xcode - 体系结构i386的 undefined symbol : “__products” , referenced from:

Question

在尝试运行项目时，我会遇到以下错误，我可以使用一些帮助。

我的项目已经通过应用内购买发布。
在最新版本中，我尝试将IAP合并到另一个 View Controller 中，但是当我要运行时，也会遇到两个Apple Mach-O Linker Error和一个Dsymutil Error。

自上次发布以来，我可能已经将Xcode(更新为4.6(4H127)版)，但是我不确定。

我已经检查过的一些东西:

用Binaries链接Binary和Binaries似乎仍然包括所有必要的框架；

编译源似乎包含我所有的.m文件；

我在代码中的任何地方都找不到__products(_products我可以找到thoug ...:我用该名称创建了一个全局变量(之前是局部变量))

我尝试在模拟器和设备上运行。

全局变量在.h文件中声明，该文件在需要它的 View Controller 中导入:
extern NSArray * _products;

我不确定我的外部框架/库是否会造成任何麻烦。他们之前工作得很好:TestFlight，Appirater，CHCSVParser。

错误:

Answer 1

并不是说“extern”很糟糕，您只需要在某个地方的.m文件顶部声明实际的“NSArray”，否则该对象实际上并没有分配到任何地方。

因此，如果在.h文件中声明“extern”变量，请在支持该.h文件的.m文件顶部声明实际变量。

例如。

NSArray * _products;

在“@implementation”位之前。并确保在.m文件中的某个位置进行该变量的分配和初始化。
