我已经被这个问题困扰了一段时间。无数个小时和时间，我仍然想不出来。我有解决这个问题的办法吗？

这是错误
ld:警告：忽略文件PumpkinMenace/Supporting Files/libyo_interpreted.a，该文件是为不是要链接的体系结构的存档而构建的（i386）：Pumpkin梅纳ce/Supporting Files/libyo_terpreted.a
体系结构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:找不到体系结构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项目都有一个"main.m"文件（在Xcode 6.1中，它通常隐藏在项目的"支持文件"文件夹中）。
如果您没有main.m文件（其中包含main C样式函数），这就是您看到错误的原因。
主要功能如下：
int main(int argc, char * argv[]) {
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
"体系结构i386的未定义符号"
可能问题出在libyointerpreted.a文件中，因为它是为ios模拟器体系结构（i386）构建的，但您试图在设备（即arm7/armv7/arm64）上运行应用程序。
为arm7/armv7体系结构重建libyo_interpreted.a。（这对我有帮助http://blog.diogot.com/blog/2013/09/18/static-libs-with-support-to-ios-5-and-arm64/)
