I have problem with this json data:
{"return":"{\"productsList\":
[{\"BrandUID\":0,\"BrandName\":\"KAIREE\",\"ProductUID\":213,\"ProductName\":\"ANARKALI NET
WITH BANARASI
INNER\",\"Address\":\"\",\"Email\":\"\",\"Phone\":\"\",\"Price\":\"15000.00\",\"MainImage\":
\"http:\\\/\\\/tagin.xspl.in:8888\\\/images\\\/medium\\\/IMG_2635.JPG\",\"TagCount\":0},
{\"BrandUID\":0,\"BrandName\":\"KAIREE\",\"ProductUID\":245,\"ProductName\":\"SILK CHOODIDAR
SUIT\",\"Address\":\"\",\"Email\":\"\",\"Phone\":\"\",\"Price\":\"5195.00\",\"MainImage\":\
"http:\\\/\\\/tagin.xspl.in:8888\\\/images\\\/medium\\\/IMG_2696.JPG\",\"TagCount\":0},
{\"BrandUID\":0,\"BrandName\":\"ROOP SANGAM\",\"ProductUID\":124,\"ProductName\":\"KOTA
SILK\",\"Address\":\"\",\"Email\":\"\",\"Phone\":\"\",\"Price\":\"1050.00\",\"MainImage\":\"
http:\\\/\\\/tagin.xspl.in:8888\\\/images\\\/medium\\\/DSC_0181.JPG\",\"TagCount\":0}]}"}
can please some help me...I want array of image urls i.e of keys MainImage.
How can I do it using NSJSONSerialization

Answer 1

This looks like "nested JSON": the value of the "return" key is a string that itself
contains a complete JSON object. In that case you have to de-serialize twice,
something like this:
NSData *jsonData = ... // your JSON data
NSError *error;
NSDictionary *outerObject = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error: &error];
NSData *innerJson = [outerObject[#"return"] dataUsingEncoding:NSUTF8StringEncoding];
NSDictionary *innerObject = [NSJSONSerialization JSONObjectWithData:innerJson options:0 error:&error];
And now you can access the inner JSON object, for example:
NSArray *productsList = innerObject[#"productsList"];
NSArray *mainImages = [productsList valueForKey:#"MainImage"];

Answer 2

Try this
id mainDict = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingAllowFragments error:&parseError];
Note:- here data is your response coming from server.
Now when you saw carefully above JSON data, the things wrapped inside {(curly bracket) are in the form of dictionary. And the things that are wrapped inside [(square bracket)are in the form of array.
So you can parse your data by following code,as our data is in maindict
NSArray *array = [[maindict valueForKey:#"return"]valueForKey:#"productsList"]];
Now when you print array you will get 3 elements in array.

Answer 3

Are you sure your JSON data is valid?
For example, this is valid JSON
{"\"key\"": "value"}
This is not:
{\"key\": "value"}

Answer 4

Please check the JSON data, i have modified, with extra "}"
{
"productsList": [
