Hello,

1) How to read the data from read stream in Objective-C, Below code would give me how many bytes are read from stream, but how to know what data is read from stream?

CFIndex cf = CFReadStreameRead(Stream, buffer, length);

2) How to extract only the 1st 2bytes of NSString in Objective-C in iPhone programming. For Ex: If this is the string

NSString *str = 017MacApp;

1st byte has 0 in it, and 2nd byte has 17 in it.

how do i extract o and 17 into byte array?

I know that the below code would give me back the byte array to int value.

((b[0] & 0xFF) << 8)+ (b[1] & 0xFF);

but how to put 0 into b[0] and 17 into b[1]?

plz help me to solve this.
