Arrays of NSObjects in Objective-C

I've created an object, and now I'm trying to create an array full of these objects. I've tried a few different things with no success.

How can I do this?

You can use an NSArray, take a look at Apple's documentation.

If you wanna add them incrementally consider using a mutable collection like an NSMutableArray (here in the doc)

You can do it one of two ways, with NSArray or NSMutableArray.

id obj1, obj2, obj3;

// This creates a static array
NSArray *array = [NSArray arrayWithObjects: obj1, obj2, obj3, nil];

// This creates a dynamic array
NSMutableArray *mutarray = [NSMutableArray array];
[mutarray addObject:obj1];
[mutarray addObject:obj2];
[mutarray addObject:obj3];

NSMutableArray * arrayOfFoos = [NSMutableArray array];
for (int i = 0; i < 100; ++i) {
  Foo * f = [[Foo alloc] init];
  [arrayOfFoos addObject:f];
  [f release];
}
