Answer 1

NSArray is the standard array class in Cocoa/Cocoa Touch. It can contain objects, but not primitives.

You can store integers in an array by wrapping them with an NSNumber object like so:

NSNumber *myInt = [NSNumber numberWithInt:1];

Then you can store it in an array like so:

NSArray *myArray = [NSArray arrayWithObject:myInt];

Answer 2

NSArray *arr = [NSArray arrayWithObjects:@"a", @"b", @"c", nil];

NSArray *arr = [NSArray arrayWithObjects:[NSNumber numberWithInteger:1]
                                       , [NSNumber numberWithInteger:2]
                                       , [NSNumber numberWithInteger:3]
                                       , nil];
