ios - AFNetworking 获取 json 值并将其保存为 NSMutablearray
<p><p>我是 ios 及其开发的新手。我有正确设置的干净代码 <code>AFNetworking</code>。我的基本 URl 的 json Encording 有 JSON 对象和数组以及值。在我的 JSON 输出中，我想在每次获取 Null 时获取“缩略图”的值。请帮助我获取我的 json 输出的“名称、缩略图、id、图像”。请找到我的 NSDictionary 类型打印对象的 NSlog。</p>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>您收到了响应，我看到的唯一问题是您无法正确检索值。</p>
<p>在从 JSON 中获取数据时，请记住获取数据的格式，即获取数组或字典。</p>
<p>看到您的回复，您将获得本身包含字典的 Array。</p>
<p>使用以下代码获取值</p>
<pre><code>NSArray *array = ;
for (NSDictionary *dict in array) {
NSInteger ids = [ integerValue];
NSString *name = ;
NSString *thumbnail = ;
NSArray *arrImages = ;
//You can use them accordingly
}
</code></pre>
<p>希望这对您有所帮助。快乐编码:) </p></p>
