mais ce code fonctionne dans iphone sdk 3.0, mais ce code ne fonctionne pas dans le SDK de l'iPhone 4.0 il est dit que la clé d'information de l'utilisateur de rebond uikeyboard dépréciée dans l'iPhone OS 4.0 ne crée pas la barre d'outils par DONE bouton s'il vous plaît me guider comment pourrais-je faireUIKeyboardBoundsUserInfoKey dépréciée dans l'iPhone OS 4.0
