Have you checked out EventKit?

Answer 2

You can use simple JTCalender for this
first oyu have to include JT Calender framework for the project
You have to create two views in your UIViewController:
The first view is JTCalendarMenuView and it represents the part with the months names. This view is optional.
The second view is JTHorizontalCalendarView or JTVerticalCalendarView, it represents the calendar itself.
Your UIViewController have to implement JTCalendarDelegate, all methods are optional.
in .h file
#import <UIKit/UIKit.h>
#import "CustomTableViewCell.h"
#import "JTCalendar/JTCalendar.h"
#interface CalendarViewController : UIViewController<UITableViewDataSource,UITableViewDelegate,JTCalendarDelegate>
#property (strong, nonatomic) JTCalendarMenuView *calendarMenuView;
#property (strong, nonatomic) JTHorizontalCalendarView *calendarContentView;
#property (strong, nonatomic) JTCalendarManager *calendarManager;
#property (weak, nonatomic) IBOutlet NSLayoutConstraint *calendarContentViewHeight;
#end
