有文章http://blog.csdn.net/smilelance/article/details/7244759給出了正確的方向，不過照之實現，卻沒有實現相應的效果，可能是作者說的不明顯，也可以是我理解的太淺，這裏作一說明：
原文：
1、EAGLView.h裏面添加鍵盤類型屬性
@property(nonatomic) UIKeyboardType keyboardType;
2、CCEGLView_ios.mm 裏面添加對鍵盤設置的方法
//設置爲只有數字輸入法的鍵盤
void CCEGLView::setIMEKeyboardNumber()
{
EAGLView * view = [EAGLViewsharedEGLView];
view.keyboardType =UIKeyboardTypeNumberPad;
}
//設置爲默認的輸入法鍵盤
void CCEGLView::setIMEKeyboardDefault()
{
EAGLView * view = [EAGLViewsharedEGLView];
view.keyboardType =UIKeyboardTypePhonePad;
}
3、CCTextFieldTTF.h裏面添加自定義的輸入法鍵盤種類來做管理
enum eKeyBoardType{
KEY_BOARD_TYPE_NORMAL = 0,
KEY_BOARD_TYPE_NUMBER,
};
inline void setKeyboardType (eKeyBoardType type) {m_keyboardType = type; }
inline int getKeyboardType () {returnm_keyboardType; }
eKeyBoardType m_keyboardType;
4、bool CCTextFieldTTF::attachWithIME()改成這樣：
bool CCTextFieldTTF::attachWithIME()
{
bool bRet = CCIMEDelegate::attachWithIME();
if (bRet)
{
// open keyboard
CCEGLView * pGlView = CCDirector::sharedDirector()->getOpenGLView();
if (pGlView)
{
if (getKeyboardType() ==KEY_BOARD_TYPE_NORMAL) {
pGlView->setIMEKeyboardDefault();
}elseif (getKeyboardType() ==KEY_BOARD_TYPE_NUMBER) {
pGlView->setIMEKeyboardNumber();
}
pGlView->setIMEKeyboardState(true);
}
}
return bRet;
}
5、初始化用來輸入的CCTextFieldTTF的時候調用
setKeyboardType(KEY_BOARD_TYPE_NUMBER);來設置輸入法爲數字即可
6. 我的補充，在EAGLView中實現UITextInputTraits，即
-(UIKeyboardType) keyboardType
{
return keyboardType_;
}
-(void) setKeyboardType:(UIKeyboardType)keyboardType
{
keyboardType_ = keyboardType;
}
並在EAGLView.h添加屬性UIKeyboardType keyboardType_;
7.只有調用setKeyboardType 即可實現指定的鍵盤類型
