keyboard splitting bug on ipad with ios 5 and 6 (Cocos2d-x)

Had the same issue - the solution is to stop the opengl layer from rendering while this is happening. Here’s what I did:

1) Register for keyboard frame change events at start of application. I did this in AppController.mm

- (BOOL)application:(UIApplication
*)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

...



[[NSNotificationCenterdefaultCenter]
addObserver:self

selector:@selector(keyboardWillChangeFrame:)

name:UIKeyboardWillChangeFrameNotification

object:nil];//UIKeyboardWillChangeFrameNotification

[[NSNotificationCenterdefaultCenter]
addObserver:self

selector:@selector(keyboardDidChangeFrame:)

name:UIKeyboardDidChangeFrameNotification

object:nil];



...

}

2) Started and stopped rendering during keyboard animation.

-(void)keyboardWillChangeFrame:(NSNotification *)notification {

NSLog(@"keyboardWillChangeFrame");

// stop openGL animation while animating keyboard

cocos2d::CCDirector::sharedDirector()->stopAnimation();

}

-(void)keyboardDidChangeFrame:(NSNotification *)notification {// restart openGL animation
when keyboard stops animating

cocos2d::CCDirector::sharedDirector()->startAnimation();

}

上面是从google上搜出来的答案，百度找了非常久没找到答案。 ：《  google常常不好用。。。

okay，到眼下为止。键盘分拆，浮动，收回动作能够完美展现。可是出现了一点瑕疵，键盘收起时，会出现输入框中的字有闪烁，以挑剔的眼光来说，这是个问题：

看上面代码，在键盘出现变化时。停止全部的动画。键盘结束时继续，debug后发现就是在动画停止的时候文字消失。開始动画后出现。

推断是由于控件儿在停止编辑事件／键盘收起事件中有又一次设置文字信息。

经过查找：在CCEditBoxImplIOS.mm中发现了－－－

- (BOOL)textFieldShouldEndEditing:(UITextField *)sender

{

CCLOG("textFieldShouldEndEditing...");

editState_ =
NO;

getEditBoxImplIOS()->setText(getEditBoxImplIOS()->getText());

cocos2d::extension::CCEditBoxDelegate* pDelegate =
getEditBoxImplIOS()->getDelegate();

if (pDelegate != NULL)

{

pDelegate->editBoxEditingDidEnd(getEditBoxImplIOS()->getCCEditBox());

pDelegate->editBoxReturn(getEditBoxImplIOS()->getCCEditBox());

}

cocos2d::extension::CCEditBox*  pEditBox=
getEditBoxImplIOS()->getCCEditBox();

if (NULL != pEditBox && 0 != pEditBox->getScriptEditBoxHandler())

{

cocos2d::CCScriptEngineProtocol* pEngine =
cocos2d::CCScriptEngineManager::sharedManager()->getScriptEngine();

pEngine->executeEvent(pEditBox->getScriptEditBoxHandler(),
"ended",pEditBox);

pEngine->executeEvent(pEditBox->getScriptEditBoxHandler(),
"return",pEditBox);

}

if(editBox_ !=
nil)

{

// getEditBoxImplIOS()->onEndEditing(); //就是这里，onEndEditing又一次给设置内容了，似乎内容没有不论什么的变化

}

return
YES;

}

void
CCEditBoxImplIOS::onEndEditing()

{

m_systemControl.textField.hidden =
YES;

if(strlen(getText()) == 0)

{

m_pLabel->setVisible(false);

m_pLabelPlaceHolder->setVisible(true);

}

else

{

m_pLabel->setVisible(true);

m_pLabelPlaceHolder->setVisible(false);

setInactiveText(getText());

}

}

凝视掉textFieldShouldEndEditing方法。发现画面不再闪烁。 下班以后。。

。。 汗一个。这个问题从事几乎相同2天，再次感谢google，假如还找不到信息。关于疯狂

暂时还没有发现任何问题。我们欢迎评论！
