I need NSString in binary format how do i print NSString in binary
format
instead of "0001"
obj-c code is uint8 barr[4];
barr[0] =(uint8)num;
barr[1] =(uint8)num>>8;
barr[2] =(uint8)num>>16;
barr[3] =(uint8)num>>24;
i am using [NSString stringwithFormat:@%i,barr[i]]
which %? i need to use to get the byte value(binary data) as it is
from the
array?
This tells you:
http://www.opengroup.org/onlinepubs/009695399/functions/printf.html
It states that the default precision for %i is 1, but Apple appear
to have changed it to 4 (???)
So try %i.1
The Apple version of %i conforms to spec. The default precision is 1
but the precision tells you the *minimum* number of digits that will
be printed, not the actual number.
In any case, if the intention really is to insert the actual raw bytes
into the string, the correct format specifier is %c. However, that is
likely to mess things up badly if the value of a byte is 0.
