swiftで、現在地を取得して、GoogleMapで表示

More than 1 year has passed since last update.

swiftで喫茶店探しのアプリを作る過程で
現在地を取得して、GoogleMapで表示できましたので、ソース公開します
https://github.com/shiratsu/NeoCafedagashiForSwift

詳しい解説は省略します(そのうち書きます)

余計なソースも混じってますが、開発中ですのでご容赦ください

まずは、CocoaPodsで、使うライブラリ読み込み

Podfile
➜  NeoCafeSagashiForSwift git:(master) ✗ cat Podfile
platform :ios, '7.0'

pod 'Google-Maps-iOS-SDK', '~> 1.8.1'
pod 'SMCalloutView', '~> 2.0'
pod 'SVProgressHUD'
pod 'AFNetworking'

CocoaPodsのファイルが出来ると、多分勝手に作られたような気がするけど、Bridging-Header.hファイルに、読み込むobjective-Cのライブラリ読み込み

Bridging-Header.h
#import <GoogleMaps/GoogleMaps.h>
#import <SMCalloutView/SMCalloutView.h>
#import "GADBannerView.h"
#import "GoogleMapAPIKey.h"

上に書けば使えるのでどこかでimportとか要らないです
*もし読み込めてなかったら、以下を参考にやってみてね

また、CoreLocation.Frameworkの追加を忘れずに
*mapviewはstoryboardでViewControllerに定義してある、mapviewと紐付けています

                abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.

                Typical reasons for an error here include:
                * The persistent store is not accessible;
                * The schema for the persistent store is incompatible with current managed object model.
                Check the error message to determine what the actual problem was.


                If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.

                If you encounter schema incompatibility errors during development, you can reduce their frequency by:
                * Simply deleting the existing store:
                NSFileManager.defaultManager().removeItemAtURL(storeURL, error: nil)

                * Performing automatic lightweight migration by passing the following dictionary as the options parameter:
                [NSMigratePersistentStoresAutomaticallyOption: true, NSInferMappingModelAutomaticallyOption: true}

                Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.
