Xcode, iPhone: How to detect simulator target at compile time?
提问by Thomas Tempelmann
I wonder if, when building an iPhone app for the Simulator, there are special DEFINEs added that allow me to conditionally compile for this case?
我想知道在为模拟器构建 iPhone 应用程序时，是否添加了特殊的 DEFINE 允许我有条件地针对这种情况进行编译？
If not, I'll have to add my own targets for this case, but I'd rather have an automatic way of detection.
如果没有，我将不得不为这种情况添加我自己的目标，但我宁愿有一种自动检测方式。
Alternatively, is there a dynamic way to know when my code runs on the Simulator, I mean something that's documented? I've been searching the docs for a while now but had no luck yet.
或者，是否有一种动态方式可以知道我的代码何时在模拟器上运行，我的意思是有记录的内容？我一直在搜索文档一段时间，但还没有运气。

For compile-time check you need TARGET_IPHONE_SIMULATOR defined in TargetConditionals.h
对于编译时检查，您需要在 TargetConditionals.h 中定义 TARGET_IPHONE_SIMULATOR
#if TARGET_IPHONE_SIMULATOR
// Simulator code
#endif
For run-time check you can use for example -modelmethod in UIDevice. For iPhone simulator it returns iPhone Simulatorstring (not sure about iPad simulator though)
对于运行时检查，您可以使用-modelUIDevice 中的示例方法。对于 iPhone 模拟器，它返回iPhone Simulator字符串（虽然不确定 iPad 模拟器）

@Update :
In iOS 9.0 SDK, TARGET_IPHONE_SIMULATOR is - DEPRECATED.
use TARGET_OS_SIMULATOR instead of TARGET_IPHONE_SIMULATOR
@更新：
在 iOS 9.0 SDK 中，TARGET_IPHONE_SIMULATOR 已弃用。使用 TARGET_OS_SIMULATOR 而不是 TARGET_IPHONE_SIMULATOR
#if TARGET_OS_SIMULATOR
// Simulator code
#endif
from Swift 4.1:
从 Swift 4.1 开始：
#if targetEnvironment(simulator)
// code for the simulator here
#else
// code for real devices here
#endif
