请告诉我如何从JSON上面获取名称和recipe_image。到目前为止我搜索的是这些链接：
help me to parse JSON value using JSONTouch
http://www.iphonedevsdk.com/forum/iphone-sdk-development/81895-nested-json-nsdictionary-integer.html
How do I parse this nested JSON output in Objective C?
How to parse nested JSON objects with JSON framework and Objective-C/iPhone/Xcode?
How can I pull out nested JSON values in a collection in objective-C?
答案 0 :(得分：0)
我建议使用在github https://github.com/stig/json-framework上找到的SBJson阅读器，然后找到自己的XML解析器，Ray Wenderlich对于iOS的不同XML解析器有很好的基准标记
