Cocos2dx iOS批准的应用程序崩溃

kub*_*kub 5 iphone cocos2d-iphone ios cocos2d-x

所以我在这个非常奇怪和恼人的问题上被困了几天.所以我有一个应用程序,我发布到ios应用商店,我最近回去并为应用程序添加了一些额外的功能.我没有触摸应用程序的核心,只是添加了诸如twitter,facebook,app应用程序和google admob(基于完整版的免费版本).所以这里的事情变得奇怪.我测试了我的更新我做了一个adhoc发布版本并在我的iphone 3gs,4s,ipad 2上测试 - 没有任何问题.我提交给苹果他们批准了更新,它已经发布.我更新了应用程序并尝试运行它并在启动画面后立即崩溃(此处没有任何更改).我的项目使用cocos2dx框架(版本cocos2d-2.0-x-2.0.4 @ 2012年11月2日),我使用cocosbuilder(2.1).我查看了日志,它似乎是CCBReader :: readFloat()函数内部的一个未对齐问题.我发现这里有一个解决方法:https://github.com/DarraghCoy/cocos2d-x/commit/34b31fd754778f815fcac108089e3fe015e2e2b9.

所以我继续修改我的默认情况:float CCBReader :: readFloat(){unsigned char type = this-> readByte();

        switch (type) {
            case kCCBFloat0:
                return 0;    
            case kCCBFloat1:
                return 1;
            case kCCBFloatMinus1:
                return -1;
            case kCCBFloat05:
                return 0.5f;
            case kCCBFloatInteger:
                return (float)this->readInt(true);
            default:
                {
                    /* using a memcpy since the compiler isn't
                     * doing the float ptr math correctly on device.
                     * TODO still applies in C++ ? */
                    float * pF = (float*)(this->mBytes + this->mCurrentByte);
                    float f = 0;

                    memcpy( &f, pF, sizeof(float));
                    this->mCurrentByte += 4;

                    return f;
                }
        }
    }

对此:

    float CCBReader::readFloat() {
        unsigned char type = this->readByte();

        switch (type) {
            case kCCBFloat0:
                return 0;    
            case kCCBFloat1:
                return 1;
            case kCCBFloatMinus1:
                return -1;
            case kCCBFloat05:
                return 0.5f;
            case kCCBFloatInteger:
                return (float)this->readInt(true);
            default:
                {
                    /* using a memcpy since the compiler isn't
                     * doing the float ptr math correctly on device.
                     * TODO still applies in C++ ? */
                    float * pF = (float*)(this->mBytes + this->mCurrentByte);
                    float f = 0;

                    memcpy((void*) &f, (const void*) pF, sizeof(float));

                    this->mCurrentByte += sizeof(float);


                    return f;
                }
        }
    }

再次在设备上测试版本构建没有问题.我向苹果提交了此修复程序,并请求加急审核,以便应用程序运行而不是崩溃,并在1天内获得苹果批准并被运出.我更新到新版本的发布,并再次崩溃.

我修改了其他链接器标志以包含-lsqlite3.0和-ObjC(最初它只是-lxml2和-lz).我的发布版本优化是-Os(最快,最小).

其他人有这个问题吗？我不知道如何调试这个,因为我无法重复.最后苹果如何批准该应用程序,但它在启动画面后崩溃了？如果我可以猜测它运行时它的工作原理可能会在应用程序批准(不确定)之后扔掉"处理App Store"阶段时被破坏.

谢谢!

我当时就想“CCB 在那里做什么？” ....无论如何，尝试使用 -O3 或根本不进行优化。已知 -Os 会导致微妙的问题，尤其是对于 cocos2d。-Os 不是 cocos2d 的默认级别是有原因的（我也相信 Xcode 模板也是如此）。

如果这解决了问题，您可以使用此问题的答案之一设置优化级别或仅针对此文件或函数禁用优化。
