Setting fromDate and toDate has no effect

[mrbagels]

Here is my code after initializing MNCaldendarView:

NSDate *todayDate = [NSDate date];
NSDateComponents *dateComponents = [[NSDateComponents alloc] init];
[dateComponents setMonth:+6];
NSDate *afterSixMonths = [[NSCalendar currentCalendar] dateByAddingComponents:dateComponents toDate:todayDate options:0];

self.calendarView.fromDate = [NSDate date];
self.calendarView.toDate = afterSixMonths;

As you can see, I am basically wanting to have the calendar only show the next 6 months instead of the next 4 years.

The calendar view seems to basically be ignoring this.

If I go into the commonInit method in MNCalendarView.m and manually change the code from this:

self.toDate     = [self.fromDate dateByAddingTimeInterval:MN_YEAR * 4];

to:

self.toDate     = [self.fromDate dateByAddingTimeInterval:MN_YEAR * 0.5]; //<-------- Multiplied by 0.5 to get 6 months

I can scroll it up so that it shows the full final 6 month, but then it snaps back into place for the month above it. I am assuming it just isn't recognizing that this is now the new "last month". I also can't find the area where it detects the last month, so I am searching for that still.

Any insight would be great, thanks!

oh I figured it out @kbegeman .. you basically just have to call reload data.. this is my code (using NiceDate):

MNCalendarView *calendarView = [[MNCalendarView alloc] initWithFrame:self.view.bounds];
calendarView.delegate = self;

NiceDate *previousDate = [NiceDate niceDate];
previousDate.year--;
calendarView.fromDate = previousDate.date;

NiceDate *futureDate = [NiceDate niceDate];
futureDate.year++;
calendarView.toDate = futureDate.date;

calendarView.selectedDate = [NSDate date];
[calendarView reloadData];

but i thought it would automatically scroll to the selected date! lol anyone knows how to do that?

-(void)scrollToTodaysMonth {
     NSDateComponents *components_ = [[NSCalendar currentCalendar] components:         NSCalendarUnitMonth fromDate:[NSDate date]];
    NSInteger month = [components_ month]-1;
    [calendar.collectionView scrollToItemAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:month] atScrollPosition:PSTCollectionViewScrollPositionTop animated:YES];
}

I call that function to scroll to todays day, you can modify it to the selected date, etc.

(Also-- watch out, I use a subclassed version of UICollectionView called PSTCollectionView, but you can replace PST with UI just fine)
