在为设备编译时，Apple Mach-O连接器错误

我刚刚升级到xcode 4.0，我不能再部署到iPhone，我得到一个苹果Mach-O链接器错误，它仍然适用于模拟器。

我可以通过编辑“库搜索路径”来修复这个错误。

它首先出现是因为我移动了几个文件夹，最终给了我的构建设置两个不同的搜索路径，因为当你链接一个库/框架时，它们会自动添加到你的构建设置中，但它们并不总是被删除。

因此，如果你将一个链接的库/框架移动到不同的目录并重新链接它，你将不得不手动编辑搜索路径。

你可以通过在移动之前删除库/框架来避免这种情况，但我还没有对此进行测试。

我的具体错误是:

Ld:入口点(_main)未定义。架构armv7

这应该是显而易见的，但这是因为主要。m没有包含在构建阶段下的编译源代码中

如果你用相同的名字定义了NSObject:

NSObject *notUniqueObj;

即使在2个不同的文件中(如果您在另一个文件中导入一个文件)，它也会给您一个错误。给它们起不同的名字。

当我得到这个错误时，我想分享另一个原因:

我在project Navigator(在Xcode 6.1.1中)中更改了项目名称，只需单击它，我的项目就无法编译。我把项目名称改回原来的名字，项目正在建设。非常非常奇怪，但我确实遇到过这种情况。我希望这些信息能有所帮助。

在我的情况下，我有包括.m文件，这就是为什么编译器显示这种类型的错误。

你应该检查最近导入的文件不是。m文件“某个时候i”

My problem was that in multiple class.m files I had created an NSString named TAG, and I had set the value of TAG to the String name of each class (Ex: NSString * TAG = HWGuiControl). I had done so that then it was easy to prepend my NSLog statements with the name of the class. (I have used this system in Android with great success, great for analyzing program flow 2 years later). Deploying to a device, this all works great. But when its time to create an Archive for distribution, apparently the linker cannot contend with the NSString named TAG appearing in multiple files. Modifying the name(s) of TAG to HWGTAG, etc, did the trick.
