The final Swift 2 version is 0.2.5. 15 | 16 | To run the example project, clone the repo, and run `pod install` from the Example directory first. 17 | 18 | In addition to turning on the 'Maps' capability, you'll need to add `location-services` to `UIRequiredDeviceCapabilities`and fill in `NSLocationAlwaysUsageDescription` in your Info.plist. 19 | 20 | Other than that just set up the view controller and implement the delegate method: 21 | 22 | ```swift 23 | // ... 24 | let mapViewController = MapViewController(nibName: "MapViewController", bundle: MapViewController.bundle) 25 | mapViewController.delegate = self 26 | mapViewController.selectedMapItem = self.selectedMapItem // Optional. 27 | // ... 28 | 29 | func mapViewController(_ mapViewController: MapViewController, didSelectMapItem mapItem: MKMapItem) { 30 | self.selectedMapItem = mapItem // Save, submit, etc. 31 | mapViewController.dismissViewController(animated: true, completion: nil) 32 | } 33 | ``` 34 | 35 | See [example app](//github.com/hlfcoding/HLFMapViewController/blob/master/Example/HLFMapViewController/ViewController.swift) for more details. 36 | 37 | ## Installation 38 | 39 | HLFMapViewController is available through [CocoaPods](http://cocoapods.org). To install 40 | it, simply add the following line to your Podfile: 41 | 42 | ```ruby 43 | pod "HLFMapViewController" 44 | ``` 45 | 46 | ## License 47 | 48 | HLFMapViewController is available under the MIT license.
