Im using one function [(NSString*) str characterAtIndex:(some

have a text view where I can enter space,enter and return
characters. I
wanted to know the value of 'Enter' and 'Return' key.
Sample code that Im using is --
int i ,index = 0,len = [str length];
for(i=0; i<len; i++)
{
if( [str characterAtIndex:i] == 32) // this 32 = for Space.
index++;
else
break;
}
Well, the Carbon header file Events.h lists the following:
/* MacRoman character codes*/
enum {
kEnterCharCode = 3,
kReturnCharCode = 13,
kSpaceCharCode = 32,
};
The return and space characters have had those values for decades
now, so the only one you'd need to confirm is the enter key. I
haven't tried it with Unicode as yet.
