Give out all class properties

Question

I was just wondering how I could give out everything that is in NSDictionary *info:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

Just to see whats in it. Is there a simple way?

Regars, Philip

What does `Give out everything` mean? – James A Mohler Feb 22 '14 at 22:08 — James A Mohler, Feb 22 '14 at 22:08

Sounds like you want to do:

NSLog( @"info dictionary is %@", info );

in your code.

Passing "info" to NSLog is the same as doing "[info description]", you print out the entire contents (keys and values of your dictionary).

if only everything was that easy. – Michael Dautermann Feb 22 '14 at 22:11
btw is info in this case an array? – Philip Feb 22 '14 at 22:20
no, "`info`" is a NSDictionary, which contains objects or values and the keys that associate with them. – Michael Dautermann Feb 22 '14 at 22:26

Here is one way you can iterate through everything in the dictionary:

NSArray *dictionaryKeys = [info allKeys];
for (NSString *key in dictionaryKeys) {
    // Do something with info[key]
}
