斯威夫特：通过引用传递数组？ [英] Swift: Pass array by reference?

问题描述

我想通过我的雨燕阵列 account.chats 到 chatsViewController.chats 引用（所以，当我加入聊天 account.chats ， chatsViewController.chats 仍然指向 account.chats ）。即，我不希望斯威夫特两个数组分开时长 account.chats 的变化。

I want to pass my Swift Array account.chats to chatsViewController.chats by reference (so that when I add a chat to account.chats, chatsViewController.chats still points to account.chats). I.e., I don't want Swift to separate the two arrays when the length of account.chats changes.

推荐答案

我最终只是让帐户全局变量和定义的聊天 ChatsViewController 的属性为： VAR聊天：聊天] {返回account.chats} 。有关详细信息，请参阅 Acani聊天。

I ended up just making account a global variable and defining the chats property of ChatsViewController as: var chats: [Chat] { return account.chats }. For details, see Acani Chats.
