重用工具栏/按钮图标很好，Apple 可能很欣赏 UI 的一致性.许多应用程序都使用应用程序商店中未包含在核心集中的 Apple 图标.但是，使用更大"的艺术作品会受到反对，例如飞溅艺术/库存图片.

Reusing toolbar / button icons is fine and Apple probably appreciates UI consistency. Many many apps make use of the Apple icons not included in the core set which are in the app store. Using 'larger' art will be frowned upon though, like splash arts / stock images.
