A fully customizable calendar view acting as a date range picker

I'am using GLCalendarView with Xcode 7 and Swift 2. Everything seems to be working fine, except the labels for the months that is supposed to show up when you scroll.

I have set the monthCoverAttributes in the AppDelegate.

GLCalendarView.appearance().monthCoverAttributes = [NSFontAttributeName: UIFont(name: "Lato-Semibold", size: 19)!, NSForegroundColorAttributeName: UIColor.blackColor()]

(Doesn't work even when i don't set the monthCoverAttributes)

Anyone facing same issue? Am I doing something wrong?

Print day and month labels according to locale, respect the users first week day and expose the view's calendar to make it configurable from the outside.

Hello, i have trouble with your view. When i set 10 ranges and set begin date to current date, constraints break.

Please, help me as soon as possible. I have to complete this screen yesterday.

Console:

Code to create:

- (void)viewDidLoad {
  [super viewDidLoad];

  self.calendarView.delegate = self;
  self.calendarView.showMagnifier = YES;
  if (self.editItinerary) {
    NSDateComponents *components =
    [[NSCalendar currentCalendar] components:NSCalendarUnitYear |
                                             NSCalendarUnitMonth
                                    fromDate:self.editItinerary.startDate];
    components.day = 1;
    self.calendarView.firstDate = [[NSCalendar currentCalendar] dateFromComponents:components];
  } else {
    NSDateComponents *components =
        [[NSCalendar currentCalendar] components:NSCalendarUnitYear |
                                                 NSCalendarUnitMonth
                                        fromDate:[NSDate date]];
    components.day = 1;
    self.calendarView.firstDate = [[NSCalendar currentCalendar] dateFromComponents:components];
  }
  self.calendarView.lastDate = [NSDate dateWithTimeIntervalSinceNow:60*60*24*365]; // + 1 years
  self.calendarView.rowHeight =
      (CGRectGetWidth(self.view.bounds) - self.calendarView.padding * 2 + 30) / 7;
  [GLCalendarDayCell appearance].rangeDisplayMode = RANGE_DISPLAY_MODE_CONTINUOUS;

  NSString *title;
  if (self.location) { // It's creating
    title = self.location.shortName;
    [self.placeImageView sd_setImageWithURL:self.location.bigImageURL];
    self.deleteButton.hidden = YES;
  } else { // It's editing already existed itinerary
    title = self.editItinerary.location.shortName;
    [self.placeImageView sd_setImageWithURL:self.editItinerary.location.bigImageURL
     placeholderImage:[UIImage imageNamed:@"ph_town_big"]];
  }
  self.title = title;

  for (LOMItinerary *userItinerary in self.userItineraries) {
    GLCalendarDateRange *range =
        [GLCalendarDateRange rangeWithBeginDate:userItinerary.startDate
                                        endDate:userItinerary.endDate];
    range.editable = NO;
    range.backgroundColor = [UIColor colorWithRed:233.f/255.f
                                            green:233.f/255.f
                                             blue:233.f/255.f
                                            alpha:1.f];
    range.textColor = [UIColor whiteColor];
    [self.calendarView addRange:range];
  }

}

- (void)viewWillAppear:(BOOL)animated {
  [super viewWillAppear:animated];

  [self.calendarView reload];
  __weak LOMAddItineraryViewController *weakSelf = self;
  dispatch_async(dispatch_get_main_queue(), ^{
      // It have to be in main async block. Else it doesn't work.
      NSDate *dateToScroll;
      if (weakSelf.location) {
        dateToScroll = [NSDate date];
      } else {
        dateToScroll = weakSelf.editItinerary.startDate;
        GLCalendarDateRange *range =
        [GLCalendarDateRange rangeWithBeginDate:weakSelf.editItinerary.startDate
                                        endDate:weakSelf.editItinerary.endDate];
        range.editable = NO;
        range.backgroundColor = [UIColor colorWithRed:250.f/255.f
                                                green:132.f/255.f
                                                 blue:132.f/255.f
                                                alpha:1.f];
        range.textColor = [UIColor whiteColor];
        [weakSelf.calendarView addRange:range];
        weakSelf.currentRange = range;
      }
      [weakSelf.calendarView scrollToDate:dateToScroll animated:NO];
  });
}

I'd like the user to be able to select only one date range

I can do this by returning NO from:

- (BOOL)calenderView:(GLCalendarView *)calendarView canAddRangeWithBeginDate:(NSDate *)beginDate
  return NO;

}

However, it's then quite difficult for the user to select a new range to replace the old without deleting.

What I'd ideally like to achieve, is when the user selects a date outside of the current range, the existing range is deleted, and a new range is started where they click.

Is that possible?

Thanks

Hi, I'm using your control in one of my apps, and i found that i'm not able to select a date after 24 oct 2015. there is any specific reason why or it's a bug. when i try the app show an error. any help would be appreciate

If minimum date is set to today but falls on a day other than a sunday it is still possible to pick a date in the past. Possibility to 'grey out' and/or disable selecting of past dates on show?

Great pod! But I encountered a small problem...

I tried to integrate your calendar view in another app (through cocoa pods) and encountered this exception:

*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Could not load NIB in bundle: 'NSBundle </private/var/mobile/Containers/Bundle/Application/B235DCB6-6243-4A1D-A82A-EFAD5E27E930/myapp.app> (loaded)' with name 'GLCalendarDayCell''

This is because the .xib is loaded from the main bundle (bundle:nil) at GLCalendarView.m:81

[self.collectionView registerNib:[UINib nibWithNibName:@"GLCalendarDayCell" bundle:nil] forCellWithReuseIdentifier:CELL_REUSE_IDENTIFIER];

Changing this to this line instead, makes it work.

[self.collectionView registerNib:[UINib nibWithNibName:@"GLCalendarDayCell" bundle:[NSBundle bundleForClass:self.class]] forCellWithReuseIdentifier:CELL_REUSE_IDENTIFIER];

Would you be so kind as to update the pod with this fix?

Thanks a lot!

I'm trying to customize the first day of the week, to make it automatic. I want the first day of the week, is the system default.

How i can do it? Thanks.

Fix a timezone issue. In normal conditions, the calendar selection are NSDate corresponding to the 00:00 of the selected date. But if the timezone is changed after the GLCalendarView is instantiated, this NSDate may corresponds to other times (e.g. 23:00 if the timezone is one hour earlier)

Is there a way for us to change the red colour? Currently using those dayLabelAttributes, monthLabelAttributes are not helping as it seems to be forced casts it to bright red.
