获取某些CGPoint下的视图列表

Question

我需要获取某些CGPoint上的视图列表。使用此方法：

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

只给了我1个视图。有没有办法在该位置下获得一系列视图？

Answer 1

我认为你可以这样做：

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

point是您的[recognizer locationInView:recognizer.view]。当然，假设您在viewController中运行此代码。
