iphone: get User Defined variable in Target's setting by code?
As the Info.plist file is preprocessed too, you can use this approach:
Define a User defined setting in your build settings, for Example CLASS_NAME.And a key to your Info.plist-file. Name the key CLASS_NAME and set the value to ${CLASS_NAME}.
You can then access this setting by:
NSString* className = [[[NSBundle mainBundle] infoDictionary] valueForKey:@"CLASS_NAME"];
You can not directly use a variable defined in the build settings. These variables are meant to be used by build tools.
Instead define a preprocessor macro in the Preprocessor Macros Variable like 'MYVAR=5'. You can access these macros in your code like:
#if MYVAR==5 //Do something#endifPlease note, that the evaluation of these expressions happens at build-time not at runtime.
It is very typical use to just define a Macro without caring for the value. For example define 'DEBUG=1' in the debug build settings and 'RELEASE=1' in the release build settings.
You can then test using #ifdef or #ifndef
#ifdef DEBUG // Log#endif
