GooglePlacesAutocomplete

A simple Google Places API autocompleting address entry view for iOS devices.

There are already a couple of solutions out there for this. GooglePlacesAutocomplete is different because it is 100% Swift, and aims to provide the simplest possible method of entering validated, autocompleted addresses.

No attempt has been made to integrate MapKit since displaying Google Places on a non-Google map is against their terms of service.

Requirements

• iOS 7.0+
• XCode 7.0+ / Swift 2.0

Installation

Embedded frameworks require a minimum deployment target of iOS 8.

To use GooglePlacesAutocomplete with a project targeting iOS 7, you must include the source files directly in your project. See the 'manual installation' section for instructions.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ gem install cocoapods

To integrate GooglePlacesAutocomplete into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'

pod 'GooglePlacesAutocomplete'

Then, run the following command:

$ pod install

Manual

Simply copy GooglePlacesAutocomplete.swift and GooglePlacesAutocomplete.xib to your project.

Note: Don't forget to add the PoweredByGoogle image to your xcassets.

Usage

Use the Google Developers Console to enabled the 'Google Places API Web Service' and create a 'Server' API key credential. In both cases do not use the iOS options.

import GooglePlacesAutocomplete // Not required when including source files directly in project

let gpaViewController = GooglePlacesAutocomplete(
  apiKey: "[YOUR GOOGLE PLACES API KEY]",
  placeType: .Address
)

gpaViewController.placeDelegate = self // Conforms to GooglePlacesAutocompleteDelegate

presentViewController(gpaViewController, animated: true, completion: nil)

GooglePlacesAutocompleteDelegate supports three methods:

• placesFound(places: [Place]): Invoked whenever the Google Places API is called
• placeSelected(place: Place): Invoked when a new place is selected
• placeViewClosed(): Invoked when the view is closed

Here's a complete example.

Place Details

From Google's documentation: "you can request more details about a particular establishment or point of interest by initiating a Place Details request. A Place Details request returns more comprehensive information about the indicated place such as its complete address, phone number, user rating and reviews."

place.getDetails { details in
  println(details.name)       // Convenience accessor for name
  println(details.latitude)   // Convenience accessor for latitude
  println(details.longitude)  // Convenience accessor for longitude
  println(details.raw)        // Complete JSON data (see below)
}

/*
  [
    status: OK,
    result: {
      "address_components" = (
        {
          "long_name" = Paris;
          "short_name" = Paris;
          types = (
            locality,
            political
          );
        },
        ...
      );
      geometry = {
        location = {
          lat = "48.856614";
          lng = "2.3522219";
        };
  ...
*/

See the documentation for full response details.

Location Biasing

The Place Autocomplete API supports biasing results to a specified circle by passing a location and a radius parameter. This instructs the service to prefer showing results within that circle. Results outside of the defined area may still be displayed.

gpaViewController.locationBias = LocationBias(latitude: 48.8534275, longitude: 2.3582787999999937, radius: 1000)

Styling

The UINavigationController appearance can also easily be changed, for example:

gpaViewController.navigationBar.barStyle = UIBarStyle.Black
gpaViewController.navigationBar.translucent = false
gpaViewController.navigationBar.barTintColor = UIColor(red: 0.11, green: 0.27, blue: 0.53, alpha: 1.0)
gpaViewController.navigationBar.tintColor = UIColor.whiteColor()
gpaViewController.navigationBar.titleTextAttributes = [NSFontAttributeName: UIFont(name: "Zapfino", size: 16.0)!]

Also, to change the contents of the title bar:

gpaViewController.navigationItem.title = "Enter City"
gpaViewController.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Cancel, target: gpaViewController, action: "close")
