Xcode问题“\u main”

我已经在这个问题上纠缠了一段时间了。无数个小时和时间，我仍然无法理解。我有解决这个问题的办法吗

这就是错误所在

ld：警告：忽略文件PumpkinMenace/支持文件/libyoyo_解释。a，文件是为存档而生成的，而存档不是链接的体系结构。i386:PumpkinMenace/支持文件/libyoyo_解释。a 架构i386的未定义符号： _main，引用自： 主可执行文件的隐式输入/启动 ld：未找到架构i386的符号 clang:错误：链接器命令失败，退出代码为1使用-v查看调用

是的，每个iPhone项目在Xcode 6.1中都有一个main.m文件，它通常隐藏在项目的Supporting Files文件夹中

如果您没有包含主C风格函数的main.m文件，这就是您看到错误的原因

以下是主要功能的外观：

int main(int argc, char * argv[]) {
    @autoreleasepool {
        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
    }
}

架构i386的未定义符号

可能问题出在libyoyo_.a文件中，因为该文件是为ios模拟器架构i386构建的，但您尝试在arm7/armv7/arm64设备上运行应用程序

---

为arm7/armv7架构重建libyoyo_.a。它对我很有帮助

所以我只需在支持文件中添加一个新文件，然后导入代码？也非常感谢你！
