Add the following import to the top of your Swift file which needs a dropdown textfield.

   import ZTDropDownTextField

IBOutlet

You can declare a ZTDropDownTextField with an IBOutlet and connect it to your storyboard or nib file.

  @IBOutlet weak var dropDownTextField: ZTDropDownTextField!

DataSourceDelegate

There are 3 delegate methods which you have to implement, if your view controller conform with ZTDropDownTextFieldDataSourceDelegate.

You can let your view controller become a ZTDropDownTextFieldDataSourceDelegate by doing the following:

  dropDownTextField.dataSourceDelegate = self

Example of implementing ZTDropDownTextFieldDataSourceDelegate method

extension ViewController: ZTDropDownTextFieldDataSourceDelegate {
    func dropDownTextField(dropDownTextField: ZTDropDownTextField, numberOfRowsInSection section: Int) -> Int {
        return myList.count
    }

    func dropDownTextField(dropDownTextField: ZTDropDownTextField, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        var cell = dropDownTextField.dropDownTableView.dequeueReusableCellWithIdentifier("Cell") as? UITableViewCell
        if cell == nil {
            cell = UITableViewCell(style: .Default, reuseIdentifier: "Cell")
        }

        cell!.textLabel!.text = myList[indexPath.row]

        return cell!
    }

    func dropDownTextField(dropdownTextField: ZTDropDownTextField, didSelectRowAtIndexPath indexPath: NSIndexPath) {
       println("drop down list row did select")
    }
}

}
  dropDownTextField.animationStyle = .Slide
