判断是否可以访问日历

EKEventStore *store = [[EKEventStore alloc] init];    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {        if (granted == YES) {            NSLog(@"同意");        }else{            NSLog(@"不同意");        }    }];

获取日历事件

// 获取适当的日期（Get the appropriate calendar）    NSCalendar *calendar = [NSCalendar currentCalendar];        // 创建起始日期组件（Create the start date components）    NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];    oneDayAgoComponents.day = -1;    NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents                                                  toDate:[NSDate date]                                                 options:0];        // 创建结束日期组件（Create the end date components）    NSDateComponents *oneYearFromNowComponents = [[NSDateComponents alloc] init];    oneYearFromNowComponents.year = 1;    NSDate *oneYearFromNow = [calendar dateByAddingComponents:oneYearFromNowComponents                                                       toDate:[NSDate date]                                                      options:0];        // 用事件库的实例方法创建谓词 (Create the predicate from the event store's instance method)    NSPredicate *predicate = [store predicateForEventsWithStartDate:oneDayAgo                                                            endDate:oneYearFromNow                                                          calendars:nil];        // 获取所有匹配该谓词的事件(Fetch all events that match the predicate)    NSArray *events = [store eventsMatchingPredicate:predicate];    for (EKEvent *e in events) {        NSLog(@"%@",e.title);        NSLog(@"%@",e.startDate);        NSLog(@"%@",e.endDate);        NSLog(@"-------------------------");    }

添加一个日历事件

 // Get the event store object    self.eventStore = [[EKEventStore alloc] init];        // Create a new event    EKEvent *event  = [EKEvent eventWithEventStore:self.eventStore];        // Create NSDates to hold the start and end date    NSDate *startDate = [[NSDate alloc] init];    NSDate *endDate  = [[NSDate alloc] init];        // Set properties of the new event object    event.title     = @"这是测试";    event.startDate =  [NSDate dateWithTimeIntervalSinceNow:-60*60];    event.endDate   =  [NSDate dateWithTimeIntervalSinceNow:-30];    event.allDay = NO;        // set event's calendar to the default calendar    [event setCalendar:[self.eventStore defaultCalendarForNewEvents]];        // Create an NSError pointer    NSError *err;    // Save the event    [self.eventStore saveEvent:event span:EKSpanThisEvent error:&err];        self.idf = [NSString stringWithFormat:@"%@",event.eventIdentifier];    NSLog(@"%@",event.eventIdentifier);        // Test for errors    if (err == noErr) {        UIAlertView *alert = [[UIAlertView alloc]                              initWithTitle:@"Event Created"                              message:@"How about that?"                              delegate:nil                              cancelButtonTitle:@"Okay"                              otherButtonTitles:nil];        [alert show];              }

删除一个日历事件

EKEvent *eventToRemove = [self.eventStore eventWithIdentifier:self.idf];        if ([eventToRemove.eventIdentifier length] > 0) {        NSError* error = nil;        [self.eventStore removeEvent:eventToRemove span:EKSpanThisEvent error:&error];        if (error) {            NSLog(@"%@",error);        }else {            NSLog(@"ok");        }    }

修改一个日历事件

EKEvent *eventToRemove = [self.eventStore eventWithIdentifier:self.idf];    eventToRemove.title = @"已经修改";    // Save the event    [self.eventStore saveEvent:eventToRemove span:EKSpanThisEvent error:nil];
