cocos2d-x 添加启动数字输入法的功能

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. 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_;

我得补充：如果在 EAGLView中没有添加@property(nonatomic)UIKeyboardTypekeyboardType;的话，程序会在

view.keyboardType = UIKeyboardTypeASCIICapable 的时候崩溃，报错：unrecognized selector sent to instance。

7.只有调用setKeyboardType 即可实现指定的键盘类型
