Answer 1

NSString *query = [url query];
NSArray *queryComponents = [query componentsSeparatedByString:@"&"];

Now you got all strings in queryComponents like

param1=value

Now you can get first value like that

NSArray *firstParam = [[queryComponents objectAtIndex:0] componentsSeparatedByString:@"="];

[firstParam objectAtIndex:0] is the name of param
[firstParam objectAtIndex:1] is value of the param
