Without loop you can use this:

NSString *myString = @"ABCDEF";
NSMutableString *tempStr =[[NSMutableString alloc] initWithString:myString];

if([myString length] != 0)
{
    NSError  *error  = NULL;

    // declare regular expression object
    NSRegularExpression *regex =[NSRegularExpression regularExpressionWithPattern:@"(.)" options:NSMatchingReportCompletion error:&error];

    // replace each match with matches character +  e.g. 'A' with 'A '
    [regex replaceMatchesInString:tempStr options:NSMatchingReportCompletion range:NSMakeRange(0,[myString length]) withTemplate:@"$0 "];

    // trim last  character
    [tempStr replaceCharactersInRange:NSMakeRange([tempStr length] - 1, 1) withString:@""];

    // split into array
    NSArray * arr = [tempStr componentsSeparatedByString:@" "];

    // print
    NSLog(@"%@",arr);
}

This solution append space in front of each character with the help of regular expression and uses componentsSeparatedByString with to return an array
