Question

我正在使用一个EKEventEditViewController，我可以填充我需要的信息。我被授予访问日历和所有内容的权限。我的问题是当我点击“取消”没有任何反应。当我点击“完成”时，我收到一条错误消息，表示没有设置日历，没有设置日期，“事件不属于该事件存储”。

我认为我的didCompleteWithAction委托方法没有被调用。

我的viewController符合：

@interface EventoViewController : UIViewController <EKEventEditViewDelegate>

当我尝试将self设置为委托时，我收到错误：

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

原始代码.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

原创.m

#import "EventoViewController.h"



@implementation EventoViewController

@synthesize eventDetailTitleLabel, eventDetailDateLabel, eventDetailDescriptionLabel;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad { [super viewDidLoad]; }

- (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; }

- (IBAction)closeModalView:(id)sender { [self dismissModalViewControllerAnimated:YES]; }

- (IBAction)addEventToNative:(id)sender {
NSLog(@"Clicked ");
EKEventStore *eventStore = [[EKEventStore alloc] init];

if([eventStore respondsToSelector:@selector(requestAccessToEntityType:completion:)]) {
    // iOS 6 and later
    [eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error) {

        // perform the main thread here to avoid any delay. normally seems to be 10 to 15 sec delay.
        [self performSelectorOnMainThread: @selector(presentEventEditViewControllerWithEventStore:) withObject:eventStore waitUntilDone:NO];



        if (granted){
            NSLog(@"We are granted to access Calendars!");
            //---- codes here when user allow your app to access theirs' calendar.

        }
        else {
            //---- code for no permission
            NSLog(@"We have no permission to access calendars!");
        }
    }];
}
}

- (void)presentEventEditViewControllerWithEventStore:(EKEventStore*)eventStore {
EKEventEditViewController* eventEditVC = [[EKEventEditViewController alloc] init];
eventEditVC.eventStore = eventStore;

EKEvent* event = [EKEvent eventWithEventStore:eventStore];
event.title = self.eventDetailTitleLabel.text;
event.startDate = [NSDate date];
event.endDate = [NSDate date];

event.notes = @"Evento SAT";
event.allDay = YES;
eventEditVC.event = event;

//eventEditVC.delegate = (id)self;
[self presentViewController:eventEditVC animated:YES completion:nil];
}


- (void)eventEditViewController:(EKEventEditViewController *)controller didCompleteWithAction:(EKEventEditViewAction)action {
    NSLog(@"Clicked Cancel or Done");
    [self dismissModalViewControllerAnimated:YES];

您需要将视图控制器类中的self分配给控制器上的 editViewDelegate 属性 - EKEventEditViewController类是UINavigationController的子类，因此继承的委托属性用于处理导航事件。希望有所帮助。

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

响应EKEventEditViewController中的“取消”或“完成”
