Question

I’m sorry for this (probably very) noob question, but i’ve been asked about this and can’t see what’s wrong (i’m java tought..)
This is what I have, data is loaded via JSON:

NSDictionary *myvalues = [myres objectForKey:@"0"];

this is the content if I output via NSLog:

({id = "1a";myval = 5;},
 {id = "2b";myval="24.6";})

how do I iterate through myvalues and how do I get the values id and myval? Something like this i’m getting stuck:

for (NSArray* myvals_array in myvalues)

First it looks like the returned value is an Array, the content inside of the parentheses() denotes this. So I would try and set it as such instead of a Dictionary. Then you can enumerate through the array of dictionary’s and get each dictionary inside:

 for (id object in myvalues) {
        NSDictionary *currentObject = (NSDictionary*)object;
        NSString *myID = [currentObject valueForKey:@"id"];
        NSString *myValue  = [currentObject valueForKey:@"myval"];
        NSLog(@"ID:%@   VALUE:%@",myID,myValue);
    }

This will enumerate through the array and create a dictionary for each entry, then get the values for each of the two elements inside. I just NSLog() them here but you can do whatever you want with the values.
