Question

I have an NSString of integer values. I need to add each one of the integers as a separate object in an NSMutableArray.

I tried characterAtIndex: but I keep getting errors…

P.s. I’ve solved over 30 problems thank’s to stackoverflow’s search, but didn’t find any information on this problem.

NSMutableArray *results = [NSMutableArray array];

for (int i = 0; i < [string length]; i++)
{
    NSString *substr = [string substringWithRange:NSMakeRange(i,1)];
    [results addObject:[NSNumber numberWithInt:[substr intValue]];
} 

NSLog(@" %@ separated into: %@", string, results);
