Im using one function [(NSString*) str characterAtIndex:(some
index)] . I
have a text view where I can enter space,enter and return
characters. I
wanted to know the value of 'Enter' and 'Return' key.
The return and enter keys by default are bound to insertNewline:,
which in a text view that is not a field editor will by default
insert \n, i.e. 0xa. However, for general text processing you should
not depend on any particular break character; instead, you should use
NSString methods like getLineStart:end:contentsEnd:forRange:,
lineRangeForRange:, getParagraphStart:end:contentsEnd:forRange:, or
paragraphRangeForRange:, which will handle any of the commonly used
break characters.
