i m getting string server, have split these queries , implement local db code, how can (handle string like, split , converting)

sql://query=create%20table%20employee%20(empid%20int%2c%20empname%20text%2c%20age%20int%2c%20gender%20text%2c%20sync%20int)&sync=1&syncquery=select%20*%20from%20employee%20where%20sync%3e0%20limit%2010&onadded=update%20employee%20set%20sync%3d0%20where%20empid%3d%27%25empid%25%27&onmodified=update%20employee%20set%20sync%3d0%20where%20empid%3d%27%25empid%25%27&ondeleted=delete%20from%20employee%20where%20empid%3d%27%25empid%25%27&syncfrequency=300"];

here done decoding process,by using below code

nsstring *decodedtext = [query stringbyreplacingpercentescapesusingencoding:nsutf8stringencoding]; nslog(@"original text: %@", decodedtext);` 

but want split queries using keys(query, sync,sync query....), how can do

nsstring *query=[nsstring stringwithformat:@"%s","query=create%20table%20employee%20(empid%20int%2c%20empname%20text%2c%20age%20int%2c%20gender%20text%2c%20sync%20int)&sync=1&syncquery=select%20*%20from%20employee%20where%20sync%3e0%20limit%2010&onadded=update%20employee%20set%20sync%3d0%20where%20empid%3d%27%25empid%25%27&onmodified=update%20employee%20set%20sync%3d0%20where%20empid%3d%27%25empid%25%27&ondeleted=delete%20from%20employee%20where%20empid%3d%27%25empid%25%27&syncfrequency=300"];  nsstring *decodedtext = [query stringbyreplacingpercentescapesusingencoding:nsutf8stringencoding];  nsarray *firstsplit = [decodedtext componentsseparatedbystring:@"&"];  for(nsstring *currentstring in firstsplit) {      nsdictionary *dict = [[nsmutabledictionary alloc] init];     [dict setvalue:[[currentstring componentsseparatedbystring:@"query="] lastobject] forkey:@"query"];     [dict setvalue:[[currentstring componentsseparatedbystring:@"sync="] lastobject] forkey:@"sync"];     [dict setvalue:[[currentstring componentsseparatedbystring:@"syncquery="] lastobject]forkey:@"syncquery"];     [dict setvalue:[[currentstring componentsseparatedbystring:@"onadded="] lastobject] forkey:@"onadded"];     [dict setvalue:[[currentstring componentsseparatedbystring:@"ondeleted="] lastobject] forkey:@"ondeleted"];     [dict setvalue:[[currentstring componentsseparatedbystring:@"syncfrequency="] lastobject] forkey:@"syncfrequency"];      nslog(@"%@",dict); }
