Setup

To set up the Autocomplete bar, use the following steps:

  1. Create an instance of AceAutocompleteBar.
  2. Configure the appearance and behavior of the bar as desired.
  3. Associate the bar with your text input field using the cocoaTextField property.
  4. Optionally, implement delegate methods to handle user interactions.
“` let autocompleteBar = AceAutocompleteBar() autocompleteBar.configureAppearance() // Customize the look and feel autocompleteBar.cocoaTextField = yourTextField // Associate with your text field // Optional delegate methods autocompleteBar.delegate = self “`

Data Source

The Autocomplete bar can be populated with data by implementing the AceAutocompleteDataSource protocol. This allows you to control the suggestions displayed to the user based on the input.

“` class YourViewController: UIViewController, AceAutocompleteDataSource { // … func autocompleteBar(_ autocompleteBar: AceAutocompleteBar, suggestionsFor text: String, completion: @escaping ([AceAutocompleteItem]) -> Void) { // Provide suggestions based on input text let suggestions: [AceAutocompleteItem] = // Array of AceAutocompleteItem objects completion(suggestions) } } “`

Customization

AceAutocompleteBar provides a range of customization options to adapt the appearance and behavior to your application’s needs.

Appearance

To customize the appearance of the Autocomplete bar, you can use the following methods:

“` autocompleteBar.configureAppearance() // Use default appearance autocompleteBar.backgroundColor = .white // Change background color autocompleteBar.textColor = .black // Change text color // … Add more customization options “`

Behavior

The behavior of the Autocomplete bar can also be modified according to your requirements. Here are some examples:

“` autocompleteBar.minCharactersToTrigger = 1 // Set the minimum characters needed to display suggestions autocompleteBar.minCharactersIgnored = 2 // Set the minimum characters ignored before capturing new suggestions // Limit suggestions count autocompleteBar.maxNumberOfSuggestions = 5 // Set the maximum number of suggestions to display // Set delay for suggestions update autocompleteBar.suggestionsUpdateDelay = 0.5 // Specifies the time delay (in seconds) before updating the suggestions after typing // … Add more behavior-related customization options “`

Delegate

The AceAutocompleteBar library offers delegate methods that allow you to handle user interactions and respond to changes. Implement the following methods in your view controller to access these functionalities:

“` class YourViewController: UIViewController, AceAutocompleteDelegate { // … func autocompleteBar(_ autocompleteBar: AceAutocompleteBar, didSelect item: AceAutocompleteItem) { // Handle selection of an item from the suggestions list } func autocompleteBarDidShow(_ autocompleteBar: AceAutocompleteBar) { // Perform custom actions when the Autocomplete bar is shown } func autocompleteBarDidHide(_ autocompleteBar: AceAutocompleteBar) { // Perform custom actions when the Autocomplete bar is hidden } // … Implement more delegate methods as needed } “`

These methods provide you with flexibility to react to user interactions and incorporate additional behaviors into your application.

Frequently Asked Questions

How can I clear the suggestions list programmatically?

You can clear the suggestions list by calling the clearSuggestions() method of the Autocomplete bar:

“` autocompleteBar.clearSuggestions() “`

Can I customize the appearance of an individual suggestion?

Yes, you can customize each suggestion’s appearance by implementing the AceAutocompleteDataSource protocol and providing a custom UITableViewCell in the AceAutocompleteItem‘s cell property. Ensure that your custom cell conforms to the AceAutocompleteItemCell protocol:

“` func autocompleteBar(_ autocompleteBar: AceAutocompleteBar, suggestionsFor text: String, completion: @escaping ([AceAutocompleteItem]) -> Void) { // Provide suggestions with custom cells let suggestions: [AceAutocompleteItem] = // Array of AceAutocompleteItem objects completion(suggestions) } class CustomSuggestionCell: UITableViewCell, AceAutocompleteItemCell { // … } “`

Can I set a placeholder for the Autocomplete bar?

Yes, you can use the cocoaTextField property of the Autocomplete bar to set a placeholder for the underlying text field:

“` autocompleteBar.cocoaTextField.placeholder = “Enter a value…” “`

How can I handle the event when the user taps outside the Autocomplete bar?

You can detect when the user taps outside the Autocomplete bar by implementing the touchesBegan(_:with:) method in your view controller:

“` override func touchesBegan(_ touches: Set, with event: UIEvent?) { super.touchesBegan(touches, with: event) // Dismiss the Autocomplete bar autocompleteBar.dismiss() } “`

Can I customize the behavior when a suggestion is selected?

Yes, you can modify the behavior when a suggestion is selected by implementing the autocompleteBar(_:didSelect:) delegate method. You can programmatically perform an action, update other UI elements, or handle the selection in any desired way:

“` func autocompleteBar(_ autocompleteBar: AceAutocompleteBar, didSelect item: AceAutocompleteItem) { // Update UI or perform custom action based on the selected suggestion yourTextField.text = item.title // … Add your desired behavior } “`

Conclusion

The AceAutocompleteBar library provides a flexible and customizable solution for implementing an Autocomplete bar in your iOS applications. By following the installation instructions and utilizing the various features, you can enhance user experience and simplify data entry within your app.
