Usage

Initialization

YourViewController.h

#import <UIKit/UIKit.h>
#import <QHCarouselCalendar.h>

@interface YourViewController : UIViewController <QHCarouselCalendarDataSource, QHCarouselCalendarDelegate>
@property (strong, nonatomic)QHCarouselCalendar *calendar;
@end

YourViewController.m

    self.calendar = [[QHCarouselCalendar alloc] initWithFrame:someFrame]; // someFrame is the frame that you want to give to your calendar. Most likely self.view.frame
    self.calendar.dataSource = self;
    self.calendar.delegate = self;
    [self.view addSubview:self.calendar];

Data Source

QHCarouselCalendarDataSource

REQUIRED: View For Calendar

This method is called to get the view for each day. (Think about cellForRowAtIndexPath from UITableViewController)

  -(UIView*)viewForCalendar:(QHCarouselCalendar*)calendar forDate:(NSDate*)date withSuperviewFrame:(CGRect)frame reusingView:(UIView*)view;

OPTIONAL: Special dates

This method allows to flag a specific date as "special". It will have a different look on the day part of the calendar.

  -(BOOL)calendar:(QHCarouselCalendar*)calendar isDateSpecial:(NSDate*)date;

Delegate

QHCarouselCalendarDelegate

OPTIONAL: The selected date has changed

-(void)calendar:(QHCarouselCalendar*)calendar didChangeSelectedDate:(NSDate*)date;

OPTIONAL: Specify custom attributes for the calendar (possible attributes are listed below)

-(NSDictionary *)QHCarouselCalendarAttributesForCalendar:(QHCarouselCalendar*)calendar; 

Attributes

To change the calendar's behavior and/or look and feel, you need to implement the following delegate's method:

-(NSDictionary *)QHCarouselCalendarAttributesForCalendar:(QHCarouselCalendar*)calendar{
    return @{
             QHCarouselCalendarContentCarouselBackgroundColor : [UIColor clearColor],
             QHCarouselCalendarDayCarouselBackgroundColor : [UIColor colorWithRed:0 green:0 blue:0 alpha:0.2],
             QHCarouselCalendarMonthCarouselBackgroundColor : [UIColor colorWithRed:0 green:0 blue:0 alpha:0.5],
             QHCarouselCalendarYearCarouselBackgroundColor : [UIColor colorWithRed:0 green:0 blue:0 alpha:1],
             QHCarouselCalendarYearCarouselHeight : [NSNumber numberWithFloat:0.0f]
             ... // and any other property that you want to customize (see below)
             };
}
