“Semantic error：Redefinition of'__ccContentScaleFactor'with a different type”在Cocos2D v2 [英] "Semantic error: Redefinition of '__ccContentScaleFactor' with a different type" in Cocos2D v2
问题描述
我开发了一个新游戏，它在我真正的ios设备，甚至模拟器上运行完美，但当我决定提交到AppStore它是给这个行上的错误。
i have developed a new game and it is running perfectly fine on my real ios devices and even on simulators but when i decided to submit it to AppStore it is giving error on this line.
extern CGFloat __ccContentScaleFactor;
且错误是
cocos2d/Platforms/iOS/CCDirectorIOS.h:102:16: Redefinition of '__ccContentScaleFactor' with a different type: 'CGFloat' (aka 'double') vs 'float'
任何人都可以帮我解决这个问题我只是更新xcode到5.1。感谢
can anyone please help me with this issue i just update xcode to 5.1. thanks
推荐答案
重要更新：
Cocos2D v2 .2和64位修复已被释放。
我强烈建议每个cocos2d v2.x开发人员升级到此版本，而不是应用快速修复下面。有许多64位兼容性问题潜伏在cocos2d v2.0和v2.1，这可能会使他们丑陋的头，在奇怪的错误，视觉上的毛刺或更多的编译错误，取决于应用程序。
Important Update:
Cocos2D v2.2 with 64-Bit fixes has been released.
I strongly suggest every cocos2d v2.x developer to upgrade to this version rather than applying the quick fix below. There are many 64-Bit compatibility issues lurking in cocos2d v2.0 and v2.1, which may rear their ugly head in weird bugs, visual glitches or more compile errors - depending on the app.
从2015年2月开始，Apple只接受包含64位二进制文件的新应用和应用升级。因此，强烈建议您在64位设备上将代码和cocos2d设置为正常工作状态。
Beginning in February 2015 Apple will only accept new apps and app upgrades which include 64-Bit binaries. So it's highly recommended to get your code and cocos2d to a proper working state on 64-bit devices.
编辑编译器所抱怨的行，更改 CGFloat 到 float ，使其显示为：
Edit the line the compiler complains about, change CGFloat to float so that it reads:
extern float __ccContentScaleFactor;
但这表明xcode正在构建arm64切片。对于cocos2d-iphone v2.x，最好禁用/从支持的体系结构中删除arm64，因为 Cocos2D v2.1及更早版本与64位设备不完全兼容！
However this indicates that xcode is building the arm64 slice. For cocos2d-iphone v2.x it is best to disable/remove arm64 from supported architectures because Cocos2D v2.1 and earlier are not fully compatible with 64bit devices!
当运行一个编译为64位代码并运行在64位设备（iPhone 5S和更高版本）上的Cocos2D v2.1或更早版本的应用程序时，可能会有奇怪的错误和副作用。这些问题可能不会在iOS模拟器上发生。
There can be weird bugs and side-effects when running a Cocos2D v2.1 or earlier app compiled as 64-bit code and running on a 64-Bit device (iPhone 5S and newer). These issues may not occur on the iOS Simulator.
