iOS 11 - motionBegan not being called on FBTweakShakeWindow

[joelmarquez90]

After upgrading iOS to Beta 11 (15A5328g), the - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event method on FBTweakShakeWindow is never called.

i find this issue too on iOS 11.0 (15A5327g) .but i think this is apple's problem .

and i found that we can use AssistiveTouch to simulate a shake to invoke the - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event method .
