iphone - 获取某个CGPoint下的 View 列表

Question

我需要获取某个 CGPoint 上的 View 列表。使用此方法:

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

只给我 1 个 View 。有什么办法可以得到location下的view数组吗？

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。
