您要安装的应用程序是针对Arm体系结构编译的应用程序，与模拟器不同(模拟器不是模拟器).该模拟器仅运行为其编译的x86应用程序.您将需要与应用程序的开发人员联系，以向您发送x86二进制文件，并将它们直接添加到iOS模拟器的应用程序目录中.该目录(在Xcode 4.5 beta 4上)是/Applications/Xcode45-DP4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/Applications.请注意，模拟器的sdk版本必须与您要使用该模拟器的iOS版本匹配.

The app you are trying to install is an app compiled for arm architecture, which is different from the simulator (the simulator is not an emulator). The simulator only runs x86 apps compiled for it. You will need to contact the developer of the application to send you the x86 binaries, and add them directly to the application directory of the iOS simulator. The directory (on Xcode 4.5 beta 4) is /Applications/Xcode45-DP4.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator5.1.sdk/Applications. Note that the simulator's sdk version has to match the version of iOS you are trying to use the simulator with.
