当我编译我的iPhone应用程序时,xCode为MyConstants.h中的变量提供了"重复符号"错误
我想如果我用过:
#import "MyConstants.h"
它会避免这种情况吗？
但我仍然有问题.
补充信息:
也许我应该问这个:
如果您需要在所有源代码文件的每个部分中访问常量...您将在.h文件中放入什么？您将使用什么来将该常量包含在代码的其他部分中.
我想(但我猜它不是)它很简单:
(不管我在哪里在任何代码中的任何地方重新定义thisIsGlobal.)
然后在我的其他每个源文件的顶部只添加"#import MyConstants.h".
我在我的iPhone应用程序中使用FastPDFKit来显示PDF.当我在模拟器上运行项目时,它工作正常.但是,当我在iPhone上运行该项目时,它给我以下错误.
duplicate symbol _value_map in:

知道为什么会这样吗？
当我在Debug and Release部分的Configuration中添加FastPDFFramework时出现错误.
在尝试构建我的项目时,我不断得到这个错误,说ld: 11 duplicate symbols for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)
我最近尝试将GPUImage实现到我的项目中,这与它有什么关系吗？我也读过类似的问题,但没有人有我的解决方案.
我正在开发一个iPhone应用程序.我对Xcode不熟悉,所以请耐心等待.我有iOS 4.1 Device SDK.当我在"Active ..."下拉框中选择"Simulator"时,我的应用程序编译没有错误并在iPhone模拟器中运行.
但是,当我在下拉框中选择"设备"时,我收到有关重复符号的以下链接器错误:

错误是奇怪的,因为它抱怨_RedirectionLimit被发现两次 …
