GooglePlacesRow is a row extension for Eureka. It implements a row where the user can use Google Places autocomplete functionality to select a place suggested by the API.

GooglePlacesRow includes two rows with similar functionality but their options are displayed diferently:

• GooglePlacesAccessoryRow: displays a collection view as the inputAccessoryView of the cell. The user will be able to scroll horizontally to select the desired place
• GooglePlacesTableRow: displays a UITableView directly below the cell for the user to choose the desired option.

The project is experimental and open to changes although it is already quite customizable.

Please follow the installation instructions

// in AppDelegate.swift
import GoogleMaps

// then in application:didFinishLaunchingWithOptions:
let apiKey = "YOUR_API_KEY"
GMSServices.provideAPIKey(apiKey)


//in your subclass of FormViewController
form +++ Section("Choose from table view")
            <<< GooglePlacesTableRow()
     +++ Section("Customized cell, customized layout")
         <<< GooglePlacesAccessoryRow().cellSetup { cell, row in
             (cell.collectionViewLayout  as? UICollectionViewFlowLayout)?.sectionInset = UIEdgeInsetsZero
             (cell.collectionViewLayout  as? UICollectionViewFlowLayout)?.minimumInteritemSpacing = 40
             cell.customizeCollectionViewCell = { cvcell in
                 cvcell.label.textColor = UIColor.redColor()
                 cvcell.layer.borderColor = UIColor.redColor().CGColor
                 cvcell.layer.borderWidth = 1
                 cvcell.layer.cornerRadius = 4
                 }
        }

To see what you can customize have a look at the Customization section or the FAQ

• Eureka (obviously)
• GooglePlaces (and all the frameworks it depends on)
• GoogleMapsBase

• iOS 8.0+
• Xcode 8.3+

Follow these steps to run Example project:

• Clone GooglePlacesRow repository
• Run carthage update in the root of the project
• Open GooglePlacesRow workspace
• Set your Google places API KEY in AppDelegate.swift
• and run the Example project.

Follow these steps to run Example project:

• Clone GooglePlacesRow repository
• Execute git submodule add https://github.com/xmartlabs/Eureka.git in the cloned folder.
• Open GooglePlacesRow workspace
• Set your Google places API KEY in AppDelegate.swift
• and run the Example project.

CocoaPods is a dependency manager for Cocoa projects.

To install GooglePlacesRow, simply add the following line to your Podfile:

pod 'GooglePlacesRow'

This will also install Eureka and GooglePlaces.

Note: Do not add pod 'GooglePlaces' to your podfile as this library includes it as a vendored framework

There are five variables that you can use to modify the default behaviour of these rows:

• In the row:
  • placeFilter: Is a GMSAutocompleteFilter used in the request to Google Places to define what kind of suggestions will be returned (e.g. cities, addresses, country). Refer to the official docummentation of Google for more detailed information.
  • placeBounds: Bounds to limit the search for places. Refer to the official docummentation of Google for more detailed information.
  • onNetworkingError: Block that is called when the request to Google Places returns an error
• In the cell:
  • useTimer: If the request to Google Places should be throttled using a timer. If true then it will wait for timerInterval seconds before making a request. If the user continues entering text into the row then the previous request will not be fired
  • timerInterval: The interval in seconds used for the timer explained above

GooglePlacesAccessoryRow uses a generic GooglePlacesCollectionCell cell whose generic parameter is the UICollectionViewCell class used in the inputAccessoryView.

• If you just want to change minor things of the cell (you most probably will want to) then the customizeCollectionViewCell callback is for you. This block is called in the delegates collectionView:cellForItemAtIndexPath: method.

• If you want to change the layout of the collectionView then you can use/modify/override the collectionViewLayout attribute in the cellSetup method when declaring the row. Have a look at the examples for this.

• If you want to change something about the collectionView (e.g. its height, backgroundColor) then you can also do that in the cellSetup method. Have a look at the examples for this.

• If you want to change the collection view cell of the inputAccessoryView drastically then there is nothing easier than creating your own row (MyGooglePlacesAccessoryRow) with your own MyCollectionViewCell:

public final class MyGooglePlacesAccessoryRow: _GooglePlacesRow<GooglePlacesCollectionCell<MyCollectionViewCell>>, RowType {
    required public init(tag: String?) {
        super.init(tag: tag)
    }
}

In this case just make sure your cell conforms to EurekaGooglePlacesCollectionViewCell

GooglePlacesTableRow uses a generic GooglePlacesTableCell cell whose generic parameter is the UITableViewCell class used to create the cells displayed in a UITableView with the suggested options from Google Places.

• If you just want to change minor things of the cells that display the options (you will most probably want to) then the customizeTableViewCell callback is for you. This block is called in the delegates tableView:cellForRowAtIndexPath: method.

• You can customize attributes of the tableView that is displayed with the options. You should do this in cellSetup and keep in mind that the frame of the tableView is reset each time the tableView is displayed.

• If you want to change these cells drastically then there is nothing easier than creating your own row (MyGooglePlacesAccessoryRow) with your own MyCollectionViewCell:

public final class MyGooglePlacesAccessoryRow: _GooglePlacesRow<GooglePlacesCollectionCell<MyCollectionViewCell>>, RowType {
    required public init(tag: String?) {
        super.init(tag: tag)
    }
}

In this case just make sure your cell conforms to EurekaGooglePlacesTableViewCell

This is most probably because you forgot to tell Xcode where GoogleMapsBase.framework or GooglePlaces.framework is or you did forget to download it altogether. Please follow the example instructions or the installation instructions.

• Carthage compatibility
• Investigate automation of the installation process
