排序的NSDictionary的NSArray的斯威夫特对象 [英] Sort NSArray of NSDictionary objects in Swift

问题描述

我已经取回来自API的一些JSON数据，现在有一个NSArray充分的NSDictionary对象。每一个的NSDictionary有一个键/值对名的，我想通过键/值对的NSArray的排序。

I have retrieved some JSON data from an API and now have an NSArray full of NSDictionary objects. Each NSDictionary has a key/value pair of "name" and I want to sort the NSArray by that key/value pair.

我已经做了搜索，但没有我遇到的解决方案似乎在新雨燕语言的工作相当多，我不知道这是否是可能的错误或不...

I've done quite a bit of searching but none of the solutions I've come across seem to work in the new Swift language and I'm not sure if it's possibly a bug or not...

我试过：

var descriptor: NSSortDescriptor = NSSortDescriptor(key: "name", ascending: true)
var sortedResults: NSArray = results.sortedArrayUsingDescriptors(NSSortDescriptor(key: "name", ascending: true))

但是，这不会编译指出NSSortDescriptor是无法转换为[AnyObject]。

But that won't compile stating "NSSortDescriptor is not convertible to [AnyObject]".

任何意见？

推荐答案

您必须通过某种描述符的数组（即使它只有一个）：

you must pass an array of sort descriptors (even if it's only one):

var descriptor: NSSortDescriptor = NSSortDescriptor(key: "name", ascending: true)
var sortedResults: NSArray = results.sortedArrayUsingDescriptors([descriptor])
