全屏弹出且可阻塞的选取视图。

控制 gif 视频（不够清晰，最好试试示例 :)）

问题

在我的一个工作项目中，我需要在 UITableViewController 的 tableView 中显示一个选取视图，所以我将选取视图作为 tableView 的子视图添加。结果是这个选取视图将与 tableView 一起滚动。

如何解决这个问题

我们需要一个类似于模态和阻止动作的控件，所以这里出现了 UIActionSheet。我们必须自定义 UIActionSheet 以显示选取视图。

众所周知，UIActionSheet 不能拖入一个空的 xib，但是 UIView 可以。所以我们从一个 UIView 开始，并进行布局，然后将 UIView 的类名改为 UIActionSheet。这对于一些基于 UIView 的控件是可行的。

使其可弹出

使用 pop。

使其可阻塞

提供一个新方法 showInView，并且千万不要忘记调用 [super showInView:view]

- (void)showInView:(UIView *)view doneEvent:(ActionEvent)doneEvent cancelEvent:(ActionEvent)cancelEvent
{
    self.cancel.click = ^(id sender) {
        if (cancelEvent) {
            cancelEvent(self);
        }
        [self dismiss];
    };
    self.done.click = ^(id sender) {
        if (doneEvent) {
            doneEvent(self);
        }
        [self dismiss];
    };
[super showInView:view];
}
