I am attempting to read a json message using the json.framework. The message is a nested collection of meeting details. My desire is to iterate thought all of the meetings and create local meeting objects with the details read from the message. I see to get list of the 15 meetings that are in the json results but can't get the individual values from the results.
Here is my sample code. I am using a file for the json message so that I don't have to involve the server in this test. The json message can be downloaded here.
-(void)TestParse:(NSString *)response
{
NSString *filePath = [[NSBundle mainBundle]pathForResource:@"conference_calls" ofType:@"json"];
NSString *fileContent =[[NSString alloc]initWithContentsOfFile:filePath];
parser = [SBJsonParser new];
NSArray *results = [parser objectWithString:fileContent];
NSLog(@"Number of itmems in the results: --> %i", [results count]);
for(NSDictionary *conf in results){
//Load local objects with the values of the Conf info.
NSLog(@"This the description %@ ",[c valueForKey:"phone_number"]);
NSLog(@"Number of Items in Dic: %i",[conf count]);
NSLog(@"File contents: %@",[conf description]);
}
The structure of your json is an array of dictionaries. But each dictionary has just a single key called "conference_call", with the value for that key being another dictionary with all the details of that call.
So something like this should work:
for (NSDictionary* call in results) {
// get the actual data for this call
NSDictionary *callDetails = [call objectForKey:@"conference_call"];
NSLog (@"Location is %@", [callDetails objectForKey:@"location"]);
}
Hope that helps.
