While you can mark a literal as an unsigned int by writing e.g. 0x0085U, there's no way to write a 'short' literal in C. So the best you can do is write the numbers as NSCharacterSet *stopCharacters = [NSCharacterSet characterSetWithCharactersInString:[NSString stringWithFormat:@ \t\n\r%C%C%C%C, (unichar)0x0085U, (unichar)0x000CU, (unichar)0x2028U, (unichar)0x2029U]]; I.e. make them unsigned and typecast them to short. Using escape sequences instead as others have suggested is probably the better solution (then you can get rid of the entire -stringWithFormat: call as well and just write the whole string as one literal). This'll work as long as you are using a current version of the llvm compiler, I think. Older versions of the compilers included in Xcode didn't support the Unicode escape sequence as far as I remember.

How to fix warning?
Hi, I am getting the following warning warning: format specifies type 'unsigned short' but the argument has type 'int' [-Wformat] on this statement: NSCharacterSet *stopCharacters = [NSCharacterSet characterSetWithCharactersInString:[NSString stringWithFormat:@ \t\n\r%C%C%C%C, 0x0085, 0x000C, 0x2028, 0x2029]]; What is the best way to fix this?

The type of integer literals in C is “int” by default. If you want them to be shorts (or unsigned, as is the bigger issue in this case), you must cast them either explicitly (by adding the casts in this expression), or implicitly, by assigning the littorals to a variable of the desired type.

I think I understand what the problem is and the fix, but what does the following the opening quote signify?

It’s just a literal ““ character in the string; nothing magic. (The code looks like it’s constructing an NSCharacterSet, and ““ must be one of the characters that should go in the set.) —Jens ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
