How to determine if an app is running in the iphone simulator?

If you want to determine if your app is running on the iPhone Simulator or on a device just put the following code somewhere in your app:

#if TARGET_IPHONE_SIMULATOR
    NSLog(@"Hey there! We're running on 'iPhone Simulator'");
#elif TARGET_OS_IPHONE
    NSLog(@"Attention please! We're running on an 'iOS Device");
#endif

This is also an easy way to put in some definitions. For example if the player should run faster on the simulator:

#if TARGET_IPHONE_SIMULATOR
#define MAX_PLAYER_SPEED 145.0
#elif TARGET_OS_IPHONE
#define MAX_PLAYER_SPEED 333.0
#endif

How to count the lines of an Xcode project

The easiest way is to open the terminal app and navigate to the Xcode project and paste the following line:

find . "(" -name "*.m" -or -name "*.h" -or -name "*.mm" -or -name "*.cpp" ")" -print0 | xargs -0 wc -l

 You will get an result similar like this one:

terminal output

So now you know the lines per file and at the end the lines total of all the *.h and *.m files.
