Apple's documentation of the method intValue reads as follows:
The integer value of the receiver’s text, assuming a decimal
representation and skipping whitespace at the beginning of the
string. Returns INT_MAX or INT_MIN on overflow. Returns 0 if the
receiver doesn’t begin with a valid decimal text representation of
a number.
Thus, the string @"0" returns 0, which for my purposes is
acceptable, but a string such as @"X" also returns 0, which isn't
acceptable. Is there an easy way to distinguish between these two
situations, or do I have to write a bunch of extra code to
distinguish between them?
Use NSScanner's scanInt:
