Inline UIDatePicker or DateCell Example in Swift

With this blog post I am going to share with you how to add inline UIDatePicker or DateCell into your UITableView.

Originally the DateCell example was implemented by Apple as an Objective C project and is available for download here: Apple DateCell.

I googled around to see if there is already an implementation of DateCell in Swift language and have found quite a few projects already.  And since I am a big supporter of open source movement I preferred to pick one already available out there and used it in this video tutorial. And the reason I have selected the project is because it is the most identical Objective C to Swift conversion of Apple’s DateCell project I could find. So I picked it. Although, honestly I have found Apple’s implementation of DateCell project a bit confusing and think there is an easier way of achieving same results.

Here is how the final example will look like when we build and run our app:

Below are 3 video tutorials and a complete source code that demonstrate how to:

  • Build user interface to make inline UIDatePicker work with UITableView
  • Add Swift code from DateCell project
  • Customize UITableView to show how to add inline UIDatePicker to other table cells, how to change date format and how to get the selected date and time and convert it into NSDate object for further use.

Inline UIDatePicker or DateCell Source Code in Swift

You can download source code from github page:

import UIKit

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {

    let kPickerAnimationDuration = 0.40 // duration for the animation to slide the date picker into view
    let kDatePickerTag           = 99   // view tag identifiying the date picker view
    let kTitleKey = "title" // key for obtaining the data source item's title
    let kDateKey  = "date"  // key for obtaining the data source item's date value
    // keep track of which rows have date cells
    let kDateStartRow = 4
    let kDateEndRow   = 5
    let kDateCellID       = "dateCell";       // the cells with the start or end date
    let kDatePickerCellID = "datePickerCell"; // the cell containing the date picker
    let kOtherCellID      = "otherCell";      // the remaining cells at the end
    var dataArray: [[String: AnyObject]] = []
    var dateFormatter = NSDateFormatter()
    // keep track which indexPath points to the cell with UIDatePicker
    var datePickerIndexPath: NSIndexPath?
