使用iOS获取特定JSON数据/进行查询

Question

我已经在我的网站上安装了wordpress的 JSON api 。我可以使用wordpress和内容页面中的某些特定内容从网站上检索图片，并在带有JSON的 iOS应用中使用它。

以下是我收到的JSON数据：

<p><strong style=\"font-size: 13px;\">3rd March</strong></p>\n<p>Swell is 5 foot and cross shore, bitter in the cold wind.

所以在这个JSON数据中，我提供了我需要的一切，但是如何选择好的信息呢？我们可以查询吗？ 我想获取这些数据（来自截图）

我该怎么做？ 我还有一个名为＆＃34; excerpt＆＃34;在JSON数据中包含这些数据（只是我需要的文字，没有图片）：<p>3rd March Swell is 5 foot and cross shore, bitter in the cold wind. Maybe streedagh. High tide: 1703 3.6m CLICK HERE FOR LIVE PEAK WEBCAM Low Tide: 1041 0.8m 3 day forecast to March 5th Good swell all weekend but the winds are changing. Keep in an eye for gaps in the wind. […]</p>\n但是我可以删除像<p>这样的HTML标记，并跳过日期之后的一行（例如我想到了＃34} ; 1月，2月，3月......＆＃34; [阵列]，跳过一条线？

在High Tide之前，跳过一条线。 在Low Tide之前，跳过一条线。 ...
