objective c: detect touch began/down when touch started from outside of view/image/button -

-

i have resembles key pad (one master view, 9 subviews). touch began/down may start in of 9 subviews. detect touch down/began, know when user drags finger other subviews (which views finger dragged into), , when user lifts finger up/touch up/stop.

(stack overflow not letting question posted. i'll try pasting code answer section, see if works).

// in ib set long press gesture min duration 0.1 -(ibaction)handlelongpressonvoices:(uilongpressgesturerecognizer *)gesturerecognizer     {         cgpoint location = [gesturerecognizer locationinview:gesturerecognizer.view];      if (gesturerecognizer.state == uigesturerecognizerstatebegan){         [self whichvoiceselected:location];     } else if(gesturerecognizer.state == uigesturerecognizerstatechanged){         [self whichvoiceselected:location];     } else if(gesturerecognizer.state == uigesturerecognizerstateended){         [self.avplayer stop];     } }

-(void)whichvoiceselected:(cgpoint)location {

int updatedselectedvoicenumber;  if(cgrectcontainspoint(self.voice0.frame, location)){     updatedselectedvoicenumber=0;     self.statuslabeloutlet.text = @"..."; }else if(cgrectcontainspoint(self.voice1.frame, location)){     updatedselectedvoicenumber=1;     self.statuslabeloutlet.text = @"..."; }else if(cgrectcontainspoint(self.voice2.frame, location)){     updatedselectedvoicenumber=2;     self.statuslabeloutlet.text = @"..."; } ...

... }

i found parts of answer across many stackoverflow replies. pasting approach resolving question (a) next person , (b) invitation better solutions.
