I’m using Core Plot to display a scatter plot graph, and I’d like to use a swipe gesture to switch between the graph itself and a UITableView of the data the graph is made up of. My UISwipeGestureRecognizer is working fine on the table view, but the swipe events are not triggered on the graph. The graph is a UIView with class set to CPTGraphHostingView, and my code is as follows :

UISwipeGestureRecognizer *swipeRight = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(swipeHistoryData:)];
[swipeRight setDirection:UISwipeGestureRecognizerDirectionRight];
[graphHostingView addGestureRecognizer:swipeRight];
[tableListView addGestureRecognizer:swipeRight];

My guess is that the CPTGraphHostingView is ‘eating’ the swipes in some way so they are not detected by my recognizer. Can anybody comment or put me on the right road?

    Sorry just figured it out – I was adding the same gesture recognizer to both the graph view and the table view. I always forget this doesn’t work – because the it was added to the table view after the graph view, only the table view receives the events. I need to use 2 gesture recognizers (unless somebody can tell me different).
