Question

我的应用程序似乎在模拟器中运行良好，但是我第一次将手机连接到我的系统并为它构建它我有一个巨大的错误日志，其中包括：

使用配置Debug

它一直在继续。

在底部/靠近底部，它说：

collect2: ld returned 1 exit status

我做错了什么？

Answer 1

解决方案帮助了我：

右键点击目标 - ＆gt;获取信息 - ＆gt; “构建”标签 - ＆gt;使用名称设置：框架搜索路径添加值“$（SDKROOT）$（SYSTEM_LIBRARY_DIR）/ Frameworks”并将其移至路径列表顶部

Answer 2

您是否指定了这些路径？看着它们，它们都指向：/Developer/Platforms/iPhoneSimulator.platform / ...这解释了为什么你收到file is not of required architecture错误;它期待设备库及其发现模拟器库。

Answer 3

旧的iPhone项目可能将“框架搜索路径”设置为不存在的SDK，如：

*/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.2.1.sdk/System/Library/Frameworks*

由于这是硬编码，因此只要XCode更新删除了SDK就会中断。然后模拟器构建失败，找不到基本符号，如“_OBJC_CLASS _ $ _ NSString”

Target的“框架搜索路径”的灵活设置确实是： $（SDKROOT）$（SYSTEM_LIBRARY_DIR）/ Frameworks

“ iOS部署目标”需要至少更新为 iOS 3.0 。

设置好后，我可以在模拟器中运行我的旧应用程序。

当我尝试在iphone上构建我的应用程序时，为什么会出现“文件不是必需的架构”？
