Programmatically detect if app is being run on device or simulator
提问by eugene
I'd like to know whether my app is being run on device or simulator at run time. Is there a way to detect this?
我想知道我的应用程序在运行时是在设备上还是在模拟器上运行。有没有办法检测到这一点？

#if TARGET_OS_SIMULATOR
//Simulator
#else
// Device
#endif
Pls refer this previous SO question also What #defines are set up by Xcode when compiling for iPhone
请参考这个以前的 SO 问题，当为 iPhone 编译时，Xcode 设置了什么 #defines
回答by Fernando Cervantes
I created a macro in which you can specify which actions you want to perform inside parentheses and these actions will only be performed if the device is being simulated.
我创建了一个宏，您可以在其中指定要在括号内执行的操作，并且只有在模拟设备时才会执行这些操作。
#define SIM(x) if ([[[UIDevice currentDevice].model lowercaseString] rangeOfString:@"simulator"].location != NSNotFound){x;}
This is used like this:
这是这样使用的：
SIM(NSLog(@"This will only be logged if the device is simulated"));

Check if simulator
检查模拟器
#if TARGET_IPHONE_SIMULATOR
// Simulator
#endif
Check if device
检查设备是否
#if !(TARGET_IPHONE_SIMULATOR)
// Device
#endif
Check for both
检查两者
#if TARGET_IPHONE_SIMULATOR
// Simulator
#else
// Device
#endif
Please note that you should not ifdefon
TARGET_IPHONE_SIMULATORbecause it will always be defined to either 1or 0.
请注意，您不应该ifdef打开，
TARGET_IPHONE_SIMULATOR因为它将始终定义为1或0。

TARGET_IPHONE_SIMULATORis defined on the device (but defined to false). and defined as below
TARGET_IPHONE_SIMULATOR在设备上定义（但定义为 false）。并定义如下
#if TARGET_IPHONE_SIMULATOR
NSString * const DeviceMode = @"Simulator";
#else
NSString * const DeviceMode = @"Device";
#endif
Just use DeviceModeto know between device and simulator
只是DeviceMode用来了解设备和模拟器之间
回答by Julio Gorgé
You can use the TARGET_IPHONE_SIMULATORpreprocessor macro to distinguish between device and simulator targets.
您可以使用TARGET_IPHONE_SIMULATOR预处理器宏来区分设备和模拟器目标。

From XCode 9.3+ , Swift
从 XCode 9.3+ 开始，Swift
#if targetEnvironment(simulator)
//Simulator
#else
//Real device
#endif
Helps you to code against device type specific.
帮助您针对特定设备类型进行编码。

Use this below code:
使用以下代码：
#if targetEnvironment(simulator)
// iOS Simulator
#else
// Device
#endif
Works for Swift 4and Xcode 9.4.1
适用于Swift 4和Xcode 9.4.1
