无法从没有窗口的视图中呈现弹出窗口 [英] Popovers cannot be presented from a view which does not have a window

问题描述

此错误表示：

"Popovers cannot be presented from a view which does not have a window."

推荐答案

您要添加popover的视图必须已添加到窗口使用addSubview：方法。

the view you're adding the popover to has to already have been added to a window with the "addSubview:" method.

尝试等待

- (void) didMoveToWindow

为视图调用

然后加载popover

is called for the view and then load the popover
