Overview

AutocompleteField

CocoaPods Compatible Platform

Subclass of UITextField that shows inline suggestions while typing.

  • Plug and play replacement for UITextField.
  • Delimiter support. Perfect when autocompleting email addresses.
  • Two suggestion modes (word and sentence, see API below).
  • Works with custom fonts, borders etc.
  • Super lightweight and zero dependencies.

AutocompleteField

Requirements

  • iOS 10.0+
  • Swift 4.2+

Installation

CocoaPods

Add the following to your Podfile:

target 'MyApp' do
  pod 'AutocompleteField', '~> 2.0'
end

Swift Package Manager

  • Select File > Swift Packages > Add Package Dependency.
  • Enter https://github.com/filipstefansson/AutocompleteField.git in the Choose Package Repository dialog.

See Apple docs for more information.

Manually

  • Copy /Sources/AutocompleteField.swift to your project. There are no other dependencies.

Usage

You use this textfield in the same way as the regular UITextField, through Storyboards or programmatically.

Basic

import AutocompleteField

...

let textfield = AutocompleteField(frame: CGRect(x: 20, y: 20, width: 200, height: 40))
textfield.placeholder = "Name"

textfield.suggestions = [
  "George Washington",
  "Thomas Jefferson",
  "John Adams",
  "Theodore Roosevelt",
  "John F. Kennedy",
  "George W. Bush",
]

self.view.addSubview(textfield)

Delimiter

The delimiter can be used to only suggest an autocompletion after a specific character is found in the string. In this example we look for the @ character, and then provide suggestions for email providers.

import AutocompleteField

...

// email textfield autocompleting email providers
let textfield = AutocompleteField(frame: CGRect(x: 20, y: 20, width: 200, height: 40))
textfield.placeholder = "Email"
textfield.keyboardType = .emailAddress

textfield.suggestions = [
  "gmail.com",
  "icloud.com",
  "outlook.com",
]

// add the delimiter
textfield.delimiter = "@"

self.view.addSubview(textfield)

API

Property Type Description
suggestionColor UIColor The color of the suggestion. Defaults to the default placeholder color.
suggestion String The current suggestion shown. Read only.
suggestions [String] Array of suggestions.
suggestionType SuggestionType The type of suggestion that should be used. .Word will only hint the the next word in the suggestion and .Sentence will show the whole suggestion. Defaults to .Sentence.
pixelCorrections CGPoint Move the suggestion label up/down left/right. Use this to correct any differences if the suggestion doesn't match the input value for some reason.
horizontalPadding CGFloat Add padding to your textfield. Automatically set when using a borderStyle that has padding.
delimiter String Add a delimiter to only show a suggestion if there's more than one occurance of the delimiter. Perfect for autocompleting email providers.

  • Problem when resignFirstResponder is call

    Problem when resignFirstResponder is call

    Hi there!

    I'm facing a problem when I call self.view.endEditing(true), the autocomplete textField doesn't loose focus. I solved this behavior by changing your method (locally):

        public override func resignFirstResponder() -> Bool {
        self.label.text = nil
        super.resignFirstResponder() // add this line
        return true
    }

    I'm the right way? Thank you.

  • NSAttributedString range error

    NSAttributedString range error

    We should use NSString.length instead of String.count when dealing with NSRange and NSAttributedString. NSRange(location: 0, length: (labelText as NSString).length) is preferred to NSRange(location: 0, length:labelText.count). The error will occur when text is matching the suggestion "George😁Washington".
