提问by Sangram Mohite
I want to parse a plain JSON array like:
我想解析一个普通的 JSON 数组，如：
{
"ns": [
[
"1364987475027",
"Alert1",
"001"
],
[
"1364987475042",
"Alert2",
"001"
],
[
"1364987475058",
"Alert4",

To get the array in simple arrays of string. I found many posts with JSON dictionary arrays. But in this case the JSON is not having keys for the values. Kindly help.

Answer :NSJSONSerialization.
NSJSONSerializationclass can be used to convert JSON to Foundation objects and Foundation objects to JSON. In your case, you should use -JSONObjectWithData:options:error:of NSJSONSerializationclass to retrieve a Foundation object from given JSON data.
NSJSONSerialization类可用于将 JSON 转换为 Foundation 对象，将 Foundation 对象转换为 JSON。在你的情况，你应该使用-JSONObjectWithData:options:error:的NSJSONSerialization类从给定的JSON数据检索Foundation对象。
Sample Code :
示例代码：
NSError *error;
NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSArray *fetchedArr = [json objectForKey:@"ns"];

NSError *error = NULL;
NSData* data = [yourJsonString dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:data
options:kNilOptions
error:&error];
NSArray *resultArray = [json objectForKey:@"ns"];//resultArray contains array type objects...
I think it will be helpful to you.
我想它会对你有所帮助。

The NSJSONSerializationmethod JSONObjectWithData:options:errorcan to that. You will get a dictionary with one value for the key "ns" and the value will be an array of arrays.
该NSJSONSerialization方法JSONObjectWithData:options:error可以到。您将获得一个字典，其中包含一个键“ns”的值，该值将是一个数组数组。
