我正在关注here的教程,其中包括带有通知的事件管理和所有内容。现在的问题是我在以下代码中遇到错误

我的.h文件

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


@interface ViewController : UIViewController

- (IBAction) NewEvent:(id)sender;


@end

我的.m文件

#import "ViewController.h"
#import <EventKit/EventKit.h>

@interface ViewController ()

@end

@implementation ViewController

- (IBAction) NewEvent:(id)sender {

    EKEventStore *eventDB = [[EKEventStore alloc] init];
    EKEventStore *myEvent = [EKEvent eventWithEventStore:eventDB];

    myEvent.title = @"New Event"; // <-- Errors are appearing hear as shown in the title.


}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

@end

其他信息: 我已经添加了框架工作,但仍然在代码中显示错误。代码名称是

  

在“eventstore”类型的对象上找不到属性“title”

您需要仔细检查myEvent是否为正确类型(EKEvent *而不是EKEventStore *)并且您实际上是在尝试设置{{1而不是myEvent。您发布的错误表示您在事件存储中设置eventDB,而不仅仅是事件。
