UITextFieldPickerInput

This is a small library to help displaying picker as input view for UITextField with some editable and managable content

Installation

The lib is available through CocoaPods CocoaPods can be installed using Ruby gems:

$ gem install cocoapods

Then simply add UITextFieldPickerInput to your Podfile:

pod 'UITextFieldPickerInput'

Usage

1- Make your model or data type confirms to Selectable protocol

in case you want the selectabel data to be custom model:

struct Cat {
    
    var id: Int
    var name: String
    var extraInfo: String
}

extension Cat: Selectable {
    
    var selectableValue: Any {
        return id
    }
    
    var selectableText: String {
        return name
    }
}

or for example simple data type as String:

extension String: Selectable {

    var selectableText: String {
        return self
    }
    
    var selectableValue: Any {
        return self
    }
}

2- Define your data that you want to select from

the key will be the component number and the value will be array of objects that you want to select from.

let data: [Int: [Selectable]] = [
  0: [Cat(id: 1, name: "cat1", extraInfo: "asdasd"), Cat(id: 2, name: "cat2", extraInfo: "asdasd")],
  1: [Dog(id: 1, name: "dog1", extraInfo: "asdasd"), Dog(id: 2, name: "dog2", extraInfo: "asdasd")]
 ]

3- load the Picker inside the UITextfiled and get the selected values for each component

textField.loadPicker(data: data, onSelect: { [weak self] selected in
    var displayedText = ""
    
    if let selectedCat = selected[0] as? Cat {
        displayedText = "Cat: \(selectedCat.name)"
    }
    if let selectedDog = selected[1] as? Dog {
        displayedText.append(" Dog: \(selectedDog.name)")
    }
              
    self?.textField.text = displayedText
  }) { selectedDone in
        print(selectedDone)
}

textField.becomeFirstResponder()

Customize UI and update data

If you want to change the UI (as colors or texts ...) you can use the PickerInputSettings

This will allow you to update the following props and it's default values

     cancelButtonTitle: String = "Cancel"
     doneButtonTitle: String = "Done"
     toolBarStyle: UIBarStyle = .black
     toolBarIsTranslucent: Bool = true
     toolBarTintColor: UIColor = .black
     toolBarBarTintColor: UIColor = .lightGray
     hideDoneButton: Bool = false
     hideCancelButton: Bool = false
     isToolBarHidden: Bool = false
     hideWhenSelect: Bool = false

for example

   var settings: PickerInputSettings = PickerInputSettings()
   settings.cancelButtonTitle = "new Title"
   settings.hideWhenSelect = true
   textField.updatePickerInput(with: settings)

You can update data for specific component by using

textField.updatePickerInput(with: [Cat(id: 1, name: "updated cat 1", extraInfo: "foo"),
                                 Cat(id: 2, name: "updated cat 2", extraInfo: "foo")],
                                 component: 0)

Or update all component

Just define a new data and pass it to

textField.updatePickerInput(with: [Int : [Selectable]])
