iphone中附加日文键盘面板的UIKeyboardFrameEndUserInfoKey之类的常量是什么？

Question

什么是类似 UIKeyboardFrameEndUserInfoKey 的常量，用于 iphone/ipad 中的附加日语键盘面板？

[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[[userInfo objectForKey:UIKeyboardFrameEndUserInfoKey] getValue:&keyboardEndFrame];

Answer 1

常量是相同的 - UIKeyboardFrameEndUserInfoKey。但是- (void)keyboardWillShown:(NSNotification*)aNotification 事件上升了两次。
