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());
}
}
。。 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！
