提取字典的值

Question

struct Country {
  var translations : [String:String?]? // must be defined as optionals!
}

// example entry
translationsDict = [
   "translations": [
      "de":"Deutschland", 
      "en": "germany",
      "it": nil
   ]
]

如何将“Deutschland”和“germany”值提取到新阵列中？ 结果应该是：

 ["germany", "Deutschland"]

Answer 1

首先，获取翻译的所有值的集合，然后将其转换为数组。

@extends('layouts.app')
@section('content')
  <div class="container">
      <div class="row">
        <div class="col-md-12">
          <ul class="breadcrumb">
            <li><a href="{{ url('/home') }}">Dashboard</a></li>
            <li class="active">Jadwal</li>
          </ul>
          <div class="panel panel-default">
            <div class="panel-heading">
              <h2 class="panel-title">Lapangan</h2>
            </div>
            <div class="panel-body">
              {!! $html->table(['class'=>'table-striped table-bordered']) !!}
            </div>
          </div>
        </div>
      </div>
    </div>
@endsection
@section('scripts')
  {!! $html->scripts() !!}
@endsection

或

if let collection = translationsDict["translations"]?.values {
    let array = Array(collection)
    print(array)
}
