Question

我有一个应用程序所以我只是在我的应用程序中添加了一些事件或其余部分（足球比赛，电影）特定的日期和时间。这个添加事件我也想在iphone日历中显示。

感谢和问候。

Answer 1

你签出了EventKit吗？

Answer 2

您可以使用简单的JTCalender

首先，oyu必须包含项目的JT Calender框架

您必须在UIViewController中创建两个视图：

第一个视图是JTCalendarMenuView，它代表具有月份名称的部分。此视图是可选的。第二个视图是JTHorizontalCalendarView或JTVerticalCalendarView，它代表日历本身。你的UIViewController必须实现JTCalendarDelegate，所有方法都是可选的。

.h文件中的

#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


.m file

#import "ApptWindowView.h"
#import "SVProgressHUD.h"
