UIKeyboardFrameChangedByUserInteractionkey 在键盘拆分时不会一直返回 1。
以下是UIKeyboardDidShowNotification / UIKeyboardDidHideNotification 上的完整用户信息字典键值。

UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {1024, 352}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {512, 944}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {512, 592}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{-352, 0}, {352, 1024}}";
UIKeyboardFrameChangedByUserInteraction = 0;
UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 0}, {352, 1024}}";
}
2012-07-11 11:52:45.675 Project[3856:707] keyboardDidHide: {
UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {1024, 352}}";
UIKeyboardCenterBeginUserInfoKey = "NSPoint: {512, 592}";
UIKeyboardCenterEndUserInfoKey = "NSPoint: {512, 944}";
UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 0}, {352, 1024}}";
UIKeyboardFrameChangedByUserInteraction = 0;
UIKeyboardFrameEndUserInfoKey = "NSRect: {{-352, 0}, {352, 1024}}";
}
相反,您可以使用UIKeyboardCenterBeginUserInfoKey 或UIKeyboardCenterEndUserInfoKey 键在键盘拆分时收到通知。
希望这会有所帮助!
