运行在iPhone 5S的64位32位的库 [英] Run 32 bit library on iPhone 5s 64 bit

问题描述

我'使用 zbar 在我的应用程序。如果我想用一个64位处理器在我的iPhone 5S运行它，我得到了以下错误：

I'am using zbar in my application. If I want to run it on my iPhone 5s with an 64 bit processor, I get the following errors:

是否有可能使用32位库64位的设备上，因为我不认为，该库将被更新。

Is it possible to use the 32 bit library on a 64 bit device, because I don't think, the library is going to be updated.

推荐答案

要总结上述评论。一个64位的iPhone应用程序需要的所有成分库和框架是64位。你不能混搭。离开一个应用程序的32位非最优的长期，因为iOS的必须保持两个版本装（32和64）的系统库，一旦一个32位的应用程序运行。因此，你不想成为最后的应用程序，支持64位！

To summarize the comments above. A 64bit iPhone application requires all constituent libraries and frameworks to be 64bit. You can't mix and match. Leaving an application 32bit is non-optimal long term since iOS has to keep two versions of the system libraries loaded (32 and 64) as soon as a single 32bit app is run. Hence, you don't want to be the last app to support 64bit!

您可以检查您的库包含64位code。使用脂。例如，这里的SBJson框架32位：

You can check if your library contains 64bit code using lipo. For example, here's the SBJson framework in 32bit:

$ lipo -info SBJson.framework/SBJson 
Architectures in the fat file: SBJson.framework/SBJson are: armv6 armv7 i386 

和使用64位code

and with 64bit code

$ lipo -info SBJson.framework/SBJson
Architectures in the fat file: SBJson.framework/SBJson are: armv7 armv7s i386 x86_64 arm64 

在zbar的情况下，如果它不是用你总是可以尝试从源代码编译自己。

In the case of zbar, if it's not available you could always try compiling yourself from source.
