iOS

Question

是否可以在 xCode 中的 Objective-C 中打开本机 iPhone "Add Event" 日历提示，其中已经填写了几个字段？例如姓名、地址和 start/end 日期？如果是这样，如何？这将允许用户仍然更改几个参数：他想什么时候收到警报等。

我环顾四周，但我只找到了无需用户确认即可自动添加事件的方法。

步骤 1 首先获取日历权限

dispatch_async(dispatch_get_main_queue(), ^{


    [self.eventManager.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {



        if(granted==NO)
        {

            BOOL permission=[[NSUserDefaults standardUserDefaults] boolForKey:@"CalendarPermissionAlert"];

            if(permission==NO) {

                kAppDelegateObject.eventManager.eventsAccessGranted=NO;

                [[NSUserDefaults standardUserDefaults]setBool:YES forKey:@"CalendarPermissionAlert"];

                UIAlertView   * alert = [[UIAlertView alloc] initWithTitle:@"Calendar Access is OFF"
                                                                   message:kCalenderResetMessage
                                                                  delegate:self
                                                         cancelButtonTitle:@"CANCEL"
                                                         otherButtonTitles:@"SETTING",nil];
                [alert show];
                alert.tag=101;

                return ;
            }


        }

步骤 2

//添加事件

-(void)addEventWithMessage:(NSString*)eventMessage withEventDate:(NSDate *)eventDate
 EKEventStore *eventStore;
 eventStore = [[EKEventStore alloc] init];

// 创建一个新的事件对象。 EKEvent *事件 = [EKEvent eventWithEventStore: eventStore];

// Set the event title.
event.title = eventMessage;

// Set its calendar.


NSString *identifier=[[NSUserDefaults standardUserDefaults]objectForKey:@"calenderId"]; //your application id 
 // NSLog(@"cal identifier: %@",identifier);
event.calendar = [eventStore calendarWithIdentifier:identifier];

//set Alarm
NSTimeInterval secondsInOneHours = 1 * 60 * 60;

NSDate *dateOneHoursAhead = [eventDate dateByAddingTimeInterval:secondsInOneHours];

// Set the start and end dates to the event.
event.startDate = eventDate;
event.endDate = dateOneHoursAhead; //

NSError *error;
    if ([eventStore saveEvent:event span:EKSpanFutureEvents commit:YES error:&error]) {

  //  NSLog(@"Event Added");
}
else{
    // An error occurred, so log the error description.
  //  NSLog(@"%@", [error localizedDescription]);
}

Answer 2

这是我处理它的方式...使用 EKEventEditViewController！

第一个：

@import EventKitUI;

在 .m 文件的最顶部。然后设置 EKEventEditViewDelegate

然后，当你想添加事件时，使用以下方法：

- (IBAction)addToCalendar:(id)sender {
    EKEventStore *eventStore = [[EKEventStore alloc] init];
    if ([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)])
    {
        // the selector is available, so we must be on iOS 6 or newer
        [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {
            dispatch_async(dispatch_get_main_queue(), ^{
                if (error)
                {
                    NSLog(@"%@", error);
                    // display error message here
                }
                else if (!granted)
                {
                    NSLog(@"%@ acce sdenied", error);
                    // display access denied error message here
                }
                else
                {
                    EKEvent *event = [EKEvent eventWithEventStore: eventStore];
                    event.title = nom;
                    event.location = adresse;

                    // Set the start and end dates to the event.
                    event.startDate = startDate;
                    event.endDate = endDate; //
                    EKEventEditViewController *eventViewController = [[EKEventEditViewController alloc] init];
                    eventViewController.event = event;
                    eventViewController.eventStore=eventStore;
                    eventViewController.editViewDelegate = self;
                    [event setCalendar:[eventStore defaultCalendarForNewEvents]];
                    [eventViewController setModalPresentationStyle:UIModalPresentationFullScreen];
                    [self presentViewController:eventViewController animated:YES completion:NULL];
                }
            });
        }];
    }
}

最后，添加这个委托方法来处理完成操作：

-(void)eventEditViewController:(EKEventEditViewController *)controller
         didCompleteWithAction:(EKEventEditViewAction)action {
    NSError *error;
    switch (action) {
        case EKEventEditViewActionCancelled:
            // User tapped "cancel"
            NSLog(@"Canceled");
            break;
        case EKEventEditViewActionSaved:
            NSLog(@"Saved");
            [controller.eventStore saveEvent:controller.event span: EKSpanFutureEvents error:&error];
            [calendarBouton setTitle:@"Ajouté!" forState:UIControlStateDisabled];
            calendarBouton.enabled = NO;
            break;
        case EKEventEditViewActionDeleted:
            // User tapped "delete"
            NSLog(@"Deleted");
            break;
        default:
            NSLog(@"Default");
            break;
    }

    [self dismissViewControllerAnimated:YES completion:nil];

}

iOS - 允许用户添加填写了某些字段的日历事件

iOS - allow user to add Calendar Event with some fields filled in
