尝试编译 MobileSubstrate 插件 - 未定义的符号
我通过本教程创建了一个 MobileSubstrate 插件。我可以毫无错误地编译示例挂钩。
但是，一旦我添加
#import <SpringBoard/SBAwayController.h>
ExampleHookProtocol.h 和
SBAwayController *awayController = [SBAwayController sharedAwayController];
ExampleHookLibrary.mm （作为 __$ExampleHook_AppIcon_Launch 函数的第一行），我就得到了尝试 make 时出现以下错误消息（由后一个更改触发）：
Undefined symbols:
"_OBJC_CLASS_$_SBAwayController", referenced from:
__objc_classrefs__DATA@0 in ExampleHookLibrary.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [ExampleHook.dylib] Error 1.
SBAwayController 的头文件位于 /var/toolchain/sys30/usr/include/SpringBoard ，就像ExampleHook 使用的SBApplicationIcon.h 一样。
我正在我的 iPod touch 2G 上进行编译。
谁能帮助我吗？
预先感谢，
埃里克
I went through this tutorial to create a MobileSubstrate addon. I could compile the example hook without errors.
But as soon as I add
#import <SpringBoard/SBAwayController.h>
in ExampleHookProtocol.h and
SBAwayController *awayController = [SBAwayController sharedAwayController];
in ExampleHookLibrary.mm (as the first line of the __$ExampleHook_AppIcon_Launch function) I get the following error message when attempting to make (triggered by the latter change):
Undefined symbols:
"_OBJC_CLASS_$_SBAwayController", referenced from:
__objc_classrefs__DATA@0 in ExampleHookLibrary.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
make: *** [ExampleHook.dylib] Error 1.
The header file for SBAwayController is located in /var/toolchain/sys30/usr/include/SpringBoard, just like SBApplicationIcon.h, which is used by the ExampleHook.
I'm compiling on my iPod touch 2G.
Can anyone help me?
Thanks in advance,
Eric

由于编译时没有任何可链接的内容，因此需要在运行时获取该类，因此添加
初始化程序，并更改
为
Since there is nothing to link to when you compile, you need to get the class at runtime, so add
in the initializer, and change
