JSon parsing error IOS with empty object key - ios

Question

Hi I have this JSON I'm trying to parse using NSDictionary and trying to get the values as mentioned . but the problem is i do not get a key when i further go into the JSON is there any way to remove this key to go more deep.
NSDictionary *Allinfo = [json objectForKey:#"Collection"];//I go into "Collection"
NSLog(#"All with response array: %#", Allinfo);
NSDictionary *datainfo = [Allinfo objectForKey:#"contact"];//i go into "contact"
after which i get
Data : (
{
attributeList = {
attribute = (
{
name = "display-name";
value = "tel:+";
},
{
name = capabilities;
value = "TRANSFER";
},
{
name = relationship;
value = ACCEPTED;
}
);
resourceURL = "https://example.com";
};
contactId = "tel:+";
},
{
attributeList = {
attribute = (
{
name = "display-name";
value = bob;
},
{
name = capabilities;
value = "TRANSFER";
},
{
name = relationship;
value = ACCEPTED;
}
);
resourceURL = "https://example.com";
};
contactId = "tel:+";
}
)
This starts from a { and i do not get a key for the next object so that i can get the values inside the JSOn
Is there any easier way to remove this or any other so that i can get values like name and value and store them in an array.
Thanks in advance

Answer 1

You have keys for all.
In fact you seem to get confused on array which is a part of attribute.
The outermost key is Data which contains array.
For each object of the array you have :
The first key is attributeList & contactD.
The value of attribute key is an array of 3 values. Each array contains key value pairs. keys are name & value.

I am not sure from where you got [Allinfo objectForKey:#"contact"]. Try to parse like below..
NSDictionary *Allinfo = [json objectForKey:#"Collection"];
NSArray *dataArray = [Allinfo objectForKey:#"Data"];
for(NSDictionary *dic in dataArray)
{
NSDictionary *attributeList=[dic objectForKey:#"attributeList"];
NSArray *attributeArray=[attributeList objectForKey:#"attribute"];
NSString *resourceURLString=[attributeList objectForKey:#"resourceURL"];
NSString *contactIdString=[dic objectForKey:#"contactId"];
for(NSDictionary *attributeDic in attributeArray)
{
NSString *nameString=[attributeDic objectForKey:#"name"];
NSString *valueString=[attributeDic objectForKey:#"value"];
}
}

You can use the following method for this
NSError *e = nil;
NSArray *itemArray = [NSJSONSerialization JSONObjectWithData:[response dataUsingEncoding:NSUTF8StringEncoding] options: NSJSONReadingMutableContainers error: &e];
if (!itemArray) {
NSLog(#"Error parsing JSON: %#", e);
} else {
for(NSDictionary *item in itemArray) {
//Your Data
}
}
