Example of [NSDictionary getObjects:andKeys:] 的示范

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);}

还有一个：

NSDictionary*myDictionary =[NSDictionary dictionaryWithObjectsAndKeys:@"1",@"A",@"2",@"B", nil];NSInteger count =[myDictionary count];
id __unsafe_unretained objects[count];
id __unsafe_unretained 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);}
