迴應「取消」或「完成」的EKEventEditViewController

Question

我使用的是EKEventEditViewController這我能夠與信息，我需要填充。我被授予訪問日曆和一切。我的問題是當我點擊「取消」時沒有任何反應。當我點擊「完成」時，我收到一個錯誤，說沒有設置日曆，沒有設置日期，「事件不屬於該事件存儲」。

我不認爲我的didCompleteWithAction委託方法被調用。

我的viewController符合：

@interface EventoViewController : UIViewController <EKEventEditViewDelegate> 

當我嘗試設置自己爲委託我得到的錯誤：

sending EventoViewController *const__strong' to parameter of incompatible type 'id<UINavigationControllerDelegate>' 

原始代碼的.h

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

@interface EventoViewController : UIViewController <EKEventEditViewDelegate> 

@property (weak, nonatomic) IBOutlet UILabel *eventDetailTitleLabel; 
@property (weak, nonatomic) IBOutlet UILabel *eventDetailDateLabel; 
@property (weak, nonatomic) IBOutlet UILabel *eventDetailDescriptionLabel; 


- (IBAction)closeModalView:(id)sender; 
- (IBAction)addEventToNative:(id)sender; 


@end

您需要將您的視圖控制器類中的self分配給控制器上的editViewDelegate屬性 - EKEventEditViewController類是UINavigationController的子類，因此繼承的委託屬性用於處理導航事件。希望有所幫助。

- (void)presentEventEditViewControllerWithEventStore:(EKEventStore*)eventStore { 
    EKEventEditViewController* eventEditVC = [[EKEventEditViewController alloc] init]; 
    eventEditVC.eventStore = eventStore; 
    // Add this line: 
    eventEditVC.editViewDelegate = self;
