initialize an NSArray with a list of objects

• David Alter initialize an NSArray with a list of objects May 17 2006, 00:53
  Is there a way to initialize an NSArray with a list of strings like I
  can do in C
  
  Example
  
  the C way
  char * myList[] = {"item1", "item2", "item3" }
  
  I tried this, and it only picked up the first item
  
  NSArray * myList = {@"item1", @"item2", @"item3" }
  
  Thanks for the help

  The first thing that comes to mind is:
  
  NSArray *myArray = [NSArray arrayWithObjects:@"item1", @"item2",
  @"item3", nil];
  
  It seems unlikely that there would be an operator (like {}) that
  would create cocoa collection objects grafted into objc.

  NSArray* myList = [NSArray arrayWithObjects:@"item1", @"item2", @"item3", nil];
  
  (note you will need to retain myList if you want to have the array
  last past the current autorelease pool)
  
  Anyway the docs for NSArray outline these and related API
  (initWithObjects:, etc.) and all that is available directly from Xcode
  via a simple option double click of a class name (i.e. option-double
  click "NSArray").

  You'll want to use the arrayWithObjects class method, and remember to
  cap it off with nil.  Use like this:
  
  NSArray *myList = [NSArray arrayWithObjects: @"item1", @"item2",
  @"item3", nil];

  Sort of.  You can't use the curly brackets, but you can initialize it
  with a variable-length list.
