+//  https://developers.google.com/+/terms
+//
+
+// To allow a user to share with Google+, please follow these steps:
+//
+// 0. Create a project on Google APIs console,
+//    https://code.google.com/apis/console . Under "API Access", create a
+//    client ID as "Installed application" with the type "iOS", and
+//    register the bundle ID of your application.
+//
+// 1. Initialize a GPPShare instance with your registered client ID:
+//
+//    GPPShare *gppShare = [[GPPShare alloc] initWithClientID:myClientID];
+//
+// 2. In the code where the share dialog is to be opened:
+//
+//    [[gppShare shareDialog] open];
+//
+//    You may optionally call |setURLToShare:| and/or |setPrefillText:| before
+//    calling |open|, if there is a particular URL resource to be shared, or
+//    you want to set text to prefill user comment in the share dialog, e.g.
+//
+//    NSURL *urlToShare = [NSURL URLWithString:@"http://www.google.com/"];
+//    NSString *prefillText = @"You probably already know this site...";
+//    [[[[gppShare shareDialog] setURLToShare:urlToShare]
+//        setPrefillText:prefillText] open];
+//
+// 3. In the 'YourApp-info.plist' settings for your application, add a URL
+//    type to be handled by your application. Make the URL scheme the same as
+//    the bundle ID of your application.
+//
+// 4. In your application delegate, implement
+//    - (BOOL)application:(NSString*)application
+//                openURL:(NSURL *)url
+//      sourceApplication:(NSString*)sourceApplication
+//             annotation:(id)annotation {
+//      if ([gppShare handleURL:url
+//            sourceApplication:sourceApplication
+//                   annotation:annotation]) {
+//        return YES;
+//      }
+//      // Other handling code here...
+//    }
+//
+// 5. Optionally, if you want to be notified of the result of the share action,
+//    have a delegate class implement |GPPShareDelegate|, e.g.
+//
+//    @interface MyDelegateClass : NSObject<GPPShareDelegate>;
+//
+//    - (void)finishedSharing:(BOOL)shared {
+//      // The share action was successful if |shared| is YES.
+//    }
+//
+//    MyDelegateClass *myDelegate = [[MyDelegateClass alloc] init];
+//    gppShare.delegate = myDelegate;
+
+#import <Foundation/Foundation.h>
+
+// Protocol to receive the result of the share action.
+@protocol GPPShareDelegate
+
+// Reports the status of the share action, |shared| is |YES| if user has
+// successfully shared her post, |NO| otherwise, e.g. user canceled the post.
+- (void)finishedSharing:(BOOL)shared;
+
+@end
+
+// The builder protocol to open the share dialog.
+@protocol GPPShareBuilder<NSCopying>
+
+// Sets the URL resource to be shared.
+- (id<GPPShareBuilder>)setURLToShare:(NSURL *)urlToShare;
+
+// Sets the text to prefill user comment in the share dialog.
+- (id<GPPShareBuilder>)setPrefillText:(NSString *)prefillText;
+
+// Sets the title, description, and thumbnail URL of the shared content preview
+// in the share dialog. Only set these fields if you are sharing with a content
+// deep link and don't have a URL resource. Title and description are required
+// fields.
+- (id<GPPShareBuilder>)setTitle:(NSString *)title
+                    description:(NSString *)description
+                   thumbnailURL:(NSURL *)thumbnailURL;
+
+// Sets the content deep-link ID that takes the user straight to your shared
+// content. Only set this field if you want the content deep-linking feature.
+// The content deep-link ID can either be a fully qualified URI, or URI path,
+// which can be up to 64 characters in length.
+- (id<GPPShareBuilder>)setContentDeepLinkID:(NSString *)contentDeepLinkID;
+
+// Opens the share dialog. Returns |NO| if there was an error, |YES| otherwise.
+- (BOOL)open;
+
+@end
+
+// The primary class for the share action on Google+.
+@interface GPPShare : NSObject
+
+// The object to be notified when the share action has finished.
+@property (nonatomic, assign) id<GPPShareDelegate> delegate;
+
+// All Google+ objects must be initialized with a client ID registered
+// in the Google APIs console, https://code.google.com/apis/console/
+// with their corresponding bundle ID before they can be used.
+- (id)initWithClientID:(NSString *)clientID;
+
+// Returns a share dialog builder instance. Call its |open| method to
+// create the dialog after setting the parameters as needed.
+- (id<GPPShareBuilder>)shareDialog;
+
+// This method should be called from your |UIApplicationDelegate|'s
+// |application:openURL:sourceApplication:annotation|. Returns |YES| if
+// |GPPShare| handled this URL.
+- (BOOL)handleURL:(NSURL *)url
+    sourceApplication:(NSString *)sourceApplication
+           annotation:(id)annotation;
