How do I override a property?

You must override the set of properties of the parent class. For temporary block assignment. For example - Range UITextView property is selected. How can i do this? Thanks.

-(void)setFoo:(Foo *)newFoo {
  // Do something.
  [super setFoo: newFoo];
}

If you want to block the setter sometimes,



-(void)setFoo:(Foo *)newFoo {
  if (someCondition) {
    [super setFoo: newFoo];
  }
}
