    Those "attribute values" look like HTTP request query parameters. Look at the accepted answer of this SO question for a possible solution: http://stackoverflow.com/questions/2225814/nsurl-pull-out-a-single-value-for-a-key-in-a-parameter-string – trojanfoe Aug 30 '13 at 08:19

Well for starters, looks like the data could be considered analogous to an NSDictionary.

You could take this string as an NSString and get an NSArray by sending the message componentsSeparatedByString: with an arg of @"&". 

NSArray *firstArray = [responseString componentsSeparatedByString:@"&"];

Then create an NSMutableDictionary

NSMutableDictionary *mDict = [[ NSMutableDictionary alloc] initWithCapacity: firstArray.count ];

Then use fast enumeration to populate the key value pairs. 

for ( NSString *aKVP in firstArray) {
    NSArray *tempArray = [aKVP componentsSeparatedByString:@"="];
    [mDict setValue: tempArray[1] forKey: tempArray[0] ];
}

Then you have a data structure you can use. You can access the values by key to set button labels or whatever else you want to do.

Other approaches would include things like NSScanner or NSRegularExpression but this is straight forward and flexible if you need the rest.
