NSDictionaryOfVariableBindings swift等价？ [英] NSDictionaryOfVariableBindings swift equivalent?

问题描述

Apple文档显示UIKit参考的创建字典部分下的空白空间这里。

The Apple documentation shows an unsettling blank space under the 'Creating a Dictionary' section of the UIKit reference here.

有没有人找到 NSDictionaryOfVariableBindings 宏的替代品，或者我们是否只想写自己的？

Has anyone found a replacement for the NSDictionaryOfVariableBindings macro, or are we expected to just write our own?

编辑 - 根据这个或许正确的方法是编写一个全局函数来处理这个问题？看起来复杂的宏完全不存在。

EDIT - According to this perhaps the right approach is to write a global function to handle this? Looks like complex macros are out entirely.

推荐答案

根据Apple源代码：

According to Apple source code:

NSDictionaryOfVariableBindings（v1，v2，v3）相当于[NSDictionary dictionaryWithObjectsAndKeys：v1，@v1，v2，@v2，v3，@v3，nil];

NSDictionaryOfVariableBindings(v1, v2, v3) is equivalent to [NSDictionary dictionaryWithObjectsAndKeys:v1, @"v1", v2, @"v2", v3, @"v3", nil];

所以在Swift中你也可以这样做：

So in Swift you can do the same using:

let bindings = ["v1": v1, "v2": v2, "v3": v3]
