次のコード（長さは申し訳ありません）には、iOS 4.3の下で奇妙な動作が表示されます（他のバージョンも）。この例には、3つあります UITextField3つの異なるサイズのキーボードがあるs。 1つのテキストフィールドの編集を開始してから、キーボードを却下する「戻り」にタッチすると、キーボードのサイズが正しく返されるたびに UIKeyboardWillShowNotification と UIKeyboardDidShowNotification 使用 UIKeyboardFrameBeginUserInfoKey.
下記参照：
- (void) keyboardWillShowNotification:(NSNotification *)aNotification
と
- (void) keyboardDidShowNotification:(NSNotification *)aNotification
これが予想される動作であることに注意してください。
action reported keyboard size expected keyboard size
--------------------- ---------------------- ----------------------
touch one & return 100 100
touch two & return 200 200
touch normal & return 216 216
n & return keyboard size(n) keyboard size(n)
予期しない動作は、テキストフィールドの編集を開始した場合、最初のキーボードのサイズが報告されています（予想）。 2番目のテキストフィールドに触れると（触れても触れずに）、最初のキーボードのサイズが報告されます（予期しない）2番目のキーボードは報告されます（予期しない）。 3番目のテキストフィールドに触れると（触れても触れずに）、2番目のキーボードサイズのサイズが3番目のサイズではなく（予期しない）報告されます。 2番目からn番目に、表示されるキーボードのサイズではなく、以前のキーボードのサイズを報告しているようです。
action reported keyboard size expected keyboard size
------------ ---------------------- ----------------------
touch one 100 100
touch two 100 200
touch normal 200 216
touch one 216 100
n keyboard size(n-1) keyboard size(n)
バグレポートを送信する前に、私は何も見すぎていないことを確認したいだけです。
参考までに、私は正しいことをしようとしている間にこれに根を下げました（使用して UIKeyboardWillShowNotification また UIKeyboardDidShowNotification と UIKeyboardFrameBeginUserInfoKey キーボードのサイズを取得するには）ビューをシフトして、キーボードによって不明瞭になっていたテキストフィールドが表示されるようにします。参照：
キーボードが存在するときにuitextfieldを上に移動させる方法は？

解決
で報告されているように この質問, 、 start frame （キー付き UIKeyboardFrameBeginUserInfoKey）キーボードがある場所です 始まり アニメーションの。 UIKeyboardFrameEndUserInfoKey あなたを手に入れるべきです end frame 代わりは。おそらく、サイズもフレーム間で異なるでしょう。
