** 由于此文年事已久，可能某些 URL Schemes 已失效，可在评论区留言指出！(最后更新于 2024.10.28)
由于苹果的各应用都是在沙盒中，不能够互相之间访问或共享数据。但是苹果还是给出了一个可以在 APP 之间跳转的方法：URL Scheme。简单的说，URL Scheme 就是一个可以让 APP 相互之间可以跳转的协议。每个 APP 的 URL Scheme 都是不一样的，如果存在一样的 URL Scheme，那么系统就会响应先安装那个 APP 的 URL Scheme，因为后安装的 APP 的 URL Scheme 被覆盖掉了，是不能被调用的。
Apple will reject apps that are using private url schemes (Ugh, Apple....) if they are pretty much obvius. Some apps are rejected and others are not, so, be aware of this issue before implementing any of those URL's in your app as a feature.
