Length of Allocated Array

Question

I have this objective-c code, but I cant find the size of the allocated array.

NSArray *myArray = [[NSArray alloc] initWithObjects:@"Apple", @"Orange", @"Banana",      @"Plum", nil];
[myArray objectAtIndex: 0];
[myArray length];

XCode give-me this error:

"No visible @interface for "NSArray" declares the selector length"

What can this be?

I tried this, but it gave me this error: "No Known class method for selector 'count' — , Dec 19 '12 at 00:23
Right, count isn't a class method it's an instance method. So you should do [myArray count] as stated in the answer below. — Jim Merkel, Dec 19 '12 at 00:46

What is length? If you want to find the number of objects in the array use:

[myArray count];

If you want to find the size, check this link out:

It worked, thank you. Strange a little this logic, about counting the number of objects, instead of characters. – Dec 19 '12 at 13:46

@Sedate Alien is right. [myArray count] or myArray.count are the ways to get the length.

It looks like you might be missing something simple like the framework containing NSArray ... not sure how, since most templates include it, but just in case make sure you have #import <Foundation/Foundation.h> and added the actual framework to your project

Roughly: (Project->Build Phases->Link Binary With Libraries... -> "+" button->Foundation)
