• Everything you need resides in the Source directory. Add those files to your project.
• Alternatively, drag ICInputAccessory.xcodeproj to your app project as a subproject. Add ICInputAccessory-iOS to the Target Dependencies in the application target’s Build Phases settings.

Usage

KeyboardDismissTextField

let textField = KeyboardDismissTextField(frame: rect)

TokenField

let tokenField = TokenField(frame: rect)
tokenField.delegate = self as? TokenFieldDelegate

The characters that complete a token:

/// Characters that complete a new token, defaults are whitespace and commas.
public var delimiters: [String]

Tokens:

/// Texts of each created token.
public var texts: [String] { get }

/// Creates a token with the current input text.
public func completeCurrentInputText()

/// Removes the input text and all displayed tokens.
public func resetTokens()

UI customization:

/// The image on the left of text field.
public var icon: UIImage? { get set }

/// The placeholder with the default color and font.
public var placeholder: String? { get set }

/// The placeholder with customized attributes.
public var attributedPlaceholder: NSAttributedString? { get set }

/// Customized attributes for tokens in the normal state, e.g. .font and .foregroundColor.
public var normalTokenAttributes: [NSAttributedStringKey : NSObject]? { get set }

/// Customized attributes for tokens in the highlighted state.
public var highlightedTokenAttributes: [NSAttributedStringKey : NSObject]? { get set }

Customizable properties in storyboard:

@IBInspectable var icon: UIImage?
@IBInspectable var placeholder: String?
@IBInspectable var textColor: UIColor?
@IBInspectable var cornerRadius: CGFloat

See Example/CustomizedTokenField.swift for more details.

TokenFieldDelegate

TokenField currently notifies its delegate the following events:

@objc optional func tokenFieldDidBeginEditing(_ tokenField: TokenField)
@objc optional func tokenFieldDidEndEditing(_ tokenField: TokenField)
@objc optional func tokenFieldWillReturn(_ tokenField: TokenField)
@objc optional func tokenField(_ tokenField: TokenField, didChangeInputText text: String)
@objc optional func tokenField(_ tokenField: TokenField, shouldCompleteText text: String) -> Bool
@objc optional func tokenField(_ tokenField: TokenField, didCompleteText text: String)
@objc optional func tokenField(_ tokenField: TokenField, didDeleteText text: String, atIndex index: Int)

The displayed delimiter string can be customized by:

@objc optional func tokenField(_ tokenField: TokenField, subsequentDelimiterForCompletedText text: String) -> String

OptionPickerControl

An example type that conforms to OptionDescriptive:

extension String: OptionDescriptive {

  var title: String {
    return self
  }

  static var titleForOptionalValue: String {
    return "(optional)"
  }

}

To initialize OptionPickerControl with CGRect.zero and add it to the view hierarchy:

let optionPicker = OptionPickerControl<String>()
optionPicker.options = [.optional, Option("Option 1"), Option("Option 2")]
optionPicker.addTarget(self, action: #selector(didChangeOption(_:)), for: .valueChanged)
view.addSubview(optionPicker)

To show the UIPickerView:

optionPicker.becomeFirstResponder()
