Question

I am trying to parse a rather large json file, and I am beginning to have a bit of an issue

An example of what the JSON looks like is this

{
"info":"info",
"products":[
            {
            "name":"HomeScreen",
            "screens":[
                       {
                       "name":"View Details",
                       "id":1,
                       "title":{
                       "name":"Default_Name",
                       "number":"Default_Number"
                       },
                       "widgets":[
                                  {
                                  "id":8,
                                  "splits":[
                                            {
                                            "control":{
                                            "type":1,
                                            "limitLow":0,
                                            "limitHigh":100
                                            },
                                            "texts":[
                                                     {
                                                     "value":"blah",
                                                     "style":{
                                                     "size":10,
                                                     "colour":"#FFFFFF"
                                                     },
                                                     "test1":"asd",
                                                     "test2":"zxc"
                                                     }
                                                     ]
                                            }
                                            ]
                                  },

And so on

I want to be able to parse the texts values and place them in an object. I have the class created, but I am unable to retrieve the exact values. I have tried doing the following

   NSArray *test = [MainJSON valueForKeyPath:@"products.screens.widgets.splits.texts"];

for(NSDictionary *dict in test){

    NSLog(@"%@", [dict valueForKeyPath:@"value"]);
}

It prints out the values but with loads of brackets as well, and I need to be able to get the exact value from the JSON. I also tried doing

 for(int i = 0; i < [test count]; i++){

    for(NSDictionary *dict in [test objectAtIndex:i]){

        NSLog(@"%@", [dict valueForKeyPath:@"value"]);
    }

}

But same problem. Could anyone tell me what I am doing wrong. I have tried soo many different solutions, but nothing seems to be working.

Thanks in advance

EDIT Output for example I gave is

As you can see a lot of brackets which is deeply frustrating.

Edit2:

Test is an array of NSDictionary objects though, here is the code

   NSString *filePath = [[NSBundle mainBundle] pathForResource:@"json" ofType:@"json"];  
NSData *myData = [NSData dataWithContentsOfFile:filePath];  

NSString *responseString = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding];

NSDictionary *MainJSON = [responseString JSONValue];
NSArray *test = [MainJSON valueForKeyPath:@"products.screens.widgets.splits.texts"];

Edit:

I have been able to get a single value using this code

 for(NSDictionary *dict in [textArray objectAtIndex:0]){

 NSLog(@"%@", [[[[dict valueForKey:@"value"]objectAtIndex:0]objectAtIndex:0]objectAtIndex:0]);
 }

However this is a bit messy.

Answer 1

I figured it out in the end. In the products Object class, I didn’t add in an NSDictionary object into the class object. As I needed to make a dictionary of the screens. Then loop through that dictionary, find the widgets, then create a dictionary of that array, find the splits, then make a dictionary of that array, and then loop through that and so on until I got to texts. Now it works perfectly! 😀
