The code example, DateCell demonstrates how to display UIPickerViews inline, which is the suggested UIPickerView display method since iOS 7, instead of in modal views or in action sheets. The problem with this example is the code is poorly written and difficult to understand. This code was first written 5 years ago in 2009, and during that time I'm certain new features and bug fixes were added by different developers which may have caused the confusing codebase.

Apple's DateCell example comes with support for iOS 6.1. I removed this feature because 1) my apps target iOS 7 and beyond, and 2) the fewer lines of code to read the easier it will be for you to understand.

I spent 3 hours editing this code:

• Removed unused variables and uneccessary logic,
• Renamed variables so they actually describe the values which they hold
• Added my own comments and removed comments which we unclear
• Removed unused conditions
• Removed support for iOS 6.1
• Converted if statements to switch statements wherever I could. I believe switch statements to be easier to read.
• Set XCode to hard-mode and compiled the project, resulting in 0 warnings and errors
• Added support for sizeclasses in Storyboard, because why not?

Demonstrates formatted display of date objects in table cells and use of UIDatePicker to edit those values.

Using a grouped style UITableViewController, the sample has two UITableViewCells to draw the primary title and NSDate values. This is accomplished using the built-in cell type "UITableViewCellStyleValue1" which supports left and right text.

As a delegate to this table, the sample uses the method "didSelectRowAtIndexPath" to open the UIDatePicker control.

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.

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.

Xcode 5.0, iOS SDK 7.0
