How to check if array is null or empty?

Question

I want to check if my array is empty or null, and on base of which I want to create a condition for example.

if(array ==  EMPTY){
//do something
}

Answer 1

null and empty are not the same things , i suggest you treat them in differently

if (array == [NSNull null]) {
    NSLog(@"It's null");
} else if (array == nil || [array count] == 0) {
     NSLog(@"It's empty");
}
