How can I retrieve all events from an iPhone calendar?

I want to know how to read all events in an iPhone calendar in a programmatic way?

I know the way by which we can retrieve events of known days. The following code retrieves the开发者_运维百科 events for the current date. But how can I retrieve all saved events in an iPhone calendar ie. not depending on dates?

NSDate *startDate = [NSDate date];

// endDate is 1 day = 60*60*24 seconds = 86400 seconds from startDate
NSDate *endDate = [NSDate dateWithTimeIntervalSinceNow:(86400*1)];

// Create the predicate. Pass it the default calendar.
NSArray *calendarArray = [NSArray arrayWithObject:defaultCalendar];
NSPredicate *predicate = [self.eventStore predicateForEventsWithStartDate:startDate endDate:endDate calendars:calendarArray]; 

// Fetch all events that match the predicate.
NSArray *events = [self.eventStore eventsMatchingPredicateredicate];

You can fetch events from a user’s Calendar database using three ways : 1)Fetching Events as a Event Store 2)Fetching Events with a Predicate 3)Fetching Individual Events with an Identifier

You can use either Predicate or Identifier, follow the IOS guidelines to see some examles and details.

hopes this Helps.
