如果应用程序在构建后以任何方式进行了更改，则返回 false。
否则返回 true。
Note: Use Application.genuineCheckAvailable along with Application.genuine to verify app integrity. Accessing the Application.genuine property is a resource-intensive operation, so do not call it during frame updates or other time-critical code.
Android: Returns false if the package name set in project settings mismatches with package name returned at runtime.
You can use this as an anti-piracy check because it checks if the application was altered after being built. Refer to iOS Scripting and Android mobile scripting for more information.
