Convert NSString to ASCII Binary Equivilent (and then back to an NSString again)

Question

I\'m having some problems with this.

I want to take an NSString and convert it to an integer array of only 0,1 values that would represent the binary equivalent of an as

Answer 1

Convert NSString to Integer:(got it from link Ben posted )

// NSString to ASCII
NSString *string = @"A";
int asciiCode = [string characterAtIndex:0]; // 65

then pass it to function below :

NSArray *arrayOfBinaryNumbers(int val) 
{
    NSMutableArray* result = [NSMutableArray array];
    size_t i;
    for (i=0; i < CHAR_BIT * sizeof val; i++) {
        int theBit = (val >> i) & 1;
        [result addObject:[NSNumber numberWithInt:theBit]];
    }
    return result;
}
