为cocos2d-x 添加启动数字输入法的功能
有文章http://blog.csdn.net/smilelance/article/details/7244759给出了正确的方向，不过照之实现，却没有实现相应的效果，可能是作者说的不明显，也可以是我理解的太浅，这里作一说明：
原文：
1、EAGLView.h里面添加键盘类型属性
@property(nonatomic) UIKeyboardType keyboardType;
2、CCEGLView_ios.mm 里面添加对键盘设置的方法
//设置为只有数字输入法的键盘
void CCEGLView::setIMEKeyboardNumber()
{
EAGLView * view = [EAGLViewsharedEGLView];
view.keyboardType =UIKeyboardTypeNumberPad;
}
//设置为默认的输入法键盘
void CCEGLView::setIMEKeyboardDefault()
{
EAGLView * view = [EAGLViewsharedEGLView];
view.keyboardType =UIKeyboardTypePhonePad;
}
3、CCTextFieldTTF.h里面添加自定义的输入法键盘种类来做管理
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()改成这样：
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、初始化用来输入的CCTextFieldTTF的时候调用
setKeyboardType(KEY_BOARD_TYPE_NUMBER);来设置输入法为数字即可
6. 我的补充，在EAGLView中实现UITextInputTraits，即
-(UIKeyboardType) keyboardType
{
return keyboardType_;
}
-(void) setKeyboardType:(UIKeyboardType)keyboardType
{
keyboardType_ = keyboardType;
}
并在EAGLView.h添加属性UIKeyboardType keyboardType_;
7.只有调用setKeyboardType 即可实现指定的键盘类型
