Question

我在我的应用程序中添加了以下代码。如果[comps setYear：1]它正常工作但是如果我将年份值更改为2或大于2代码不会显示任何错误但也不会在日历中添加任何事件。这仅在iOS 7中发生。但如果我在iOS 6上运行相同的代码，它的工作正常＆amp;事件成功添加到日历中。 iOS 7中是否有限制添加未来事件？

-(void)addEvent{
    EKEventStore *es = [[EKEventStore alloc] init];
    EKAuthorizationStatus authorizationStatus = [EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent];
    BOOL needsToRequestAccessToEventStore = (authorizationStatus == EKAuthorizationStatusNotDetermined);

    if (needsToRequestAccessToEventStore) {
        [es requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            if (granted) {
                [self setEventForStore:es];
            } else {

            }
        }];
    } else {
        BOOL granted = (authorizationStatus == EKAuthorizationStatusAuthorized);
        if (granted) {
            [self setEventForStore:es];


        } else {

        }
    }
}

-(void)setEventForStore:(EKEventStore*)store{
    EKEvent *event = [EKEvent eventWithEventStore:store];
    event.title = @"Event 4";

    NSCalendar *calendar = [NSCalendar currentCalendar];
    NSDateComponents *comps = [NSDateComponents new];
    // comps.day =3650;
    comps.day=5;
    comps.hour=1;
    comps.year=2;
    NSDate *sevenDays = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];
    event.startDate = sevenDays;

    NSDate *sevenDays1 = [event.startDate dateByAddingTimeInterval:60*60];;
    // duration = 1 h
    event.endDate = sevenDays1;

    [event setCalendar:[store defaultCalendarForNewEvents]];
    NSError *err = nil;
    [store saveEvent:event span:EKSpanThisEvent commit:YES error:&err];
}

每当通过组件处理日期时，请按以下方式设置：

NSDateComponents *comps = [[[NSDateComponents alloc] init] autorelease];
[comps setDay:05];
[comps setMonth:01];
[comps setYear:2014]; //instead of adding a single digit number like so: 2

//followed by your code...
NSDate *sevenDays = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];
//...

您提到在稍微调整NSDate组件中的整数值时，您的事件未保存在日历中。通过NSLogging您的约会，可以快速了解最新情况。在尝试将其添加到日历之前，请查看输出的内容。

//Right after this below line
NSDate *sevenDays = [calendar dateByAddingComponents:comps toDate:[NSDate date] options:0];

//Add the code here so we can see what `sevenDays` prints out.
    NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSString *strDate = [dateFormatter stringFromDate:sevenDays];
NSLog(@"Seven Days date = %@", strDate);

EventKit saveEvent在iOS 7中不起作用
