ios - Switch between UIScrollView -

-

i have 1 uiscrollview embedded in uiscrollview.

i switch first 1 other 1 when user scroll offset.

is there equivalent of [textfield becomefirstresponder], can use? instead of setting scrollview.scrollenabled = no , setting yes.

thanks

one strategy detect when want switch scroll views, animate 1 of them offscreen , other 1 on. example, scrollviewa being used , scrollviewb offscreen. when time comes switch scrollviewb onscreen , scrollviewa offscreen, use uianimation combined scrollingenabled.

- (void)timetoswitchscrollviews {     [uiview animatewithduration:5 animations: ^{         self.scrollviewa.frame = cgrectmake(/* somewhere off screen */);         self.scrollviewb.frame = cgrectmake(/* somewhere on  screen */);     }     completion: ^(bool finished) {         /* wait untill last minute turn of user interaction */         self.scrollviewa.scrollingenabled = no;     }       }
