How to Effectively Use a DatePicker for Multiple UITextFields in Swift

When developing iOS applications, you may find yourself needing to allow users to select dates for multiple fields. One common challenge is using a single DatePicker for multiple UITextFields while ensuring each text field can have a different date. This guide is designed to guide you through this process and provide a clean solution.

The Problem Statement

Suppose you have three text fields for different date inputs: a "From Date", a "To Date", and a "Last Bid Date". Initially, if you use a shared DatePicker, all fields display the same date, making it impossible for users to set different dates individually. This can be frustrating and leads to a poor user experience.

The Solution

To solve this issue, you can configure the UIBarButtonItem for the Done button with tags. This ensures that when a date is selected, it gets updated only for the corresponding text field. Below, I’ll outline the steps to properly implement this solution.

Step-by-Step Implementation

Modify the addInputViewDatePicker Function

Update the addInputViewDatePicker function to accept a tag parameter for the doneBarButton. This tag will help identify which text field is currently active when the date selection is completed.

Update the doneButtonPressed Method

Next, update the doneButtonPressed method to use the tag of the UIBarButtonItem to determine which text field's date should be updated.

Implement in viewDidLoad

Finally, ensure you call addInputViewDatePicker for each text field in your viewDidLoad, providing unique tags for each one.

Conclusion

By following the steps outlined in this post, you will successfully allow users to select different dates for each text field using a single DatePicker. This enhancement not only improves usability but also promotes a cleaner design in your iOS application.

Feel free to tweak the code to fit your specific needs, and happy coding!
