Question

可能重复：
Is it possible to target older iOS versions when using Xcode 4.2 and iOS 5 SDK?

我有一个问题，我真的不明白，我使用Xcode直到昨天所有工作完美，但昨天我用iOS 5安装Xcode 4.2，但现在当我尝试用我的iPhone设置运行目标是成功构建应用程序，然后立即停止。没有错误，控制台日志中没有任何内容。该应用程序甚至没有复制到我的设备。 Xcode说：建设，运行，完成运行....所有都在2秒内...... 在模拟器上一切正常，但在设备上没有任何事情发生。

我有iOS 5的xCode 4.2，我有iphone 4.2.1的iPhone 3G，在部署目标下，我选择4.2就像去年一样。请帮帮我，我疯了！

我在Xcode的组织者窗口看到，日志给了我这个结果，我复制了一小部分：

有什么问题？

P.S。我试图将架构设置为armv6并在设备上构建问题是什么？...但它是如何改变的？...我从来没有改变Xcode上的架构。

Answer 1

你是对的 - 问题可能是3G运行amrv6并且你只是为armv7构建

在您的构建设置中，您可以找到有效架构的设置。应该有一个名为armv7的条目

只需将另一个条目armv6添加到该设置即可。应该做的伎俩

Answer 2

如果您正在使用xcode 4.2并希望将应用程序安装到设备上，请按照HeikoG告诉的步骤进行操作，但在执行此操作后它也无法帮助我。但最后我发现在info.plist中，他们在关键部分定义了“必需的设备功能”，所以只需删除它并安装应用程序。

Answer 3

还有另一个地方你需要添加armv6。它位于Build Settings下的Architectures类下的Architectures下。

Xcode Build Succeeded但不能在iPhone上运行
