:event span:EKSpanThisEvent
error:error];
});
}
else
{
dispatch_async(dispatch_get_main_queue(), ^{
//do nothing
});
}
}];
}
else
{
[self saveTheEvent:event eventStore:eventStore];
}
textView.text = [NSString stringWithFormat:@"Event has been added with
recurrence rule %@",recurrenceRule];
}
- (void)saveTheEvent:(EKEvent *)aEvent eventStore:(EKEventStore *)aStore
{
[aStore saveEvent:aEvent span:EKSpanThisEvent error:NULL];
}
- (EKRecurrenceRule *)recurrenceRuleForEvent
{
//just creating a recurrence rule for
RRULE:FREQ=YEARLY;BYMONTH=6,7;BYDAY=1TH
// setting the values directly for testing purpose.
//FREQ=YEARLY
EKRecurrenceFrequency recurrenceFrequency = EKRecurrenceFrequencyYearly;
NSInteger recurrenceInterval = 1;

that extra ':', just replacing it here.

Can somebody please help me regarding this?
