A GCGamepadSnapshot snapshot is a concrete GCGamepad implementation. It can be used directly in an
|
|
application to implement controller input replays. It is also returned as the result of polling
|
|
a controller.
|
|
|
|
The current snapshotData is readily available to access as NSData. A developer can serialize this to any
|
|
destination necessary using the NSData API.
|
|
|
|
The data contains some version of a GCGamepadSnapShotData structure.
