使用iOS7，Apple发布了示例代码 DateCell 。

With iOS7, Apple released the sample code DateCell.

演示表格单元格中日期对象的格式化显示，并使用UIDatePicker编辑这些值。
作为此表的委托，该示例使用方法didSelectRowAtIndexPath打开UIDatePicker控件。

Demonstrates formatted display of date objects in table cells and use of UIDatePicker to edit those values. As a delegate to this table, the sample uses the method "didSelectRowAtIndexPath" to open the UIDatePicker control.

对于iOS 6.x及更早版本，UIViewAnimation是用于在屏幕上向下滑动UIDatePicker并在屏幕外向下滑动。对于iOS 7.x，UIDatePicker以内联方式添加到表视图中。

For iOS 6.x and earlier, UIViewAnimation is used for sliding the UIDatePicker up on-screen and down off-screen. For iOS 7.x, the UIDatePicker is added in-line to the table view.

UIDatePicker的action方法将直接设置自定义表格单元格的NSDate属性。此外，此示例演示如何使用NSDateFormatter类来实现自定义单元格的日期格式外观。

The action method of the UIDatePicker will directly set the NSDate property of the custom table cell. In addition, this sample shows how to use NSDateFormatter class to achieve the custom cell's date-formatted appearance.
