Question

I am making a battleships game to play in console – How do you NSLog strings so they appear as a 10 x 10 grid and not a long list. Each coordinate is @”X” object from the boardArray.
Ideally I would like to do it in a loop – but, whatever !
Thank you.

NSMutableArray *boardArray = [[NSMutableArray alloc]initWithCapacity:110];
NSMutableString *blank =[[NSMutableString alloc]initWithString:@"X"];

for (int x = 0; x < 101; x++) {
    [boardArray insertObject:blank atIndex:x];
}


for (int x = 0; x < 100; x++){

    // what goes here to print (NSLog) a 10 x 10 grid of objects
    // each object is a string @"X" from the boardArray.

}

Quick Example:

// Create Array (01, 02, 03, 04, 05, etc.)

NSMutableArray *theArray = [[NSMutableArray alloc]init];
for (int i = 0; i < 100; i++) {
    [theArray addObject:[NSString stringWithFormat:@"%02d",i]];
}

// Print Array

for (int i = 0; i < 10; i++) {
    NSArray *subArray = [theArray subarrayWithRange:NSMakeRange(0+(i*10),10)];
    NSLog(@"%@",[subArray componentsJoinedByString:@" "]);
}

Output:

00 01 02 03 04 05 06 07 08 09
10 11 12 13 14 15 16 17 18 19
