Please do not use this code in your apps. It was just a quick experiment and is neither tested nor secure.
- Add the files
NSBundle+OBCodeSigningInfo.mto your Xcode project.
For a given
NSBundle, call one or more of these methods to get information about its code signing state:
- (BOOL)ob_comesFromAppStore; - (BOOL)ob_isSandboxed; - (OBCodeSignState)ob_codeSignState;
