[英]iOS EKEventEditViewController how do I force the Alert to “At time of event”?
[英]iOS: How to get the identifier of an event, which was created via a call to EKEventEditViewController
在我的應用程序中,用戶可以創建事件。 這是通過向用戶展示用於創建事件的iOS UI來實現的:
- (IBAction)addTermin:(id)sender
{
// Create an instance of EKEventEditViewController
EKEventEditViewController *addController = [[EKEventEditViewController alloc] init];
// Set addController's event store to the current event store
addController.eventStore = self.eventStore;
addController.editViewDelegate = self;
[self presentViewController:addController animated:YES completion:nil];
}
因此,我實現了委托方法:
- (void)eventEditViewController:(EKEventEditViewController *)controller
didCompleteWithAction:(EKEventEditViewAction)action
{
MRHomeViewController * __weak weakSelf = self;
// Dismiss the modal view controller
[self dismissViewControllerAnimated:YES completion:^
{
if (action != EKEventEditViewActionCanceled)
{
dispatch_async(dispatch_get_main_queue(), ^{
// Re-fetch all events happening in the next 24 hours
weakSelf.eventsList = [self fetchEvents];
// Update the UI with the above events
[weakSelf.termineTableView reloadData];
});
}
}];
}
因此,稍后我想檢索用戶創建的事件。 我當時在想,在某種程度上,在委托方法中,我可以獲得對新創建事件的引用?
還是有另一種方法來稍后僅提取用戶創建的事件?
為此,您需要首先創建一個新的EKEvent,保留對其的引用,並將其傳遞到EKEventEditViewController中:
self.newEvent = [EKEvent eventWithEventStore:self.eventStore];
addController.event = newEvent;
在委托方法中,檢查EKEventEditViewActionSaved
,然后查閱self.newEvent
來查找所需的事件。 如果要維護對事件的長期引用,可以存儲eventIdentifier
或其他字段以供以后查找。
