Say you have your ISO-8859-1 encoded string in a varaible isoString of type const char*, then you can create an NSString instance like this:

NSString* str = [[NSString alloc]
    initWithCString: isoString encoding: NSISOLatin1StringEncoding];

Note: Latin-1 and ISO-8859-1 encoding are the same.

With the following code, you can convert it to a UTF-8 encoded C string if needed:

const char* utf8String = [str UTF8String];
