Simple array loop question Objective-C

Question

How can you make this work?

numbers = [[NSMutableArray alloc] initWithObjects: ({int x = 0; while (x <= 60 ) { return x; x++; } })];

Thanks :)

Answer 1

NSMutableArray * array = [[NSMutableArray alloc] init];

for (int i = 0; i <= 60; ++i) {
  [array addObject:[NSNumber numberWithInt:i]];
}

Answer 2

int myStrangeNumberOfItems = 61;

NSMutableArray * numbers = [[NSMutableArray alloc] initWithCapacity: myStrangeNumberOfItems];
for (int i = 0; i < myStrangeNumberOfItems; i++) {
    [numbers addObject:[NSNumber numberWithInt:i]];
}

Answer 3

First, an NSArray can only hold objects, not primitives. You can add the objects within a for loop like so.

NSMutableAray * numbers = [[NSMutableArray alloc] init];
for (int x = 0; x <= 60; x++)
    [numbers addObject:[NSNumber numberForInt:x]];
