How to parse this JSON response into a key & value pairs array - objective-c

Question

there are a lot of questions like this and i'm experienced with json format too but i couldnt parse the response below(at the bottom):
I'm using NSJSONSerialization for parsing the response into NSDictionary but the it gives the error like below:
My code:
NSString *subURL= sharedDa.ip;
NSData *data=[NSData dataWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://192.168.69.230/tsadmin.php?tssearch=%#", subURL]]];
NSError *error=nil;
NSDictionary* portsResult=[NSJSONSerialization JSONObjectWithData:data options:
NSJSONReadingMutableContainers error:&error];
NSDictionary * tempPorts;
NSString *k;
for(k in [portsResult allKeys]){
tempPorts = [portsResult objectForKey:k];
NSLog(#"Temporary ports: %#", tempPorts);
}
And the error code is below:
2012-09-28 18:47:37.508 BNTPRO ST Manager[2609:fb03] -[__NSArrayM allKeys]: unrecognized selector sent to instance 0x6b83ed0
2012-09-28 18:47:37.511 BNTPRO ST Manager[2609:fb03] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayM allKeys]: unrecognized selector sent to instance 0x6b83ed0'

terminate called throwing an exception(lldb)
now my data snippet is: [{"k1":{"v":"0"}},{"k2":{"v":"0"}},{"k3":{"v":"0"}},{"k4":{"v":"0"}},{"k5":{"v":"0"}},{"k6":{"v":"0"}},{"k7":{"v":"1"}},{"k8":{"v":"0"}},{"k9":{"v":"1"}},{"k10":{"v":"0"}},{"k11":{"v":"1"}},{"k12":{"v":"0"}},{"k13":{"v":"1"}},{"k14":{"v":"0"}},{"k15":{"v":"0"}},{"k16":{"v":"0"}}]
but it still gives the same error.. even i decşare the iVar as NSDictionary why does it complain of nsmutable array??

Answer 1

The JSON you're parsing is an array, not an object. So the result of [NSJSONSerialization JSONObjectWithData...] is not an NSDictionary *, but an NSArray * instead.
For example, for the JSON data
[{"k1":{"v":"0"}}, {"k2":{"v":"0"}}]
You can use something similar to this code (don't have xcode right now to try to run it):
NSArray * arr = [NSJSONSerialization JSONObjectWithData:data options:...];
int i;
for (i = 0; i < [arr count]; i++) {
NSDictionary * dic = [arr objectAtIndex:i];
NSString * k;
for (k in [dic allKeys]) {
NSLog(#"Temporary ports: %#", [dic objectForKey:k]);
}
}
