UIWINDOW 子视图上的 UIAccessibility

Question

您好，已将 Viewcontroller 视图添加到 UIWINDOWS 中，如下所示

[[[UIApplication sharedApplication] keyWindow] addSubview:self.myviewcontroller.view];

但现在 myviewcontroller 视图的 UIAccessibility 不起作用。它得到了那个 window.

的任何背面

Answer 1

我想出了解决办法，我们应该在最顶层添加子视图 window.

        UIWindow* window = [UIApplication sharedApplication].keyWindow;
    if (!window)
        window = [[UIApplication sharedApplication].windows objectAtIndex:0];
    [[[window subviews] objectAtIndex:0] addSubview:self.myviewController.view];
