问题
In many of my apps I have 3 different build configurations (debug, release, sandbox). One experiences this is needed needed when working with different environments and in app purchase.
Often there are only small changes like CFBundleIdentifier. Is it possible to use GCC preprocessor macros for keeping the variation within different build configurations and at the same time only use one plist?
回答1:
For simple changes it is often not even necessary to use the C preprocessor. In these cases it is often sufficient to define a custom build setting and use the value of this setting in the Info.plist file. Build settings are expanded in Info.plist by default.
Example:
In Xcode in the project view select "Build Settings" and use the + button to add a "User-Defined Setting". Name the setting for example MY_BUNDLE_IDENTIFIER and type a value, for example MyApp.agens.no.
The open the Info.plist file, select the "Bundle identifier" key and set its value to ${MY_BUNDLE_IDENTIFIER}.
If you change the MY_BUNDLE_IDENTIFIER build setting in another configuration or target, the product will be built using the new bundle identifier.
