开发环境： Flash Builder 4.7
SDK： Flex 4.6.0 (build 23201) AIR 3.5
参数： -local en_US -swf-version=16
测试平台： iPad 2 上的 iOS 6

严重的错误，我相信。使使用这些技术开发的 iOS 应用程序完全无法使用。

情况：每当我在测试平台设备上触摸 TextInput 组件时，它会执行以下两种操作之一：

  1. 它将按预期执行。它获得焦点（调度了 focusIn 事件），围绕它的蓝色焦点矩形，提示文本被闪烁的光标替换，软键盘激活并显示（调度所有预期的事件）。
  2. 它会失败。它将获得焦点（调度focusIn事件），蓝色焦点矩形会短暂出现然后消失，提示文本保持显示并且字段中没有光标（调度focusOut事件）。调度 softKeyboardActivate 事件并立即调度 softKeyboardDeactivate 事件。键盘甚至没有短暂出现。

我可以轻敲轻敲，最终轻敲（与其他任何轻敲）都会成功，并且会发生＃1而不是＃2。

这是最奇怪的事情。focusManager 告诉我，在调度 focusIn 事件和调度 focusOut 事件后，具有焦点的 DisplayObject 是同一个对象（如果我使用计时器每 10 毫秒检查一次，结果不会改变......正确DO有重点。

代码下方是跟踪输出。
