EKEventEditViewController 不支持被推送到 NavController 吗？请参阅附加的代码和错误。

我可以以模态方式呈现 EKEventEditViewController，但是当我尝试通过导航控制器推送时，出现以下错误：

*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'

代码是：

EKEventEditViewController *addController = [[[EKEventEditViewController alloc] initWithNibName:nil bundle:nil] autorelease];
addController.eventStore = self.eventStore;
addController.editViewDelegate = self;

[self.navigationController pushViewController:addController animated:TRUE];   // ERROR HERE

EKEventEditViewController 是 UINavigationController 的子类，所以它不能被推送到另一个 UINavigationController。

EKEventEditViewController 应该以模态方式呈现。

EKEventEditViewController 类参考

如果您正在寻找一些代码来启动 iPad-with-popover 实现：

EKEventStore *eventStore [[EKEventStore alloc] init];
EKEventEditViewController *eventController = [[EKEventEditViewController alloc] init];
eventController.editViewDelegate = self; 
eventController.eventStore = eventStore;

EKEvent *event  = [EKEvent eventWithEventStore: eventStore];
event.title     = @"New Event";
event.startDate = [[NSDate alloc] init];
event.endDate   = [[NSDate alloc] initWithTimeInterval: 60 * 60 sinceDate: event.startDate];
eventController.event = event;

/* You can add EKEventEditViewController directly to the popover -- this had me baffled for _hours_ */
popover = [[UIPopoverController alloc] initWithContentViewController: eventController];

当用户完成或取消事件编辑时，您还需要包含此委托方法来执行您需要执行的任何操作：

- (void) eventEditViewController: (EKEventEditViewController *)controller didCompleteWithAction: (EKEventEditViewAction)action 
{
    EKEvent *thisEvent = controller.event;

    switch (action) {
        case EKEventEditViewActionCanceled:
            NSLog(@"Canceled action");
            break;

        case EKEventEditViewActionSaved:
            NSLog(@"Saved action: %@", thisEvent.startDate);
            break;

        case EKEventEditViewActionDeleted:
            NSLog(@"Deleted action");
            break;

        default:
            break;
    }

    [popover dismissPopoverAnimated: YES];
}

享受！

对于未来的读者：

EKEventEditViewController 是一个 UINavigationController 所以你可以说：

EKEventEditViewController *controller = [[EKEventEditViewController alloc] init];

// Set your properties here

[self.navigationController pushViewController:controller.viewControllers[0] animated:YES];

这对我有用，但我不知道你是否可以为 Apple 做到这一点。
