推荐答案

在 iOS7 中，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以及使用 UIDatePicker 编辑这些值.作为此表的委托，示例使用didSelectRowAtIndexPath"方法打开 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 用于在屏幕上向上滑动 UIDatePicker，在屏幕外向下滑动.对于 iOS 7.x，UIDatePicker 内嵌添加到表格视图中.

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方法会直接设置自定义表格单元格的NSDate属性.此外，本示例展示了如何使用 NSDateFormatter 类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.
