EKEventStore：事件不会仅从开始日期在设备日历中添加

Question

My String Date是08-17-2016 10:30。我通过此代码将其转换为日期

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MM-dd-yyyy HH:mm"];    
NSDate *dateFromString= [dateFormatter dateFromString:eventDate];
NSLog(@"Date :%@",dateFromString);

我的nslog为 2016-08-17 05:00:00 +0000 。但我的时间是10:30。 我不想给结束日期，因为我希望它在那里直到用户删除它。

- (void)addEventinCalendar:(NSString *)eventTitle andEventDate:(NSString  *)eventDate
{

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"MM-dd-yyyy HH:mm"];

NSDate *dateFromString;
dateFromString = [dateFormatter dateFromString:eventDate];
NSLog(@"Date :%@",dateFromString);
//Date :2016-08-17 05:00:00 +0000

EKEventStore *eventStore = [[EKEventStore alloc] init];    
EKEvent *event = [EKEvent eventWithEventStore:eventStore];

event.title = eventTitle;    
event.startDate = dateFromString;         
[event setCalendar:[eventStore defaultCalendarForNewEvents]];    
NSError *err;
[eventStore saveEvent:event span:EKSpanThisEvent error:&err];

}

实际上您的日期是GMT格式，时间是-5.30小时，所以我们需要添加本地时区并检查

NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd HH:mm"]; // set date format as per your String
NSDate *dateFromString= [dateFormatter dateFromString:@"2016-08-17 10:30"];
NSTimeInterval timeZoneSeconds = [[NSTimeZone localTimeZone] secondsFromGMT];
NSDate *dateInLocalTimezone = [dateFromString dateByAddingTimeInterval:timeZoneSeconds];
NSLog(@"Date :%@",dateInLocalTimezone);

试试这个

 EKEventStore *store = [[EKEventStore alloc] init];
[store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
  if (!granted) return;
  EKEvent *event = [EKEvent eventWithEventStore:store];
  event.title = @"Imran Verified";
  event.startDate = [NSDate date]; // today
  event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  // Duration 1 hr
  [event setCalendar:[store defaultCalendarForNewEvents]];
  NSError *err = nil;
  [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
  NSString *savedEventId = event.eventIdentifier;  // Store this so you can access this event later
}];
