Question

I have this method that makes a call to another method. How to I pass the char[] to it instead of having the char[] inside it?

- (IBAction)goThere(id)sender {

   // char hex[] = {0xFF, 0xFF, 0x15}; <-- this is what I want to pass to elseWhere
   // NSString *text = "some string";  <-- it would be cool to send other things too.

    [self elseWhere];
}

- (void)elseWhere {

char hex[] = {0xDA, 0xFF, 0x15};

...

}

Ideally I would be able to send char[] from goThere, being able to re-use the char[] as needed, unfortunately i’m not advanced in this. thanks

Try this:

-(IBAction)goThere:(id)sender {
    char hex[] = {0xFF, 0xFF, 0x15};
    [self elseWhereWithData:hex length:3];
}

-(void)elseWhereWithData:(char*)array length:(int)length {
    // array is a char array with a length of length.
    // Do stuff....strong text
}
