首先，我的Cocos2dx 版本比较旧

cocos2d.x.version: 2.1rc0-x-2.1.4

一直没有时间升级…… 最近对旧项目在XCode7下重新编译，发现了很多很多问题……

一个重要的问题是：输入框CCEditBox接收焦点后，画面马上偏移！无法正常使用。

搜索了许多资料，总结解决方法如下：

1、官方的方法是在：

https://github.com/cocos2d/cocos2d-x/pull/8149

2、按照1修改后，能够进入输入了，画面不移动了，但是输入完成后，画面还是跑了！

再进行下述修改，则问题解决，并验证了iOS7等系统下正常运行！

CCEAGLView-ios.mm
-(void) doAnimationWhenKeyboardMoveWithDuration:(float)duration distance:(float)dis

    switch (getFixedOrientation([[UIApplication sharedApplication] statusBarOrientation]))
    {
        case UIInterfaceOrientationPortrait:
            self.frame = CGRectMake(originalRect_.origin.x, originalRect_.origin.y - dis, originalRect_.size.width, originalRect_.size.height);
            break;

        case UIInterfaceOrientationPortraitUpsideDown:
            self.frame = CGRectMake(originalRect_.origin.x, originalRect_.origin.y + dis, originalRect_.size.width, originalRect_.size.height);
            break;

        case UIInterfaceOrientationLandscapeLeft:
            self.frame = CGRectMake(originalRect_.origin.x - dis, originalRect_.origin.y , originalRect_.size.width, originalRect_.size.height);
            break;

        case UIInterfaceOrientationLandscapeRight:
            self.frame = CGRectMake(originalRect_.origin.x + dis, originalRect_.origin.y , originalRect_.size.width, originalRect_.size.height);
            break;

        default:
            break;
    }

修改成

    switch (getFixedOrientation([[UIApplication sharedApplication] statusBarOrientation]))
    {
        case UIInterfaceOrientationPortrait:
            self.frame = CGRectMake(originalRect_.origin.x, originalRect_.origin.y - dis, self.frame.size.width, self.frame.size.height);
            break;

        case UIInterfaceOrientationPortraitUpsideDown:
            self.frame = CGRectMake(originalRect_.origin.x, originalRect_.origin.y + dis, self.frame.size.width, self.frame.size.height);
            break;

        case UIInterfaceOrientationLandscapeLeft:
            self.frame = CGRectMake(originalRect_.origin.x - dis, originalRect_.origin.y , self.frame.size.width, self.frame.size.height);
            break;

        case UIInterfaceOrientationLandscapeRight:
            self.frame = CGRectMake(originalRect_.origin.x + dis, originalRect_.origin.y , self.frame.size.width, self.frame.size.height);
            break;

        default:
            break;
    }
