I know there must be a better way but this was all I could come up with as a rookie cocoa programmer to get a substring out of a very long NSString from a textView growing as the operator types in the message content. The receive buffer in the chip I am talking to will only take 80 characters before an XOFF (buffer 2/3 full). XON occurs when the chip buffer is reduced to about 1/3 full. This routine is in a thread that reads data from the chip as well.
char sndBuffer[65]; int j; characterIndex++; // is always sitting at the last character sent so advance to the next character in string. for (j = 0; j < 65; j++) { sndBuffer[j] = [string characterAtIndex:characterIndex]; characterIndex++; } sndBuffer[j] = 0x00; substring = [NSString stringWithUTF8String:sndBuffer]; It works flawlessly, but there oughta be a way without reverting to C? Suggestions very much welcomed.
