Hi, I am trying to find way to convert the NSString object into
its bit
pattern and convert that bit pattern into another NSString object,
For Example if I have
NSString *origStr = @"Hello":
NSString * bitPatternoforigStr ;
no I want to convert it to the bit pattern if Hello and return an
object of
type NSString with bit pattern.
it should be something like;
bitPatternoforigStr = @"0101101001100010010011111000010101100101" ;
Can someone help me in this.
Break it down.
A string is a sequence of characters. Retrieve each character,
determine its bit-pattern, then append that pattern to an
NSMutableString. Now you have to figure out how to turn a character
into its bit-pattern. So break that down.
A character (or any simple non-floating type) is a sequence of bits.
If you know the C operators for Boolean AND and SHIFTS (& and >> and
<<), then you know enough to isolate single bits from a character.
Then you just test each bit and append either a '0' or '1' character
to the accumulating NSMutableString.
