Question

用unity开发ios程序，必须要用到xcode吗

Answer 1

第一步：导出的东西肯定先会在xcode里跑一下，可能出现如下问题
u3d中调用ios方法：

一开始拿到u3d源码，导出xcode项目时出现如下报错

Undefined symbols for architecture armv7:
"_ios_onUnwearedClothes", referenced from:
RegisterMonoModules() in RegisterMonoModules.o
"_ios_onLoadUnityPlayerOK", referenced from:
RegisterMonoModules() in RegisterMonoModules.o
"_ios_onClothesWeared", referenced from:
RegisterMonoModules() in RegisterMonoModules.o
"_ios_onClothesSelected", referenced from:
RegisterMonoModules() in RegisterMonoModules.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

4.0版本的u3d导出的xcode项目是appController，但4.6版导出后是UnityAppController
上面的报错是因为在xcode中没有提供上面这些方法，要手动写到UnityAppController里

在UnityAppController.h中添加：
注意方法是否需要传入参数或返回值，我这里都是无参数无返回值的
#ifdef __cplusplus
extern "C" {
#endif
void ios_onUnwearedClothes();
void ios_onLoadUnityPlayerOK();
void ios_onClothesWeared();
void ios_onClothesSelected();
#ifdef __cplusplus
}
#endif

在UnityAppController.m中实现这些方法：
void ios_onUnwearedClothes()
{
// do something
}
void ios_onLoadUnityPlayerOK()
{
// do something
}
void ios_onClothesWeared()
{
// do something
}
void ios_onClothesSelected()
{
// do something
}
