how to add nil to nsmutablearray?

Question

NSArray *array = [[NSArray alloc] initWithObjects:@\"ΕΛΤΑ\",
                      @\"ΕΛΤΑ COURIER\", @\"ACS\", @\"ACS ΕΞΩΤΕΡΙΚΟ\", 
                      @\"DHL\",          


        

Answer 1

pass your object through this method when adding to array to avoid attempt to insert nil object from objects crashes.

-(id) returnNullIfNil:(id) obj  {
    return (obj == nil) ? ([NSNull null]) : (obj);
}

[NSNull null] returns an null object which represents nil.
