如何將事件標題（從UI文本視圖）添加到由我的APP創建的日曆事件？

Question

我開發了一個應用程序，我的應用程序需要在設備的日曆上創建一個事件。我一直在通過EventKitProgGuide並研究了SimpleEKDemo。

通過簡化SimpleEKDemo中的代碼，我生成了下面顯示的代碼，它直接從我的應用程序打開'日曆的事件屏幕'並正確生成事件。我很確定。

現在我需要使用UITextView的文本內容作爲事件標題！

有人可以幫助我與該代碼？

感謝，

這裏是我的代碼：

@.h 
#import <EventKitUI/EventKitUI.h> 
#import <EventKit/EventKit.h> 

@property (nonatomic, strong) EKEventStore *eventStore; 
@property (nonatomic, strong) EKEvent *event; 
@property (nonatomic, strong) EKCalendar *defaultCalendar; 
@property (nonatomic, strong) 
IBOutlet UITextView *textView1; 
- (IBAction)agendar:(UIButton *)sender; 

@.m 

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
self.eventStore = [[EKEventStore alloc]init]; 
self.textView1.text = @"hello world!"; 
} 


-(void)viewDidAppear:(BOOL)animated 
{ 
[super viewDidAppear:animated]; 
[self checkEventStoreAccessForCalendar]; 
} 


- (IBAction)agendar:(UIButton *)sender { 
EKEventEditViewController *addController = [[EKEventEditViewController alloc] init]; 
addController.eventStore = self.eventStore; 
addController.editViewDelegate = self; 
[self presentViewController:addController animated:YES completion:nil]; 
self.event = [EKEvent eventWithEventStore:self.eventStore]; 

// Jeff's suggested code: 
self.event.title = self.textView1.text; 

// Jeff's SaveEvent Sugestion 
NSError *err; 
[self.eventStore saveEvent:self.event span:EKSpanThisEvent error:&err]; 


} 


-(void)checkEventStoreAccessForCalendar 
{ 
EKAuthorizationStatus status = [EKEventStore authorizationStatusForEntityType:EKEntityTypeEvent]; 

switch (status) 
{ 
    case EKAuthorizationStatusAuthorized: [self accessGrantedForCalendar]; 
     break; 

    case EKAuthorizationStatusNotDetermined: [self requestCalendarAccess]; 
     break; 


    case EKAuthorizationStatusDenied: 
    case EKAuthorizationStatusRestricted: 
    { 
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Alerta de Privacidade" message:@"Permissão de acesso ao calendário não concedida." 
                 delegate:nil 
               cancelButtonTitle:@"OK" 
               otherButtonTitles:nil]; 
    [alert show]; 
    } 
     break; 
    default: 
     break; 
} 
} 


-(void)requestCalendarAccess 
{ 
    [self.eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) 
    { 
     if (granted) 
     { 
      Tela8ViewController * weakSelf = self; 

      dispatch_async(dispatch_get_main_queue(), ^{ 

      [weakSelf accessGrantedForCalendar]; 
      }); 
     } 
    }]; 
} 


-(void)accessGrantedForCalendar 
{ 
    self.defaultCalendar = self.eventStore.defaultCalendarForNewEvents; 
} 

- (void)eventEditViewController:(EKEventEditViewController *)controller 
     didCompleteWithAction:(EKEventEditViewAction)action 
{ 

    [self dismissViewControllerAnimated:YES completion:^ 
    { 
     if (action != EKEventEditViewActionCanceled) 
     { 
       dispatch_async(dispatch_get_main_queue(), ^{ 

      }); 
     } 
    }]; 
}

有兩種方法可以使用EventKit創建事件。你的示例代碼目前有兩種組合，所以你應該選擇一個！

答：創建一個事件，其中包含預設的某些字段（在您的情況下，標題），並允許用戶使用EKEventEditViewController查看並保存它（或選擇取消並放棄它）。在這種情況下，您的代碼不需要提交事件 - 只需注意代表響應以確認它發生了。

- (void)createEventWithTitle:(NSString *)title 
{ 
    EKEvent *newEvent = [EKEvent eventWithEventStore:self.eventStore]; 
    newEvent.title = title; 

    EKEventEditViewController *controller = [[EKEventEditViewController alloc] init]; 
    controller.eventStore = self.eventStore; 
    controller.event = newEvent; 
    controller.editViewDelegate = self; 

    [self presentViewController:controller animated:YES completion:nil]; 
} 

// EKEventEditViewController delegate method 

- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action 
{ 
    if (action == EKEventEditViewActionSaved) { 
     // event has been committed 
    } 
    // alternatives are EKEventEditViewActionCanceled, EKEventEditViewActionDeleted 
    [self dismissViewControllerAnimated:YES completion:Nil]; 
} 

B.您可以創建一個事件，並完全在你的代碼提交它，如果你不需要用戶參與。在這種情況下，您可以使用EKEventStore saveEvent: span: error:而不是依靠EKEventEditViewController。

您是否嘗試過類似

self.event.title = self.textView1.text; 

？
