EventKit提醒

Question

我正在努力学习EventKit提醒的基础知识。我正在尝试在这里重新创建教程：http://www.techotopia.com/index.php/Using_iOS_6_Event_Kit_to_Create_Date_and_Location_Based_Reminders

但是，当我尝试构建项目时，我在IBAction和CreateReminder的.m文件中都得到了“缺少方法声明的上下文”的错误。我试着在这里寻求建议，但似乎仍然找不出我做错了什么。如果这些教程总是遗漏了一些阻止它构建的基本信息，那么我不得不说这些教程有什么用。如果有人能帮上忙，我将不胜感激。

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

@interface ReminderAppFirstViewController : UIViewController

@property (strong, nonatomic) EKEventStore *eventStore;

@property (strong, nonatomic) IBOutlet UIDatePicker *myDatePicker;
@property (strong, nonatomic) IBOutlet UITextField *reminderText;
- (IBAction)setReminder:(id)sender;
- (void)createReminder;
@end

- (IBAction)setReminder:(id)sender {

    if (_eventStore == nil)
    {
        _eventStore = [[EKEventStore alloc]init];
        [_eventStore requestAccessToEntityType:EKEntityTypeReminder comnpletion: ^(BOOL granted, NSError *error) ] {
            if (!granted)
                NSLog(@"Access to store not granted");
        }];

    }

    if (_eventStore != nil)
        [self createReminder];
}



- (void)createReminder
{
    EKReminder *reminder = [EKReminder
                            reminderWithEventStore:self.eventStore];

    reminder.title = _reminderText.text;

    reminder.calendar = [_eventStore defaultCalendarForNewReminders];

    NSDate *date = [_myDatePicker date];

    EKAlarm *alarm = [EKAlarm alarmWithAbsoluteDate:date];

    [reminder addAlarm:alarm];

    NSError *error = nil;

    [_eventStore saveReminder:reminder commit:YES error:&error];

    if (error)
        NSLog(@"error = %@", error);

        }

下面的部分看起来应该在.h文件中，而不是.m中。在接口的@ .m部分中声明的属性本质上是私有的，只能在.m中访问。这些方法也不合时宜。也许是教程中的一个错误。

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

@interface ReminderAppFirstViewController : UIViewController

@property (strong, nonatomic) EKEventStore *eventStore;

@property (strong, nonatomic) IBOutlet UIDatePicker *myDatePicker;
@property (strong, nonatomic) IBOutlet UITextField *reminderText;
- (IBAction)setReminder:(id)sender;
- (void)createReminder;
@end
