Question

API需要在url查询参数中传递数组，如何在iOS中实现这一点？

我只知道如何传递单个vaue，例如下面的API：?title=Design Milk&id=feed/http://feeds.feedburner.com/design-milk

API示例：

  "title": "Design Milk",
  "id": "feed/http://feeds.feedburner.com/design-milk",
  "categories": [
    {
      "id": "user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/design",
      "label": "design"
    },
    {
      "id": "user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/weekly",
      "label": "weekly"
    },
    {
      "id": "user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/global.must",
      "label": "must reads"
    }
  ]

创建一个集合，然后使用NSJSONSerialization创建JSON数据表示。将结果数据用作POST数据。

NSDictionary *parameters = @{
  @"title": @"Design Milk",
  @"id": @"feed/http://feeds.feedburner.com/design-milk",
  @"categories": @[
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/design",
              @"label": @"design"
              },
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/weekly",
              @"label": @"weekly"
              },
          @{
              @"id": @"user/c805fcbf-3acf-4302-a97e-d82f9d7c897f/category/global.must",
              @"label": @"must reads"
              }
          ]
};

NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictData options:0 error:&error];

如何在objective-c中使用nsurl在url查询参数中传递数组？
