【COCOS2DX-游戏开发之八】点击空白隐藏键盘

http://blog.csdn.net/teng_ontheway/article/details/9162781

cocos2dx edit编辑框点击后显示一个键盘，但是非常的不灵活，点return才能隐藏，如果我们需要点键盘外的背景，实现隐藏键盘，那就方便多了

1. 到EGLView.mm下注释2个reurn，这样就能保证显示软键盘的时候，还能将点击事件传送到最底层

[cpp] view plaincopy

//Passthetouchestothesuperview@H_502_50@
#pragmamarkEAGLView-TouchDelegate@H_502_50@
-(void)touchesBegan:(NSSet*)toucheswithEvent:(UIEvent*)event@H_502_50@
{@H_502_50@
if(isKeyboardShown_)@H_502_50@
{@H_502_50@

floatxs[IOS_MAX_TOUCHES_COUNT]={0.0f};@H_502_50@
floatys[IOS_MAX_TOUCHES_COUNT]={0.0f};@H_502_50@
@H_502_50@

for(UITouch*touchintouches){@H_502_50@
ids[i]=(int)touch;@H_502_50@

ys[i]=[touchlocationInView:[touchview]].y*view.contentScaleFactor;;@H_502_50@
++i;@H_502_50@
}@H_502_50@
cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesBegin(i,ids,xs,ys);@H_502_50@
}@H_502_50@

[cpp] view plaincopy

-(void)touchesEnded:(NSSet*)toucheswithEvent:(UIEvent*)event@H_502_50@
{@H_502_50@

@H_502_50@

}@H_502_50@
cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesEnd(i,ys);@H_502_50@
}@H_502_50@

2.最底层的layer类中添加处理：显示和隐藏键盘就OK了

[cpp] view plaincopy

voidccTouchEnded(cocos2d::CCTouch*pTouch,cocos2d::CCEvent*pEvent)@H_502_50@
{@H_502_50@
do@H_502_50@
{@H_502_50@
if(mTelNumber){@H_502_50@
CCPointendPos=pTouch->getLocation();@H_502_50@
@H_502_50@
floatdelta=5.f;@H_502_50@
if(::abs(mBeginPos.x-endPos.x)>delta@H_502_50@
||::abs(mBeginPos.y-endPos.y)>delta){@H_502_50@
break;@H_502_50@
}@H_502_50@
@H_502_50@
//看编辑框是否被点中@H_502_50@
CCPointpoint=mTelNumber->getParent()->convertTouchToNodeSpaceAR(pTouch);@H_502_50@
@H_502_50@
//锚点(0.f,0.5f)@H_502_50@
//intx=mTextField->getParent()->getPosition().x;@H_502_50@
//inty=mTextField->getParent()->getPosition().y;@H_502_50@
intw=mTelNumber->getContentSize().width;@H_502_50@
inth=mTelNumber->getContentSize().height;@H_502_50@
CCRectrect=CCRect(0,-h/2,w,h);@H_502_50@
@H_502_50@
onClickedTextField(rect.containsPoint(point));@H_502_50@
}@H_502_50@
}while(0);@H_502_50@
@H_502_50@
DialogLayer::ccTouchEnded(pTouch,pEvent);@H_502_50@
}@H_502_50@
@H_502_50@
/**点击推广码输入框*/@H_502_50@
voidonClickedTextField(boolb)@H_502_50@
{@H_502_50@
if(b){@H_502_50@
mTelNumber->attachWithIME();@H_502_50@
}else{@H_502_50@
mTelNumber->detachWithIME();@H_502_50@
}@H_502_50@
