获取某些CGPoint下的视图列表

Question

I need to get a list of views that are on certain CGPoint. Using this method:

- (void)handlePan:(UITapGestureRecognizer *)recognizer {
    UIView *subview = [recognizer.view hitTest:[recognizer locationInView:recognizer.view] withEvent:nil];
    //....
 }

gives me only 1 view. Is there any way to get an array of views under the location?

I think you can do something like this:

NSMutableArray *subviewsList = [NSMutableArray new];
for (UIView *subview in self.view.subviews) {
    if (CGRectContainsPoint(subview.frame, point) ) {
        [subviewsList addObject:subview];
    }
}

point is your [recognizer locationInView:recognizer.view] . Assuming, of course, you are running this code inside a viewController.
