ios - Detecting shake gesture by multiple view controllers -

-

i need detect shake gesture in ios. have done usual stuff , works fine. thing have multiple view controllers in uitabbarcontroller , wish each of them detect shake gesture.

when shaking in of view controller , switched particular tab. problem if shake in 1 view controller , try shake in other controller gesture not detected unless action performed in controller.

i know need set becomefirstresponder need know how can property set current tab of uitabbarcontroller shake gesture recognised tabs.

write code detection (usually via notification observer shake) in base view controller , and controller subclass this. can write code move particular tab in base controller.

problem solved.
