根据截止日期对 EKReminder 进行排序

Question

I have an array of EKReminder objects and I would like to sort them by due date.

This seems easy at first, doing something like this:

NSSortDescriptor *dateDescriptor = [NSSortDescriptor sortDescriptorWithKey:@"dueDate" ascending:YES];

[remindersArray sortUsingDescriptors:@[dateDescriptor]];

However the due date of an EKReminder is an NSDateComponents object not an NSDate .

Any ideas?

Answer 1

So, after some research I managed to solve it relatively easy:

[allReminders sortUsingComparator:^NSComparisonResult(id obj1,id obj2){
        EKReminder *reminder1 = obj1;
        EKReminder *reminder2 = obj2;

        NSDate *date1 = [reminder1.dueDateComponents date];
        NSDate *date2 = [reminder2.dueDateComponents date];
        return [date1 compare:date2];
     }];

Hope this helps someone!
