How to convert part of a char array into an NSString*?

Question

char arr[] = "abcdefg";
// I know I can do this
NSString *s = [[NSString alloc] initWithCString:arr encoding:NSUTF8StringEncoding];

If I want to convert part of the arr array into an NSString*? say cde rather then the whole string abcdefg? How do I achieve that?

maybe use initWithUTF8String? – CodaFi Mar 06 '12 at 05:48 — CodaFi, Mar 06 '12 at 05:48

NSString *s = [[NSString alloc] initWithBytes:arr + 2
    length:3 encoding:NSUTF8StringEncoding];

Thank you @rob, It worked! But it is strange that there's no method like `initWithBytes:(const char*)buffer index:(int)i length:(int)l encoding:(NSStringEncoding)e`. – neevek Mar 06 '12 at 06:06
You could always write a category. – DrummerB Aug 12 '12 at 15:25
