Frage

- (void) _getPoints: (double*)arg1
{
  NSLog(@"%f", arg1);
}

This works for double and float, but not double*. Any help is appreciated.

War es hilfreich?

Lösung

Assuming arg1 is pointing to some sort of double you want:

- (void) _getPoints: (double*)arg1
{
  NSLog(@"%f", *arg1);
}

You might want to refer to pointer tutorial to understand what is going on, such as this.

Andere Tipps

Consider replacing arg1 with arg1 ? *arg1 : @"null"
