Question

I m performing JSON parsing.
In return i m getting the result something like this:

{"login":"FALSE","userid":"Please enter correct Email Address"}

I want to retain the userid: message into some variable, so that i can perform functions on the basis of userid itself.

Suggestion please.

Thanks

You can try with a framework such as this,https://github.com/stig/json-framework

Example usage would be, assuming userId is declared in your header file.

SBJSON *parser = [[SBJSON alloc] init];

NSArray *statuses = [parser objectWithString:json_string error:nil];

userId = [statuses valueForKey:@"userid"]; 

Now userId retains the value for the json value for userid from the json string

UPDATE: If you’re only supporting iOS >= 5.0 I would suggest the built in NSJSONSerialization class. If this is the case, your code will look more like this..

NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSMutableArray *jsonList = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:nil];

userId = [jsonList valueForKey:@"userid"];

NSLog(@"userid: %@", userId); // will print "Please enter correct Email Address"

Hope this helps !
