Print keys of NSDictionary instead of values

Question

I download some content from a json webservice.

Is it possible print the keys and not the values instead? For the eventuality of not knowing what the keys are.

Answer 1

for( NSString *aKey in [dictionary allKeys] )
{
    // do something like a log:
    NSLog(aKey);
}

OR

NSLog([dictionary allKeys]);

This should do the trick

Answer 2

You should be able to use the NSDictionary's keyEnumerator method to get the keys, then you can loop through them and print them out.

Borrowing an example from Apple:

NSEnumerator *enumerator = [myDictionary keyEnumerator];
id key;

while ((key = [enumerator nextObject])) {
    NSLog(@"Do something with the key here:%@",key);
}
