【COCOS2DX-游戏开发之八】点击空白隐藏键盘

cocos2dx隐藏键盘点击空白隐藏键盘

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

方法：

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

1. //Passthetouchestothesuperview
2. #pragmamarkEAGLView-TouchDelegate
3. -(void)touchesBegan:(NSSet*)toucheswithEvent:(UIEvent*)event
4. {
5. if(isKeyboardShown_)
6. {
7. [selfhandleTouchesAfterKeyboardShow];
9. //WARNING:commentedbyTeng.点触背景隐藏软键盘
10. //return;
11. }
13. intids[IOS_MAX_TOUCHES_COUNT]={0};
14. floatxs[IOS_MAX_TOUCHES_COUNT]={0.0f};
15. floatys[IOS_MAX_TOUCHES_COUNT]={0.0f};
17. inti=0;
18. for(UITouch*touchintouches){
19. ids[i]=(int)touch;
20. xs[i]=[touchlocationInView:[touchview]].x*view.contentScaleFactor;;
21. ys[i]=[touchlocationInView:[touchview]].y*view.contentScaleFactor;;
22. ++i;
23. }
24. cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesBegin(i,ids,xs,ys);
25. }

[cpp] view plaincopy

1. -(void)touchesEnded:(NSSet*)toucheswithEvent:(UIEvent*)event
2. {
3. if(isKeyboardShown_)
4. {
5. <strong><spanstyle="color:#ff0000;">//WARNING:commentedbyTeng.点触背景隐藏软键盘</span>
6. //return;</strong>
7. }
9. intids[IOS_MAX_TOUCHES_COUNT]={0};
10. floatxs[IOS_MAX_TOUCHES_COUNT]={0.0f};
11. floatys[IOS_MAX_TOUCHES_COUNT]={0.0f};
13. inti=0;
14. for(UITouch*touchintouches){
15. ids[i]=(int)touch;
16. xs[i]=[touchlocationInView:[touchview]].x*view.contentScaleFactor;;
17. ys[i]=[touchlocationInView:[touchview]].y*view.contentScaleFactor;;
18. ++i;
19. }
20. cocos2d::CCEGLView::sharedOpenGLView()->handleTouchesEnd(i,ys);
21. }

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

1. voidccTouchEnded(cocos2d::CCTouch*pTouch,cocos2d::CCEvent*pEvent)
2. {
3. do
4. {
5. if(mTelNumber){
6. CCPointendPos=pTouch->getLocation();
8. floatdelta=5.f;
9. if(::abs(mBeginPos.x-endPos.x)>delta
10. ||::abs(mBeginPos.y-endPos.y)>delta){
11. break;
12. }
14. //看编辑框是否被点中
15. CCPointpoint=mTelNumber->getParent()->convertTouchToNodeSpaceAR(pTouch);
17. //锚点(0.f,0.5f)
18. //intx=mTextField->getParent()->getPosition().x;
19. //inty=mTextField->getParent()->getPosition().y;
20. intw=mTelNumber->getContentSize().width;
21. inth=mTelNumber->getContentSize().height;
22. CCRectrect=CCRect(0,-h/2,w,h);
24. onClickedTextField(rect.containsPoint(point));
25. }
26. }while(0);
28. DialogLayer::ccTouchEnded(pTouch,pEvent);
29. }
31. /**点击推广码输入框*/
32. voidonClickedTextField(boolb)
33. {
34. if(b){
35. mTelNumber->attachWithIME();
36. }else{
37. mTelNumber->detachWithIME();
38. }
39. }
