access NSDictionary content

I have an NSDictionary like

{
        nodeAttributeArray =         (
                        {
                attributeName = ReportDate;
                nodeContent = "08-31-1986";
            },
                        {
                attributeName = ReportType;
                nodeContent = PQ1;
            }
        );
        nodeName = Period;
    },
    {
        nodeAttributeArray =         (
                        {
                attributeName = ReportDate;
                nodeContent = "08-31-1987";
            },
                        {
                attributeName = ReportType;
                nodeContent = PQ2;
            }
        );
        nodeName = Period;
    }

I have shown 2 values here. But there are almost 50 such members inside my dict How do开发者_运维百科 I access the contents of this inside a for loop ?

I want the value inside "nodeContent"

Thank you.

From looking at the data structure, it seems to me that the root structure is a List and not a dictionary as you pose in the question. Is that correct? If that is the case, then an iteration for printing the attribute values to the console would be:

NSArray *array; // this is your list with 50 values or so in it
//... some code to load the data into array
NSDictionary *d;
for (NSDictionary *period in array){
    NSLog(@"%@",[period objectForKey:@"nodeName"]);
    for (NSDictionary *nodeAttributeArray in [period objectForKey:@"nodeAttributeArray"]){
        NSLog(@"\t%@=%@",[nodeAttributeArray objectForKey:@"attributeName"],[nodeAttributeArray objectForKey:@"nodeContent"]);
    }
}
