Check NSDictionary is Empty or not - Objective C

If you are an iOS developer you will need to use data type called NSDictionary.

When I m implementing web service access ( REST type , JSON output) I needed to populate data using using a NSDictionary. It worked fine but there was an issue coming when web service data is empty. So this case I had to find a way to check dictionary is empty or not either null or not.

I have tried below way but exception thrown.

[responseObject count];

Then I have tried and no errors was fired for empty list. Happy coding.

if([NSNull null] != [responseObject objectForKey:@"YOUR_JSON_OBJECT_NAME"]) {

//Wow this worked.

}
