问题描述

更改NSDatePicker的值后如何通知我?

How would I get notified of a value of a NSDatePicker, when it's changed?

推荐答案

我仅在使用UIDatePicker的iPhone上完成了此操作,但在Mac上却类似,您注册为委托并接收消息.请参阅此处是Apple的文档.

I've only done it on the iPhone with UIDatePicker but it is similar on the Mac, you register as a delegate and receive messages. See Apple's Docs here.

我应该澄清一下,它告诉您更改的时间,您仍然需要调用-dateValue来获取日期.

I should clarify, this tells you when it changed, you still need to call -dateValue to get the date.
