I want to be able to make a gesture recognizer listening for a two finger swipe, anywhere on the screen.
Right now I have a UITableView in a sub-view that scrolls, of course, and it doesn’t seem to pick up the UIGestureRecognizer that I set on the view. When you use the two fingers, it just scrolls…
Is there a way to make the entire view, maybe superview, listen for a two finger touch and when it recognizes it, it will instead of scrolling the table view, do what I want it to do?
EDIT: Heres my code but this is suposed to be a very general question. I just want to be able to have UIGestureRecognizers across the entire view, the whole thing.
navBarTitle.title = @"Crunch";
//opening the menuView from launch
//setup the customtable view as a subview in menuView
SDMenuViewController *mvc = [[[SDMenuViewController alloc] initWithNibName:@"SDNestedTableView" bundle:nil] autorelease];
[self addChildViewController:mvc];
[mvc didMoveToParentViewController:self];
[menuView addSubview:mvc.view];
[mvc.view setFrame:CGRectMake(mvc.view.frame.origin.x, mvc.view.frame.origin.y, mvc.view.frame.size.width, mvc.view.frame.size.height + 44)]; //add navBarHeight, for some strage reason
//add swipe down gesture on for the menu
UISwipeGestureRecognizer *swipeClose =[[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(closeMenu)] autorelease];
swipeClose.numberOfTouchesRequired = 2;
swipeClose.direction = UISwipeGestureRecognizerDirectionUp;
UISwipeGestureRecognizer *swipeOpen = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(openMenu)] autorelease];
swipeOpen.numberOfTouchesRequired = 2;
swipeOpen.direction = UISwipeGestureRecognizerDirectionDown;
for (UIGestureRecognizer* rec in menuView.gestureRecognizers) {
[rec requireGestureRecognizerToFail:swipeClose];
[rec requireGestureRecognizerToFail:swipeOpen];
}
for (UIGestureRecognizer* rec in mvc.view.gestureRecognizers) {
[rec requireGestureRecognizerToFail:swipeClose];
[rec requireGestureRecognizerToFail:swipeOpen];
}
[mvc.view addGestureRecognizer:swipeClose];
[mvc.view addGestureRecognizer:swipeOpen];
[self.view addGestureRecognizer:swipeClose];
[self.view addGestureRecognizer:swipeOpen];
Maybe I did not explain my question clearly. But for what I was doing this ended up working, and maybe it will help other people in the future:
