所以我在这个极其奇怪和烦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 应用程序商店，我最近回去为应用程序添加了一些额外的功能。我没有触及应用程序的核心，只是添加了 twitter、facebook、应用内购买和 google admob（基于完整版的免费版）。所以这就是事情变得奇怪的地方。我测试了我的更新我制作了一个临时版本并在我的 iphone 3gs、4s、ipad 2 上进行了测试——完全没有问题。我提交给苹果，他们批准了更新并发布了。我更新了应用程序并尝试运行它，但在启动画面后立即崩溃（这里再次没有任何更改）。我的项目使用 cocos2dx 框架（版本 cocos2d-2.0-x-2.0.4 @ Nov 02 2012），我使用 cocosbuilder（2.1）。我查看了日志，这似乎是 CCBReader::readFloat() 函数内部的未对齐问题。我发现这里有一个解决方法：https://github.com/DarraghCoy/cocos2d-x/commit/34b31fd754778f815fcac108089e3fe015e2e2b9。
所以我继续修改了我的默认情况：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;
}
}
}
再次在设备上测试发布版本没有问题。我将此修复程序提交给苹果并要求加急审查，以便应用程序运行而不是崩溃，并在 1 天内获得苹果的批准并发货。我更新到新版本发布并再次崩溃。

我确实修改了其他链接器标志以包括 -lsqlite3.0 和 -ObjC（最初它只是 -lxml2 和 -lz）。我的发布构建优化是-Os（最快，最小）。
其他人有这个问题吗？我不知道如何调试它，因为我无法重现。最后，苹果如何批准该应用程序，但它在启动画面后立即崩溃？如果我能猜到应用程序何时运行，它可能会在应用程序批准后抛出“应用程序商店处理”阶段时被破坏（不确定）。
谢谢！
