Example of [NSDictionary getObjects:andKeys:]

Question

I couldn\'t find a working example of the method [NSDictionary getObjects:andKeys:]. The only example I could find, doesn\'t compile. I provided the errors/warnings

Answer 1

Here's the correct way to use this method:

NSDictionary *myDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"1", @"A", @"2", @"B", nil];

NSInteger count = [myDictionary count];
id objects[count];
id keys[count];
[myDictionary getObjects:objects andKeys:keys];

for (int i = 0; i < count; i++) {
  id obj = objects[i];
  id key = keys[i];
  NSLog(@"%@ -> %@", obj, key);
}
