I have a JSON response from a web server that looks like this:
{"success":true, "token":"123456"}
and I want to use that in an if statement, and compare it with "YES".
However, doing this doesn't work:
NSDictionary *response = [response JSONValue]; // the JSON value from webservice response, converted to NSDictionary
if ([response objectForKey:@"success"]){} // does not work
if ([response objectForKey:@"success"] == YES){} // does not work
if ([[response objectForKey:@"success"] integerValue] == YES) {} // does not work...erroneous probably
How can I work around this? Typecasting in Boolean yields a warning too
since [response objectForKey:@"success"]
does not work, what happens when you try [response valueForKey: @"success"]
?
I suspect it returns a NSNumber and then you can do something like:
NSNumber * isSuccessNumber = (NSNumber *)[response objectForKey: @"success"];
if([isSuccessNumber boolValue] == YES)
{
// this is the YES case
} else {
// we end up here in the NO case **OR** if isSuccessNumber is nil
}
Also, what does NSLog( @"response dictionary is %@", response );
look like in your Console? I see the JSON library you're using does return NSNumber types for objectForKey
, so I suspect you might not have a valid NSDictionary.
