ios - 事件未添加到日历中吗？

我从服务中获取日期和时间，并且我将日期和时间合并为一个，然后将其存储到活动日期中，但未添加到日历中。
到目前为止，我已经结合了日期和时间

-(NSDate *)getDateFromService:(NSString *)str{
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
    //[dateFormatter setDateFormat:@"dd-MM-yyyy"];
    [dateFormatter setDateFormat:@"MM-dd-yyyy"];
    NSDate *dateFromString = [dateFormatter dateFromString:str];
//    return dateFromString;
    NSDate *date = dateFromString;

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

    // Split the date into components but only take the year, month and day and leave the rest behind
    NSDateComponents *dateComponents = [calendar components:(NSYearCalendarUnit | NSMonthCalendarUnit | NSDayCalendarUnit) fromDate:date];

    // Build the date formatter
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"HH:mm:ss"];

    // Convert the string time into an NSDate
    NSDate *time = [formatter dateFromString:timeToBeStore];

    // Split this one in components as well but take the time part this time
    NSDateComponents *timeComponents = [[NSCalendar currentCalendar] components:(NSHourCalendarUnit | NSMinuteCalendarUnit ) fromDate:time];

    // Do some merging between the two date components
    dateComponents.hour = timeComponents.hour;
    dateComponents.minute = timeComponents.minute;

    // Extract the NSDate object again
    NSDate *result = [calendar dateFromComponents:dateComponents];

    // Check if this was what you where looking for
    NSLog(@"%@",result);
    return result;
}

存储到EventKit

-(void)addToCalenderEvent:(NSString *)eventTitle{
    EKEventStore *store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) { return; }
        EKEvent *event = [EKEvent eventWithEventStore:store];
        event.title = eventTitle;
//        NSString *atTime=[NSString stringWithFormat:@"%@T%@",dateToBeStore,timeToBeStore];
        NSDate *date = [self getDateFromService:dateToBeStore];
        event.startDate = date; //today
       // event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
        event.calendar = [store defaultCalendarForNewEvents];
        NSError *err = nil;
        [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
        self.savedEventId = event.eventIdentifier;  //save the event id if you want to access this later
    }];
}

dateToBeStore是我的服务日期值。
timeToBeStore是我的服务时间价值。

我的服务器值
eventDate =“ 12-09-2015”;
eventTime =“ 13:45:00”;

dateToBeStore=[NSString stringWithFormat:@"%@",[response valueForKey:@"eventDate"]];
    timeToBeStore=[NSString stringWithFormat:@"%@",[response valueForKey:@"eventTime"]];

可能是什么原因？此代码有什么问题？
如果我只给个约会，那就可以了。

最佳答案

找到了解决方案
我需要为此设置结束日期

-(void)addToCalenderEvent:(NSString *)eventTitle{
    EKEventStore *store = [EKEventStore new];
    [store requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
        if (!granted) { return; }
        EKEvent *event = [EKEvent eventWithEventStore:store];
        event.title = eventTitle;
//        NSString *atTime=[NSString stringWithFormat:@"%@T%@",dateToBeStore,timeToBeStore];
        NSDate *date = [self getDateFromService:dateToBeStore];
        event.startDate = date; //today
        event.endDate = [event.startDate dateByAddingTimeInterval:60*60];  //set 1 hour meeting
        event.calendar = [store defaultCalendarForNewEvents];
        NSError *err = nil;
        [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
        self.savedEventId = event.eventIdentifier;  //save the event id if you want to access this later
    }];
}
I just uncomment the endDate code,then its working.

问题是：
如果您未设置endDate，则您将遇到此错误
错误域= EKErrorDomain代码= 3“尚未设置结束日期。” UserInfo = 0x1753f660 {NSLocalizedDescription =尚未设置结束日期。}
