Simple iOS and Mac OS X feature manager for unlocking functionality (e.g. for IAP purchases).

Usage

Unlock a feature (all features are locked by default):

[GBFeatureManager unlockFeature:@"speedBoost"];

Lock a feature:

[GBFeatureManager lockFeature:@"speedBoost"];

Check to see if a feature is unlocked:

[GBFeatureManager isFeatureUnlocked:@"speedBoost"];		//Returns: YES or NO

If you want to unlock all features + any future features, think of it as an "all features unlocked override" (N.B. this will supersede any individual setting):

[GBFeatureManager enableWildcardFeatureOverride];

To turn off the "all features unlocked override":

[GBFeatureManager disableWildcardFeatureOverride];

To enabled features by default (e.g. Pro version), you can unlock some features directly in the Info.plist by adding it as a key to the Plist, prefixed by GBFeatureManager: and setting the value to a Boolean.

<key>GBFeatureManager:com.goonbee.proVersion</key>
<true/>

...normally you would do this in Xcode's Plist editor by simply adding a new row with the key GBFeatureManager:com.goonbee.proVersion, setting the type to Boolean and the value to either YES or NO.

Don't forget to import header, for iOS:

#import "GBFeatureManager.h"

... or on OSX:

#import <GBFeatureManager/GBFeatureManager.h>

Storage mechanics

Features are each stored to disk in simple serialized NSNumber objects to the NSDocumentsDirectory on iOS, or NSApplicationSupportDirectory OS X.

When checking whether a feature is available, the disk is only accessed the first time, and the result is cached in memory, subsequent checks never hit the disk.

Dependencies

iOS: Add to your project's workspace, add dependency for GBToolbox-iOS and GBStorageController-iOS, link with your binary, add -ObjC linker flag, add header search path.

OS X: Add to your project's workspace, add dependency for GBToolbox-OSX and GBStorageController-OSX, link with your binary, add "copy file" step to copy framework into bundle.
