所以我需要获取日历中的当前事件。 I.E - 一个已经开始但还没有结束的事件。我写了一些代码，但它不起作用。 通过调试，我注意到我的 oneDayAgo 变量为 nil，我不明白为什么。 oneWeekFromNow 变量很好。
这是我写的方法:
-(void)getCurrentEvent{
// Get appropriate calendar
[self.store requestAccessToEntityType:EKEntityTypeEvent
completion:^(BOOL granted, NSError *error) {
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day -=1;
NSDate *oneDayAgo = [calendar dateByAddingComponents:oneDayAgoComponents
toDate:[NSDate date]
options:0];
NSDateComponents *oneWeekFromNowComponents = [[NSDateComponents alloc] init];
oneWeekFromNowComponents.week = 1;
NSDate *oneWeekFromNow = [calendar dateByAddingComponents:oneWeekFromNowComponents
toDate:[NSDate date]
options:0];
NSPredicate *predicate = [self.store predicateForEventsWithStartDate:oneDayAgo
endDate:oneWeekFromNow
calendars:nil];
NSMutableArray *currentEvens = [[NSMutableArray alloc]init];
// Fetch all events that match the predicate
[self.store enumerateEventsMatchingPredicate:predicate usingBlock:^(EKEvent *event, BOOL *stop) {
if (([event.startDate compare:[NSDate date]] == NSOrderedDescending) &&
([[NSDate date] compare:event.endDate] == NSOrderedDescending)) {
[currentEvens addObject:event];
}
}];
self.lblEvent.text = [NSString stringWithFormat:@"%@", currentEvens];
[self.view reloadInputViews];
}];
最佳答案
试试这个:
NSDateComponents *oneDayAgoComponents = [[NSDateComponents alloc] init];
oneDayAgoComponents.day = -1;
