CocoaPod version not up to date with demo

[JamaicanRumCream]

The Cocoapod version (ObjC) of the last release is not up to date with the demo app. Specifically in GCM.h file:

/// DEPRECATED. Use presentLeaderboardsOnViewController: withLeaderboard: instead.
- (void)presentLeaderboardsOnViewController:(UIViewController *)viewController __deprecated;

/// Presents the GameCenter Leaderboards ViewController with Leaderboard Identifier over the specified ViewController. Dismissal and delegation is handled by GameCenterManager.
- (void)presentLeaderboardsOnViewController:(UIViewController *)viewController withLeaderboard:(NSString *)leaderboard;

In Cocoapods version this deprecation and new method is not there.
