Ios 以编程方式设置事件标题

我正在尝试打开EKEventStore以在应用程序中设置提醒。已使用以下代码成功打开它

EKEventEditViewController *addController = [[EKEventEditViewController alloc] init];
addController.eventStore = self.eventStore;
addController.editViewDelegate = self;
[self presentViewController:addController animated:YES completion:nil];

但当我试图以编程方式添加EKEvent标题时，它没有出现在日历中

For adding title code is 

EKEvent *addEvent = [EKEvent eventWithEventStore:self.eventStore];
addEvent.title = [NSString stringWithFormat:@"%@", textcontainer.text];

EKReminder *reminder = [EKReminder reminderWithEventStore:eventStore];
reminder.location=@"Ludhiana";

但它不起作用。我做错什么了吗？请帮帮我

提前感谢。

感谢@satheeshwaran对我的提问的关注。但我通过以下方式解决了这个问题：

EKEvent *addEvent = [EKEvent eventWithEventStore:self.eventStore];
addEvent.title=[NSString stringWithFormat:@"%@", textcontainer.text];
EKEventEditViewController *addController = [[EKEventEditViewController alloc] init];
addController.eventStore = self.eventStore;
addController.event=addEvent;
addController.editViewDelegate = self;
[self presentViewController:addController animated:YES completion:nil];
