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。
注意：结合使用 Application.genuineCheckAvailable 和 Application.genuine 来验证应用程序完整性。访问 Application.genuine 属性是一项资源密集型操作，因此请勿在更新帧或运行其他时间关键代码期间调用该属性。
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. See iOS Scripting and Android mobile scripting for more information.
