试试这个

// Get the appropriate calendar
NSCalendar *calendar = [NSCalendar currentCalendar];

// Create the start date components
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day = -1;
NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents
                                              toDate:[NSDate date]
                                             options:0];

// Create the end date components
NSDateComponents *oneYearFromNowComponents = [[NSDateComponents alloc] init];
oneYearFromNowComponents.year = 1;
NSDate *oneYearFromNow = [calendar dateByAddingComponents:oneYearFromNowComponents
                                                   toDate:[NSDate date]
                                                  options:0];

// Create the predicate from the event store's instance method
NSPredicate *predicate = [store predicateForEventsWithStartDate:oneDayAgo
                                                        endDate:oneYearFromNow
                                                      calendars:nil];

// Fetch all events that match the predicate
NSArray *events = [store eventsMatchingPredicate:predicate];
