cocos2d-objc v3.4.9 CCScrollView problems after migrating to Xcode7, iOS9

After updating cocos2d-objc project to Xcode7, iOS9 I have got my CCScrollView instances broken. Tap and pan gestures aren't recognized + xcode throws console warning

WARNING: A Gesture recognizer (; target= <(action=handleTap:, target=)>>) was setup in a storyboard/xib to be added to more than one view (->; layer = >) at a time, this was never allowed, and is now enforced. Beginning with iOS 9.0 it will be put in the first view it is loaded into.

Problem had been fixed after patching CCScrollView and using UIView's api to manipulate current gestureRecoznigers list with corresponding API methods

-addGestureRecognizer: -removeGestureRecognizer:

- (void) onEnterTransitionDidFinish
{
    // Add recognizers to view
    UIView* view = [CCDirector sharedDirector].view;

    /*
    NSMutableArray* recognizers = [view.gestureRecognizers mutableCopy];
    if (!recognizers) recognizers = [NSMutableArray arrayWithCapacity:2];
    [recognizers insertObject:_panRecognizer atIndex:0];
    [recognizers insertObject:_tapRecognizer atIndex:0];

    view.gestureRecognizers = recognizers;
     */
    [view addGestureRecognizer:_panRecognizer];
    [view addGestureRecognizer:_tapRecognizer];

    [super onEnterTransitionDidFinish];
}

- (void) onExitTransitionDidStart
{
    // Remove recognizers from view
    UIView* view = [CCDirector sharedDirector].view;

    /*NSMutableArray* recognizers = [view.gestureRecognizers mutableCopy];
    [recognizers removeObject:_panRecognizer];
    [recognizers removeObject:_tapRecognizer];

    view.gestureRecognizers = recognizers;*/
    [view removeGestureRecognizer:_panRecognizer];
    [view removeGestureRecognizer:_tapRecognizer];

    [super onExitTransitionDidStart];
}
